Coordinate the build, not the chaos.

Marketplace
Vendors get discovered. Architects find the right trade.
Coordination tools stop at the drawing. 5Bloc lists contractors and vendors by trade and city so an Austin storefront job finds a listed millworker — and that millworker gets found by practices running work here.

FAQ
The short answers to the honest questions.
One workspace for everyone on a build project. Drawings, RFIs, and updates — instead of email and scattered folders.
Yes. The waitlist is free for architects, contractors, and vendors. Early architects get their first three projects free at launch.
After launch, the architect's practice carries the subscription. Everyone invited to a project stays free.
Use the contractor or vendor buttons at the top of the page. Listing is free — we will email you when onboarding opens in your city.
5Bloc is built for architect-led projects, not GC-led enterprise programmes. Invited contractors and clients stay free, IBC and permit tracking is in the product, and there is no per-seat tax for the people you already work with.

Under 10 minutes per project. Create the workspace, upload drawings, invite the team. No admin, no IT ticket, no implementation consultant.
Clients open a link in the browser — no app to install. Contractors get the latest drawings automatically when you publish a version, instead of hunting through email. The architect runs the project; everyone else just sees what they need.
Projects are private to your organisation. Access is role-based. Files sit in encrypted object storage. We do not sell project data. You can export drawings, RFIs, and records in standard formats at any time.
You can export anytime — PDFs, drawings, and project records in standard formats you already use. Your files stay yours. We would rather you leave with a full archive than feel locked in.

Practices already on the beta
Built by architects, trusted by studios.
“I've managed 14 projects. Every single one ran on email threads I couldn't search and Excel sheets nobody trusted. 5Bloc is what I wished existed when I started my practice.”
Elena M.
Principal Architect, Austin
“The client portal is the first thing I show a homeowner. They see progress in plain English instead of forwarding them a 40MB DWG.”
Maya R.
Principal Architect, Brooklyn
“RFIs used to die in email. Now they sit on the drawing they refer to, and the contractor actually answers them.”
James V.
Studio Lead, Denver
Why we built this
Two people, one shared frustration.
Parth trained as an architect at SPA Delhi. On every job, the work itself was never the hard part — finding the latest drawing, chasing an RFI, and explaining progress to a client across a dozen email threads was. Haet builds the product. Together we built 5Bloc so architect-led teams can run the project in one workspace, without asking contractors or clients to install another app.
