DREAM HOMES PLANNED WEEKLY

From dream home
to development.

WHO IT'S FOR
HOMEOWNERS

Plan your dream home first

You don't need to be an architect. Describe the home you want rooms, budget, style and see multiple layout concepts with real cost estimates before you talk to anyone.

ARCHITECTS

Skip the blank page

Start schematic design from a zoning-clean base. Bring clients multiple costed options at the very first meeting. Spend the fee on architecture, not feasibility arithmetic.

DEVELOPERS

Underwrite with real options

Test what a site can actually carry before you close. Compare yield, cost, and program across every viable massing in one sitting.

FAQ

Questions, answered.

Not at all. Brox is built for anyone with a building project in mind. Describe your dream home in plain language rooms, budget, site and Brox handles the technical side. The output is ready for your architect or builder to take forward.

An address or lot dimensions, a rough budget, and what you want to build. No technical knowledge needed. Brox pulls zoning and site data automatically for supported regions.

Concepts respect setbacks, height limits, FAR, and use restrictions from our code datasets. Final compliance sign-off still belongs to your licensed architect.

DWG and IFC for CAD workflows, plus PDF drawing sets and a structured project brief with the full cost and program breakdown ready to hand to your architect or contractor.

No it replaces the blank page and the guesswork. Homeowners use it to plan before hiring anyone. Architects use it to give clients real options faster. You both arrive at the first meeting knowing exactly what you want.
