You bought a quinta to restore, and you are rarely on site. WALLNUT designs, licenses and rebuilds Douro wine estates under a single contract, run by one Lisbon team of architects and engineers. Architecture in the Douro has always been a fly-in discipline; what an absentee owner needs is not a local office but one accountable partner who runs the whole restoration in BIM.
Restoring in the Douro
The Alto Douro is a UNESCO World Heritage cultural landscape: schist, terraces, drystone walls and river views come with heritage and PDM constraints that shape what a restoration can and cannot do. We survey the existing buildings (often part-ruined) with reality capture, then design and license the intervention end to end, so the constraints are designed for, not discovered on site.
Remote ownership, real control
Every project runs on a full BIM model, and you approve decisions on immersive visualizations rather than promises. One English- or French-speaking contact owns the answer to every question, from the architecture to the construction site, so progress does not depend on your flights. For a quinta bought as a second home or an investment, this is the difference between a project and a liability.
Wine tourism
Where a quinta becomes a wine-tourism estate (an adega, a small lodge, tasting and event spaces), the integrated model matters more, not less: the building, the process engineering of the cellar, and the schedule all sit under one contract. We assess each enoturismo brief honestly in the feasibility review.
Our work in this area
Every one of these has a page with what we were responsible for, what we were not, and the measurements behind both.

Design-led: selected work
Every project begins as a design problem, not a construction quote: restraint and material honesty over decoration, resolved in full BIM. Under a single design-and-build contract, the studio that designs it also builds it, so the design reaches handover intact. Selected work includes a 470 m² pharmaceutical head office completed in Carnaxide, five floors of offices completed for Conectys in Lisbon and two completed buildings on the Nexzen pharmaceutical campus in Pegões.
Frequently asked
What does it cost and how long does it take to restore a quinta?
It depends on the state of the buildings, the heritage constraints and the program: quinta restoration is typically quoted in indicative ranges per m², which only become a real number against a real survey. See what premium construction really costs in Portugal.
Do you work with foreign owners?
Yes, much of the Douro quinta market is international, and our model (one contract, BIM, multilingual) is built for owners managing a restoration from abroad.
Can you build a wine-tourism lodge or adega?
Yes, as part of the same integrated contract, assessed case by case.
