GRANDS PRIX DU DESIGN – 17th edition
Discipline : Construction & Real Estate : Grand Winner, People’s Choice Award
Categories : Construction / New Single-Family & Mutli-Unit Housing : Platinum Winner
House with garden level and first floor. Ready-to-finish concept with customer finishes.
This is the customer’s last house. He worked all his life to be able to afford it. He still wanted to stay within a budget, so we had to work with several concepts, some more restrained but resulting in a less appealing design, some more ambitious but exceeding the budget. The final project adopts an uncluttered yet impressive architectural signature, a compromise that nonetheless doesn’t seem to be one.
Even though we’re used to doing LEED projects, it’s still hard to aim for Platinum, especially when the location doesn’t provide density and proximity points. But we achieved it by working with our client, who made the right choices in finishes and landscaping.
The adjoining bioclimatic greenhouse also brought technical challenges, given the amount of moisture it can give off, we had to make sure we used rot-proof materials and sealed well between the greenhouse and the garage.
