description: "Snaptrude launched Snaptrude Agent on Oct 29, 2026 (reported by AEC Magazine), an AI agent inside its browser-based building design platform. Users give it a prompt, brief or drawing, review its proposed plan, then approve or redirect it. Snaptrude says it can generate anything from a handful to hundreds of massing options from a site analysis, convert the chosen one into a detailed LoD 400 BIM model with structure, MEP and drawing sets to a firm's standards, and hand the model to Revit. Its help centre says the site analysis researches zoning and site conditions, cites sources and flags gaps. These are vendor claims, and zoning and code compliance still need a licensed professional. The prompt below helps a buyer, developer or agent run a first-pass feasibility check with any AI before commissioning design work. Use when the user wants help with development site feasibility (business strategy) for a small business."

# Test what a development site can hold before you pay an architect for full drawings: give an AI design agent the site and your brief, have it research zoning, work out the buildable envelope and compare scored massing options

Snaptrude launched Snaptrude Agent on Oct 29, 2026 (reported by AEC Magazine), an AI agent inside its browser-based building design platform. Users give it a prompt, brief or drawing, review its proposed plan, then approve or redirect it. Snaptrude says it can generate anything from a handful to hundreds of massing options from a site analysis, convert the chosen one into a detailed LoD 400 BIM model with structure, MEP and drawing sets to a firm's standards, and hand the model to Revit.

The prompt below helps a buyer, developer or agent run a first-pass feasibility check with any AI before commissioning design work.

## Inputs to collect first
Ask the user for anything below that they haven't already given you. Don't guess missing facts.

- Ress or parcel ID
- Area
- Zone, if known
- E.g. 12 townhouses / a 4-storey mixed-use building with ground-floor…
- Amount
- CHECK
- Your own material (text, notes or data)

## Instructions

Do the task below with the user's inputs in place of each [bracket].

Help me run a first-pass feasibility check on a development site. Site: [address or parcel ID], lot size [area], current zoning [zone, if known], existing buildings [describe]. What I want to build: [e.g. 12 townhouses / a 4-storey mixed-use building with ground-floor retail], target unit mix [describe], budget [amount]. 1) Research the zoning rules that likely apply (permitted uses, height, setbacks, lot coverage, floor area ratio, parking) and cite the official source for each; list anything you couldn't confirm as a [CHECK] item. 2) Work out the rough buildable envelope and maximum floor area. 3) Propose 3 massing options (e.g. maximum floor area, balanced, lowest cost) with storeys, gross and saleable area, unit count and parking for each. 4) Score each option on fit with the rules, unit yield and build complexity, and recommend one. 5) Flag anything that would likely need a variance or rezoning. 6) Write the questions I should ask the city planning office and an architect before going further. This is a screening exercise, not a design or compliance opinion.

## Safety checks (share these with the user)

- Check every figure, price and total against your own records before anything is sent, posted or booked. A person approves refunds, discounts, payments and price changes.
- Anything legal, tax or compliance-related is a first draft for a qualified person to check. It is not professional advice, and clause references and deadlines must be checked against the source.
- Check names, dates, numbers and any claim against your own source material before you use the answer. AI can misread or invent details.
- Say clearly which parts need a person to review or approve before anything is sent, paid, posted or filed.
