General contractor for construction & renovation in Central Portugal
Building or seriously renovating a home in Portugal is a real undertaking — especially if you are still learning the language and the local building process is unfamiliar. We are an English-speaking general contractor based in Fundão, working across Central Portugal.
We write your quote in English so you do not need to translate anything, and we walk you through each phase before we start. Whether it is an extension, a structural rebuild or a full new build, you know what it costs and when it will be finished before the first stone is laid.
What we do
We work for expats and local clients with a serious construction or renovation project. Our strength is non-structural renovation, finishing and converting an old space into a habitable home: masonry finishing, plaster, paint, tiling, floors and non-structural roofs. For structural and larger works — new foundations, load-bearing structures, the shell of a new build, or structural reinforcement — we work together with a licensed local empreiteiro and an architect/civil engineer who provide the design and sign-off. We then carry out the building and finishing work within that framework. For the finishing trades (plaster, paint, tiling) we have a regular crew we have worked with for years.
- Non-structural renovation and finishing
- Annexes, garages and outbuildings (structural part in partnership)
- Shell, foundations and masonry — together with a licensed empreiteiro/engineer
- Roofs and floor structures — structural part with engineer sign-off
- Coordination of plumber, electrician and plasterer on our own site
Service area
Our base is Fundão. We regularly work in Covilhã, Castelo Branco, Belmonte, Penamacor and Guarda. Further out (Sertã, Oleiros, Sabugal) is also possible, but we account for extra travel time in the quote. Travel is always listed separately so there are no surprises at the end of the job.
Legal and transparent
Registered as a sole trader (trabalhador independente) in Portugal — NIF 309729211. For larger construction projects that legally require a registered empreiteiro or sign-off by an engineer in Portugal, we work together with a licensed local contractor and an architect/engineer who deliver the project legally; we carry out the building and finishing work. That means you will not run into problems during a future sale, valuation or mortgage application. Every invoice carries our Portuguese NIF so the work is properly accountable for tax purposes.
How it works
First we visit the site for an assessment, usually within a week of your request. You then receive a written quote with phases, materials and timeline. During the build we stay in touch by WhatsApp and send weekly progress photos. Material costs are itemised with receipts so you can see exactly where your money goes. At handover we walk the site with you, and only then do we close the final payment milestone.
