Stroma is a six-person studio for custom homes, additions, and adaptive reuse. We take twelve projects a year — enough to keep a principal on every one.
Feasibility study $2,500 flat · Full design services typically 8–12% of construction cost — stated in the proposal, never discovered later.
▤ The feasibility fee credits fully toward design if you proceed.
Zoning review, massing options, and an honest cost range — before you buy the lot or commit to the addition. Two weeks, one document.
$2,500 flatSchematic design through construction administration. A principal architect attends every site meeting — that's why we cap at twelve projects.
8–12% of constructionWarehouses, storefronts, odd old buildings. Code path, structural triage, and a design that keeps what made you want it.
Scoped after feasibilityWalk the site together. Define the program, budget, and what "done" means.
Two or three directions, in models you can hold. Pick one, kill the rest.
Materials, systems, and a cost check against budget before drawings harden.
Permit and construction sets contractors can actually bid without guessing.
Weekly site visits by the principal. We answer the builder's phone calls, not voicemail.
"The feasibility study talked us out of the first lot and into a better one. That $2,500 saved us from a $200,000 mistake."

For full services, 8–12% of construction cost depending on complexity — a $600k build runs roughly $48–72k, spread across two years of work. The exact percentage is in the proposal before you sign.
The feasibility study exists for exactly this. $2,500, two weeks, and you'll know the zoning envelope, rough cost range, and whether we'd take it on. The fee credits toward design if you proceed.
Either. We bid to three contractors we trust, or onboard yours — we've co-built with 30+ local builders and keep score on all of them.
Because phase 5 is where buildings get ruined, and it's the phase most firms delegate to juniors. Our cap keeps a principal on your site weekly through construction.
