Building the future of real estate development, in public
Notes on regulatory depth, product decisions, and what we learn running real sites through Keystone.
What 40 US Zoning Codes Taught Us Building an AI-Native FAR Matrix
We're building a verified FAR/zoning matrix across US cities for Keystone. Here's what actually happened when we tried to automate it — and why we chose to leave fields blank instead of guessing.
2026-09-08How Developers Evaluate a New Land Opportunity
A land opportunity is more than a location and a price. Here's a practical India-and-USA framework for deciding which sites deserve a full feasibility pass.
2026-09-08From a Land Boundary to a Development Scenario
A site boundary is not a feasibility answer. Here's the decision chain that turns a parcel into comparable development scenarios, with every assumption visible.
2026-09-08Buildable Area Is Not the Same Question as FAR
FAR tells you how much floor area you're allowed. Ground coverage, setbacks and marginal open space tell you where on the plot you're allowed to put it — and they can bind before FAR ever does.
2026-09-08Buildable Area Is Not the Same Question as Zoning (US Edition)
Zoning tells you what's allowed on a US parcel. Setbacks, parking minimums and FAR-exclusion rules tell you what actually fits — and each varies by city, not by a national code.
2026-08-11US Zoning Due Diligence: A Source Hierarchy
A generic building code does not answer a parcel's permitted use, FAR or setbacks. Start with the local ordinance and official zoning map.
2026-08-11How Early Site-Planning AI Should Be Evaluated
Four questions that separate a real early-stage planning tool from a demo: reproducibility, ground truth, disclosed limits and enforced human sign-off.
2026-08-11FAR/FSI Is Not a Single Number
FSI/FAR is not one figure per zone. Base FSI, premium FSI, TDR and fungible area can change what is actually feasible; Mumbai's DCPR 2034 shows why.
2026-07-23"Code-compliant" is doing a lot of work in that sentence — here's what it actually requires
Every feasibility tool claims its layouts are 'code-compliant.' Almost none of them define what that word is carrying. Here's the honest version, and why we don't use it.
2026-07-17Why real estate feasibility still takes months in an AI decade
Feasibility studies still take 4-12 months and four separate firms. Here's what's actually slow, and what changes when the analysis runs on one live model instead of four disconnected ones.
