Turnkey renovation in Lisbon: what it includes and what to check

In a turnkey project, one entity takes contractual responsibility for the agreed scope of design, coordination and construction, handing the property over ready for use on the agreed terms. It may apply to an apartment renovation in Campo de Ourique, a building refurbishment or a new house in Cascais. Convenience does not simply come from having one contact: it depends on a proposal that clearly states what is included, what is excluded, who prepares the design information, who handles the planning process and how changes are approved during the work.

“Turnkey” is not a legal category and does not remove the need for technical checks. It is a way of organising a contract. Whether design documents, a licence, prior notification or another procedure is required still depends on the particular intervention, the property and the relevant municipality. Before comparing prices, compare the scope and the documents each company undertakes to provide.

TL;DR

• “Turnkey” is a contracting model, not a legal planning category: the applicable procedure depends on the nature, location and characteristics of the work.
• Its main benefit is placing the contracted coordination with one point of contact, provided responsibilities are written into the contract.
• Before signing, check the company’s IMPIC qualification and whether its class covers the total value of the work.
• The proposal should identify works, material references, exclusions, estimated programme, payments, handover and rules for changes.
• The client retains duties of their own, including decisions, access, approvals and condominium obligations.
• In older buildings, work not visible in the initial survey should follow a written process of recording, pricing and approval before it proceeds.

What does a turnkey project mean in practice?

you appoint a coordinated outcome and scope rather than a collection of separate services that you must bring together.

Under separate appointments, an owner may choose an architect, a specialist engineer, a contractor, electrician, plumber, joiner and kitchen or window suppliers. Each party is responsible for its own appointment. Difficulties tend to arise at the interfaces: electrical services have to align with fitted furniture; waterproofing should be complete before finishes are installed; windows should only be ordered once openings are confirmed; and selected equipment must fit the available services, technical clearances and access routes.

In an integrated arrangement, the appointed company may bring these tasks together in one process. That does not mean everything is automatically included. The contract should identify the entity accountable to the client, the designers involved where projects are required, the expected documentary deliverables, and how coordination will work between in-house teams, suppliers and subcontractors.

Depending on the property and the proposal, the service may include:

• Survey and assessment: measurements, photographs, visible-condition checks of walls, floors, ceilings, existing services and site access. In an older property, the survey should also identify areas that cannot be confirmed without opening up.
• Architectural and specialist design, where required: space planning, structure, water and drainage, electricity, energy performance, acoustics or other matters relevant to the project.
• Interior specification: finishes, sanitaryware, taps, joinery, lighting, appliances and fixed furniture. Three-dimensional images can support choices, but they do not replace drawings, measurements, technical data sheets or specifications.
• Preparation of the planning process: preparation and submission of the documents contractually allocated to the company, where the intervention is subject to municipal control.
• Construction: protection of retained areas, demolition, building work, technical services, waterproofing, finishes, painting, joinery and the items actually included.
• Management, coordination and handover: programming work fronts, tracking outstanding decisions, recording changes, final cleaning where included and a list of work to complete or rectify.

The term has no standard scope. One proposal may include a fitted kitchen, wardrobes, decorative lighting and final cleaning; another may end after painting, leaving those supplies to the client. There may also be significant differences in municipal fees, utility connections, waste removal, public-space occupation, lift protection or repairs to common parts. The commercial label matters less than a verifiable schedule of works, materials and exclusions.

For that reason, request a dated version of the proposal and make sure drawings, finish schedules, measurements, programme and commercial conditions are identified as contract appendices. Where several versions exist, state which one takes precedence. This helps avoid later disputes about whether a conversation, reference image or verbal estimate changed the agreed scope.

Turnkey or separate trades?

appointing separate trades can give you direct control over each supplier, but it places coordination and interface risk with you — or with someone you appoint.

There is no single right option for every owner. The decision depends on the property, complexity, availability of the decision-maker and the capacity to manage orders, access and sequencing. On a small project with clearly defined work and no change to services, separate suppliers may be workable. On a refurbishment involving demolition, layout changes, a new kitchen, services and constrained timings, coordination becomes a substantial part of the project.

The comparison must be made on an equivalent basis. A quote that appears cheaper may omit demolition, substrate preparation, waterproofing, protection of common areas, lighting, waste removal, equipment or material supply. It may also give a duration without stating when it begins: on appointment, access to the property, municipal approval or delivery of client-selected materials.

Separate appointments are not automatically cheaper, and an integrated route is not automatically more expensive. Some costs and risks only become visible when the whole process is considered: the owner’s time, site visits, design coordination, deliveries on different dates, rework and responsibility for a problem between two trades. Always compare quotations for the same scope, the same material references and the same rules for unforeseen conditions.

If you appoint separate trades, create a simple responsibility matrix. State, for example, who closes walls after services are installed, who supplies and fits the shower screen, who confirms final worktop dimensions, and who protects completed finishes. If you choose turnkey, ask for that same allocation to be reflected in the company’s proposal.

What a turnkey proposal should contain

what will be done, the material references, the conditions, the estimated programme, the price and the process for changes.

A vague proposal is difficult to compare and almost impossible to manage once work begins. Before looking only at the final figure, check whether the document answers practical questions: which walls are removed? Which pipes are replaced? Which finish has been allowed for? Is wall preparation before painting included? Who measures, supplies and installs fitted furniture? Do client choices have an allowance or a named reference product?

1. Scope by room and trade. “Bathroom renovation” is not enough. The document should identify, for example, removal of finishes, water-service replacement, drainage work, waterproofing, surface preparation, finishes, sanitaryware, shower tray, enclosure, ventilation, lighting and painting. The same approach applies to kitchens, bedrooms, living rooms, façades and external works.
2. Material references. State brand, range, model, finish, size or, where selection is not final, an allowance. “Premium tiles” or “quality taps” is not sufficient. To compare options, you need to know what has been allowed for, whether fitting is included and what happens if the chosen item exceeds the allowance.
3. Exclusions. Appliances, loose furniture, curtains, municipal fees, public-space occupation, energy certificates, utility connections, design work, tests, cleaning, common-part repairs and work arising from pre-existing damage should be identified when they are not included.
4. Design and planning process. The proposal should say who surveys the existing condition, prepares drawings, coordinates specialist design, signs responsibility documents, submits material and responds to requests for clarification. Check who pays fees and charges as well.
5. Programme and stages. Record start conditions, estimated duration, principal milestones and events that can affect timing, such as material approvals, access, municipal procedures or lead times. A useful programme shows dependencies, not only a completion date.
6. Payments linked to verifiable milestones. Rather than setting payments only by calendar date, link them to identifiable work, measurement records or supplies actually delivered, as agreed in the contract.
7. Variations and omissions. Define how they are identified, who prices them, what information must accompany a request, who approves them and how they affect the programme. Include both client-requested changes and hidden conditions discovered on site.
8. Handover. Provide for an inspection visit, a snag list, responsibility for each correction and an agreed period for completing recorded items. Keep photographs and handover communications.

For contract clauses, see also our guide to essential clauses in a Lisbon renovation contract. When receiving two quotes, turn them into a comparison grid: use rows for demolition, services, waterproofing, finishes, joinery, kitchen, windows, lighting, planning, waste and cleaning. An exclusion is then less likely to remain hidden in a final note.

Why a global price does not cover everything

A global price covers the scope actually described. It does not, by itself, cover matters not identified in the survey, not listed in the appendices or later changed by the client. In an older building, opening a floor or wall can reveal decayed timber, pipework unsuitable for reuse, unidentified electrical installations or a substrate requiring additional preparation before finishes can be applied.

The aim is not to accept extra work without control. It is to define a clear process: immediate notification, photographic record, technical explanation, possible alternatives where they exist, a proposal with price and estimated programme effect, and written approval before the additional work proceeds. In urgent situations, the contract should specify how necessary work to avoid damage or risk is communicated and recorded.

It is also useful to separate an “unforeseen condition” from a “desired upgrade”. Changing a selected tile for a more expensive option, moving the kitchen or adding decorative lighting are scope changes. Repairing a beam discovered during opening-up may be a hidden condition. Both should be recorded, but their reason and assessment method are not necessarily the same.

Planning: the contract does not change the rules

the contracting model does not change the planning control that applies; that control depends on the nature, location and characteristics of the intervention.

Portugal’s legal framework for urban development and building work provides for planning-control procedures and exemptions. In practice, you should not assume that internal work is exempt merely because it is described as a renovation or decoration project. Lisbon City Council provides information on building-work licensing; the position for your project should be checked with the competent municipality and responsible professional before the final scope is fixed or a start date is contracted.

In Lisbon, it is important to distinguish the procedure that applies to the intervention from the private contractual arrangements between owner and company. A proposal may allocate preparation of documents or coordination of designers to the company, but that private allocation does not alter municipal requirements, responsibility statements, documents or fees that may apply.

• As Minhas Obras. Lisbon City Council provides information on this service and planning conditions in its urban-planning FAQs. Check whether your intervention fits the service, which documents are required and what conditions apply to the property.
• Programme planning. Allow time for preparing documents, submitting requests, answering requests for clarification and receiving decisions. Do not treat a construction duration as though it begins before the conditions for starting are in place.
• Competent municipality. Cascais, Oeiras, Sintra, Loures and other municipalities have their own procedures, platforms, fees and regulations. Guidance applicable in Lisbon does not replace checking the council where the property is located.

If the work may affect a façade, roof, common areas, structure, shared services or public space, address it at the feasibility stage. Scaffolding, a skip, hoarding or a loading reservation can introduce separate procedures and costs. Before fixing a solution in Lisbon, consider checking the building’s planning records before fixing a solution.

“Cosmetic” work? Check before starting

Work that looks cosmetic may have technical or planning consequences. Removing a wall between the kitchen and living room, opening an aperture, increasing floor loads, placing equipment on the façade or altering a common area should not be decided solely from inspiration photographs. In older buildings, the visible layout does not always reveal the structural role of a wall, timber elements or the route of shared services.

Ask the competent professional to confirm what is needed before demolition is appointed. Review available drawings, as-built information where it exists, planning records and known previous alterations. If the building is subject to heritage constraints, if the work affects its external appearance or if roof work is involved, the checks should be even more careful.

The same applies to loads and services. A heavy bath, stone worktop, new outdoor unit or relocated kitchen may require confirmation of structural support, drainage, ventilation, electrical supply and effects on common elements. “It is only an internal change” is not a substitute for a project-specific assessment.

How to check that the company is qualified

request the contracting entity’s details and check its qualification with IMPIC before signing.

Construction activity in Portugal is subject to qualification requirements. IMPIC provides official information on access to construction activity and a search facility for holders of private-works contractor alvarás. For private works, the company responsible for execution should hold an appropriate qualification; the alvará class is relevant to the total value of the work. IMPIC states that a private-works contractor certificate permits works up to €40,000 excluding VAT, while alvará classes have their own value limits.

Do not confuse requirements for public works with the checks useful on a private project. According to IMPIC’s frequently asked questions, a private-works contractor certificate is not linked to categories or subcategories; on a private project, focus on the qualification, its validity and whether the class is suitable for the contractual value. See IMPIC’s construction-activity FAQs and its guidance on the class applicable to private works.

1. Request the company name, tax number and qualification number. Do not rely only on a trading name or business card.
2. Search for the entity on the IMPIC portal. Compare the name and details found there with those in the proposal.
3. Check suitability for the total contract value. Confirm that the alvará class covers the contractual value and that the document belongs to the entity responsible for execution.
4. Compare the entity on the qualification with the contract and invoices. The company signing, receiving payments and answering for the work should be clearly identified.
5. Keep evidence. Save a copy of the search result, dated proposal and contract. It is useful if the information has to be checked later.

A company may use subcontractors for particular work packages. That is different from leaving the client uncertain about who is accountable for the whole. The contract should state which entity is accountable to you for the agreed scope, how changes are communicated and who coordinates work that overlaps in the same space.

What remains the client’s responsibility

decisions, approvals, access and any duties that the law, the contract or condominium arrangements do not validly transfer.

Appointing a company to provide contracted coordination does not remove the owner’s role. The client still sets priorities, approves choices, makes the property available, provides documents and decides when a conflict appears between cost, programme and solution. If those decisions remain outstanding, the project can lose a workable front even where labour is available.

For health and safety, confirm what measures, documents and functions apply to the particular project and who undertakes each one. Do not assume that the phrase “turnkey” automatically resolves the legal or contractual allocation of duties. Ask the competent parties to identify, in writing, functions related to safety, coordination, access and site rules.

• Condominium. Inform the administrator about the work, check rules on access, noise, lift use, material movements and working hours. Work to common parts — such as façades, roofs, risers or common structural elements — may require an appropriate approval or resolution.
• Access to the property. Decide who opens the home, where keys are kept, how electrical boards, meters and technical areas are accessed, and what building restrictions exist.
• Timely decisions. Late choices of finishes, equipment, handles, lighting or windows can affect ordering and installation sequences. Keep a decision list with deadlines.
• Formal approvals. Record every change to scope, price, material or programme in writing. A message can form a record if it clearly identifies the work, value, date and approval.
• Documents and payments. Keep proposals, appendices, invoices, communications, photographs and snag lists. Check the work associated with every payment milestone under the agreed terms.

If you are buying a property to renovate, also assess the condition and plans of the condominium. Façade, roof or shared-riser work approved by the building may coincide with the apartment renovation and affect access, costs or decisions.

Energy certificate: a starting point, not a final piece of paper

when available and relevant to the intervention, it can help order improvement decisions before the design and budget are finalised.

The energy certificate is issued within Portugal’s Building Energy Certification System. ADENE explains its role as a source of information on the property’s performance and includes improvement recommendations in its publication on energy certificates and home comfort. During a renovation, those recommendations can be a starting point for discussions about windows, insulation, shading, ventilation and domestic hot-water systems.

Do not, however, treat a recommendation as a ready-to-build specification. The appropriate solution depends on the building, orientation, existing moisture, façade or condominium constraints, budget, available services and the technical documentation for the equipment or materials actually selected. If the design includes a heat pump, windows or insulation, confirm characteristics, installation requirements and maintenance from the selected manufacturer’s documentation rather than general statements.

It is usually more useful to address these issues before walls, floors and ceilings are closed. An energy-related decision made early can be coordinated with pipe runs, technical cupboards, insulation thicknesses and finishing details. The same decision made at the end may require finishes to be reopened or reveal that there is insufficient space, electrical capacity or installation access.

Confirm whether the certificate is included in the proposal, whether further design or study is required, which improvements are actually priced and which documents will be handed over. For more detail, see our article on turning an energy certificate into a home-renovation plan.

Turnkey work at a distance

it can be managed remotely where the contract defines communication, approvals, records, payments and handover.

Living outside Portugal does not prevent a project from proceeding, but it makes document control more important. Before appointing anyone, establish how decisions will be made, how long there is to respond to requests, who validates samples or materials and who can access the property. Regular communication reduces uncertainty, but it does not replace written decisions and clearly allocated responsibilities.

• Regular reports. Agree a reasonable reporting rhythm with photographs, video where useful, completed work, current work, required decisions and identified risks.
• Written approvals. Every change should state what changes, its price, the estimated programme effect and the owner’s or representative’s approval.
• Digital documentation. Use a shared folder or other identifiable archive for proposals, drawings, technical data sheets, communications, invoices, photographs and approved versions.
• Materials and samples. If you cannot see materials in person, request references, photographs, technical sheets and, where necessary, a sample or finish confirmation before ordering.
• Handover through a representative. If you cannot attend, the representative should have appropriate authority for the act they are undertaking. Decide in advance whether they may approve snags, receive keys or sign documents.

Distance does not change planning rules, condominium duties or technical requirements. If the property is intended for short-term letting, check the applicable framework and municipal rules before setting the brief.

How Obra Lisboa works on turnkey projects

At Obra Lisboa, a turnkey proposal should be read as a document setting out the specific scope for the property concerned, not as a generic promise that every service is included. Before appointing, confirm which works, design services, supplies, exclusions and documentary deliverables form part of the proposal, which entity is contracting with you, and how changes, communication, planning procedures and handover are dealt with.

See Obra Lisboa’s services and ask for the scope for your property to be described in the proposal and contract. If you need an integrated solution, compare the document you receive against the points in this guide: survey, design, materials, construction, exclusions, milestones, payments, changes and handover. A clear document is the basis of a verifiable working relationship.

Next steps before requesting quotes

prepare enough information for quotes to be compared by content, not only by their final total.

1. Gather documents. Collect the tax-property record, land-registry certificate, available drawings, photographs, existing certificates and relevant planning information. If condominium minutes refer to planned work, include them in the review.
2. Set priorities. Separate essential, desirable and deferrable work. This helps adjust solutions without losing sight of what is necessary for using the property.
3. Identify constraints. State whether the home will remain occupied, whether there are children or pets, restricted hours, a small lift, stairs without a lift, difficult parking or a need to keep one room operational.
4. Give an investment range. If you choose to share one, it enables materials and solutions to be studied within the available budget. Always ask for options to be identified rather than assuming a lower figure represents the same finish level.
5. Request a technical visit. Photographs rarely show every constraint, particularly in older properties. A visit does not remove all uncertainty but improves the survey.
6. Compare scope and exclusions line by line. Do not compare only the total. Check what each proposal says about demolition, services, waterproofing, materials, kitchen, appliances, planning, waste, cleaning and unforeseen work.
7. Check the IMPIC qualification. Confirm the entity, qualification and class applicable to the value of the work before signing.
8. Build the planning process into the programme. Where it applies, do not set the start date based only on estimated construction duration.
9. Read the contract before paying an appointment sum. Check appendices, payments, variation criteria, suspension conditions, handover and the agreed method of communication.

Frequently asked questions

Is a turnkey project more expensive?

Not necessarily. It includes, or may include, coordination functions that under separate appointments must be carried out by the owner or another professional. A fair comparison requires equivalent work, materials, exclusions, programmes, supplies and change rules. A lower global figure may simply represent a smaller scope rather than a comparable project.

Can a fixed price change during the work?

The price can change where the scope changes, the client chooses a different material or an unforeseen condition requires extra work. The contract should define notification, quotation, written approval and programme effect before work proceeds, except for properly justified emergencies. A “fixed price” without a description of what it covers does not remove this need.

Who handles planning in a turnkey project?

That depends on the contract and the procedure that applies. If the proposal includes this component, it should identify who prepares drawings and submission material, who submits the process, who answers further requests and whether municipal fees, charges or other costs are included or excluded. The applicable planning position must always be confirmed for the specific case.

Can I do a turnkey project without being in Portugal?

Yes, provided communication, approvals, document signing, payments and handover are arranged in a verifiable way. Define reports, response periods, digital records and, if necessary, a representative with appropriate authority. Do not leave approval of materials or changes dependent only on informal conversations.

Does the turnkey model work for shops and offices?

It can work for commercial and office spaces, but the design must take account of the intended use, accessibility, safety, technical services, municipal requirements and other rules applying to the specific premises. Before committing to an opening date, check the procedures and supplies that may affect the programme.
