BIM authoring, generative zoning-to-IFC design, the 80+ module GC portal and development feasibility on one IFC model — offline, no login, no Docker. Add massing.cloud when your team needs hosted models, seats and support.
One platform replaces your
A short tour of Massing — generate, model, coordinate and underwrite, all on one IFC model.

The decisions with the biggest impact happen first, on the back of a napkin, a CAD file nobody else can open, and a spreadsheet that does not match the model.
Testing one more massing option means another afternoon in CAD and a spreadsheet rebuild. So teams test fewer options than they should.
The sketch, the feasibility model and the BIM model are three different files that never agree — and every handoff loses information.
Early budgets get pulled from memory because takeoff cannot start until there are drawings. By then the deal is already priced.
Every record keys off the IFC GlobalId, so geometry, costs, schedule and issues stay in sync from acquisition to turnover.
Stream and federate IFC models in the browser, and author them too — walls, slabs, columns, beams and roofs — with photoreal rendering and sun studies.
Turn a zoning envelope (FAR, setbacks, height) into a complete parametric IFC building — structural frame, unit layouts, façade and cores — then Test Fit unit mix and parking.
Clash detection with exact penetration volumes, IDS validation, BCF issue tracking and 2D drawings — plus point-cloud, mesh and GIS reference overlays.
RFIs, submittals, change orders, daily reports, punch lists, AIA G702/G703 pay apps, CPM & Last-Planner scheduling, TRIR/DART safety, e-signature and COBie turnover.
Development proforma with sources & uses, S-curve, XIRR/NPV, JV equity waterfalls, tri-approach appraisal and MLS/RESO disposition.
massing.cloud hosts it all — managed IFC models, private project databases, team seats, cloud compute and support — so you share a link, not a file.
Subscribe to Home Renovator, Commercial or Enterprise GC (or start Free). Your Massing licence key is issued instantly.
Open Massing in the browser at massing.build/app/ (or the desktop app) and enter your key. massing.cloud provisions your seats, models and databases automatically.
Model in IFC, generate from zoning, coordinate clashes, run the GC portal and underwrite the deal — all on one model, shared by a link.
Draft RFIs, generate scope, level bids and ask model-grounded code-compliance questions — with Claude built in.
A1–A3 embodied-carbon calculation straight off the IFC model, so sustainability is a design input, not an afterthought.
Native Windows, macOS & Linux builds (auto-updating) plus an installable PWA — fully offline, single-project, no account required.
A Dynamo-style visual computational graph and a 37-family parametric library for repeatable, rules-based design.

“We generate a parametric IFC building straight from the zoning envelope, then keep authoring on the same model. The go/no-go conversation happens on day one, not week three.”
Dana R., AIA
Principal Architect“The proforma, IRR and waterfall read straight off the model geometry. Underwriting and design finally live in one place instead of a spreadsheet that never matches.”
Marcus L.
Real-estate Developer“RFIs, submittals, pay apps and the schedule all key off the same IFC model. One platform from acquisition to turnover, hosted so our whole team is on the latest.”
Priya N.
Preconstruction Lead, GC“Federating consultant models and running clash + IDS in the browser means coordination starts on day one — no heavyweight desktop license for every reviewer.”
Tomas V.
BIM Manager“We moved off three subscriptions and a shared drive. Open IFC means no lock-in, and hosting on massing.cloud keeps the whole shop on one source of truth.”
Renée S.
Owner, Design-Build“I generated an ADU from my lot's zoning in an afternoon and sent a clean IFC and PDF to my architect. It paid for itself before the first meeting.”
Khaled M.
HomeownerNo proprietary format. Your data lives in standard IFC, BCF and COBie — the open Massing app has no per-seat licence.
massing.cloud runs the platform — managed models, compute and collaboration — so nobody has to self-host unless they want to.
Isolated project databases per account. Enterprise GC adds SSO/SCIM and a 99.9% uptime SLA.
