Test Your Own Garden Building on Any Parcel
Start from a three-story garden massing outline with surface parking, fitted to your parcel, and shape the building to your own footprint. You see how many of your buildings and units the site holds.
How Many of My Garden Buildings Will Fit This Site?
TestFit is real estate feasibility software that generates site plans on your parcel and calculates what they yield. For a custom garden layout, the answer comes down to three things that are hard to judge from a parcel map.
Test the building you already build
If you already build a standard garden building, a generic layout tells you little. Load your own outline and see how many fit.
Parking still sets the count
Surface parking competes with the buildings for the same land. Where the stalls go decides how many of your buildings fit.
Parcel shape decides the rows
Buildings line up along the drive aisles. Parcel shape decides how many fit before parking and setbacks run out.
From Your Parcel to a Deal You Can Underwrite
Start from the custom garden layout your team would build, tune it to your standards, and finish with one model for the site, plan, tabulation and pro forma.

Your parcel and its constraints
- Site boundary: pick the parcel from built-in parcel data with current owner info, draw it, enter metes and bounds, or import a KML/KMZ file
- Setbacks and frontage: front, side and rear setbacks set to the parcel edges
- Zoning: FAR, building and impervious coverage, height limits and parking ratios, pulled in for your parcel so you don't have to dig through the zoning code
- Easements: areas the layout keeps buildings out of
- Site conditions: flood zones, wetlands and topography from Site Intelligence
Every layout starts inside your site's real constraints.

Your product, fine-tuned on the site
- Product: 3-story garden massing from a building outline you define, 11.5 ft floor to floor (34.5 ft), unit counts by unit type
- Site layout: your building repeated along the drives, surface parking
- Your edits: unit mix, unit sizes, buildings, parking and drives
You see the building your team would propose, on your parcel.

A source of truth for the deal
- Site plan geometry: buildings, courts, parking and drives drawn to the parcel
- Tabulation for this product: building sf, dock doors, trailer and car stalls against what's required, site coverage and FAR
- Earthwork: cut and fill for the layout
- Financials: the geometry turned into development costs, revenue and returns
- Shareable results: a link or PDF report for your team, partners and other stakeholders
You know whether the deal works, with numbers to back it.
It’s completely changed the way we think. Instead of parking first, we’re thinking about building first.
Custom Garden Outline Site Planning FAQ
What is the custom garden outline?
A garden layout that repeats one building outline across the site, with surface parking. Edit the outline to match the building you build.
How is it different from the massing study?
The massing study places generic blocks. The custom outline repeats one building footprint that you control.
Can I use my own prototype building?
Yes. Edit the building outline in TestFit to match your prototype, and the layout repeats it across the parcel.
How many buildings fit on my site?
It depends on your footprint, parking and parcel shape. Load your parcel in TestFit with this layout to see the count.
Can I change the layout after it generates?
Yes. Edit the outline, unit mix, parking and drives in TestFit. The site plan and yield recalculate as you go.
