The feasibility verdict
A clear answer from a site and a brief — buildable area, unit mix, and whether the deal works, before you commit a week to it.
Design + feasibility app · For architecture firms & developers
Lyra is a desktop app that turns a site and a brief into massing, a zoning-checked feasibility verdict, and a lender-ready pro forma with levered IRR and equity multiple. Know if it pencils before you draw a line.
10 free credits · No card required · macOS & Windows
Sample Lyra output — generated from one address.
You sketch the massing in one tool, then wait days for someone to tell you it doesn't pencil. Lyra runs the numbers as you design — so you walk into the meeting knowing the IRR, the equity multiple, and exactly what makes the deal work, with every assumption on the table, not buried in a black box.
One run, the whole story
A clear answer from a site and a brief — buildable area, unit mix, and whether the deal works, before you commit a week to it.
A real pro forma with debt, absorption or lease-up, and a returns section. Sell-out or hold — the model is mode-aware and lender-ready.
FAR, height, and coverage pulled for your parcel — built-in tables for NYC, Chicago, SF and LA, with live lookup by address, or enter the controls yourself for any other market.
Explore ranked massing schemes, then let Lyra grid-search the one that pencils best — and adopt it into the model in a click.
Turn the winning scheme into a photoreal render to put in front of a client or a lender — the design and the deal, on one page.
Export the investor memo as a PDF, the model as Excel, and a one-pager for the client — branded and ready to send.
How it works
Type it in plain language or load a parcel. Lyra fills the form — zoning, unit mix, costs — and tells you what it assumed.
Generative massing, zoning checks, and a full pro forma with IRR and equity multiple — in one pass.
Investor memo (PDF), pro forma (Excel), client one-pager and a photoreal render — ready to send.
Why trust the numbers
Lyra runs a fully transparent pro forma — standard levered-return methodology (IRR, equity multiple, yield on cost) with every assumption shown and editable. Zoning comes from published municipal data for NYC, Chicago, SF and LA, with live lookup by address. You can check and change every input, so the result is yours to stand behind — not a number from a black box.

Yes, as a first read — and a defensible one. Lyra pulls real zoning data and runs a fully transparent pro forma where every assumption is shown and editable, so you can defend the number in the room. Built-in city tables are clearly labelled starter data; live address lookup is available for the covered metros. Like any feasibility study, it's the start of underwriting, not the end — verify against the municipality and your own model before you close. Lyra gets you to that decision in minutes instead of days.
No. You describe the site and brief in plain language — or drop in an address — and Lyra fills the form, shows every assumption it made, and runs the feasibility. There's no CAD to relearn and nothing to rebuild; your first verdict takes minutes, not an afternoon.
One credit is roughly one photoreal render or one feasibility run. Plans include a monthly allowance; top-ups never expire.
Both. Lyra is a native desktop app for macOS (Apple silicon & Intel) and Windows 10/11.
Your projects are yours, and we don't sell your data. Lyra processes renders, zoning lookups and feasibility on our servers to do the work; every export — Excel, PDF — is a standard file you keep, even if you stop subscribing. See the privacy policy for details.
