Know How Much Rear-Load Building Your Site Can Hold
Start from rear-load warehouses in two flexible building types, a smaller one and a larger one, each with its truck court behind it and trucks served from the frontage. You see the building area and dock count before you make an offer.

How Much Rear-Load Warehouse Will Fit My Site?
TestFit is real estate feasibility software that generates site plans on your parcel and calculates what they yield. For rear-load warehouses, the answer comes down to three things that are hard to judge from a parcel map.
How much fits, and in what mix
Lot shape, setbacks and frontage decide how much rear-load building the parcel carries, and how much of it lands in large buildings versus small ones.
Trucks enter from the frontage
With no truck loop around the site, trucks come in from the frontage road and drive past the buildings to reach the rear courts. Where the driveways can go affects how long each building runs.
Cars in front, trailers behind
Offices and car parking face the street while trailer stalls sit in the rear courts. Both have to fit without crowding the buildings.
From Your Parcel to a Deal You Can Underwrite
Start from the rear-load warehouses your team would build, tune them 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.

Rear-Load Warehouse Site Planning FAQ
What is a rear-load warehouse?
A distribution building with dock doors on the rear wall and offices and car parking at the front. The truck court sits behind the building, so the street sees the office side.
Why two building types?
A larger type and a smaller type let the layout use land a single building size would leave empty, so tighter pockets of the parcel still carry building.
How is this different from the rear-load park with mixed sizes?
This layout holds two rear-load building types that each size themselves to the land: a smaller one from 1 to 3 bays wide and a larger one from 4 to 20 bays wide. The mixed sizes layout places buildings in five sizes around a shared internal truck court.
What kind of site works for rear-load buildings?
A visible parcel where the fronts of the buildings can face the street and there is depth behind them for the truck courts. Load your parcel in TestFit with this layout to see how much building fits.
Can I change the layout after it generates?
Yes. Start from this layout, then edit building sizes, docks, rear courts, parking and driveways in TestFit. The site plan and yield recalculate as you go.
