Architects & Turnkey Construction in Comporta
A Comporta house is owned from afar and built on the ground: exactly the problem our model solves. One Lisbon team designs, licenses and builds it under a single contract. Answer within two business days.
Single design-build contract
21 architects and engineers, full BIM
Licensing handled end to end
Answer within two business days
Comporta projects are owned remotely and built locally: that is exactly the problem our model solves. WALLNUT designs, licenses and builds under a single contract, run by one Lisbon-based team of 21 architects and engineers, so a house on the Alentejo coast doesn’t require you to manage architects, engineers and builders from three time zones away.
Building in Comporta
Comporta, Melides, Carvalhal and the Alentejo coast carry specific constraints: protected landscape, plot-by-plot building rules, municipal licensing in Alcácer do Sal or Grândola, and a construction market under heavy demand. The feasibility review we run before any design tells you honestly what your plot allows, how long licensing realistically takes, and what the budget frame looks like.
Remote ownership, real control
Every project runs on a full BIM model with reality capture, and you approve decisions on immersive visualizations, not on promises. One English-speaking contact owns the answer to every question, from the architecture to the construction site. Progress doesn’t depend on your flights.
One contract
Design-build means the team that designs your house is contractually the team that builds it. For second homes this is the difference between a project and a liability: budgets owned by the people who set them, a calendar that survives contact with licensing, and accountability that doesn’t fragment when something goes wrong.
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 two completed buildings on the Nexzen pharmaceutical campus in Pegões, a 470 m² pharmaceutical head office completed in Carnaxide and five floors of offices completed for Conectys in Lisbon.
Frequently asked
Do you cover the whole coast?
Comporta to Melides and the surrounding municipalities, managed from Lisbon. See also our Lisbon practice and architects in Cascais and Estoril.
What does building here cost?
Premium coastal construction carries a meaningful premium over city benchmarks: logistics, materials and market demand. We published an honest breakdown: the true cost of premium construction in Portugal.
Can you take over a stalled project?
Yes, “I’m mid-construction and stuck” is one of the four intake paths. We assess the state of the work and tell you what it takes to finish it properly.
