How a building grows

Start with one building and add to it

Every wall and roof is a whole number of 15 ft bays. What you add next year meets what you built this year at the same floor and roof lines.

1. Start with a complete kit

A steel factory, 60 × 45 ft: four bays by three. In HO that is about 8.3 × 6.2 in.

2. Add a wing

The first expansion pack, planned to follow the kits, is a lower 45 × 45 ft steel wing. It comes with the junction beam, flashing and roof that join it to the first building.

3. Add another building

A concrete warehouse with dock doors goes on the end. Steel and concrete share one grid, so the walls and roof lines meet.

Two families

Steel and concrete, on the same grid

The family sets the look, the surface detail and the price. Both use the 15 ft bay and the same story height, so they join.

The steel complete kit: a gable-roofed factory with ribbed siding, overhead doors and windows
CAD render

Steel

Ribbed metal siding, trim at the corners and openings, and a gable or lean-to roof. The complete kit is a 60 × 45 ft factory with 32 ft walls.

The concrete complete kit: a flat-roofed tilt-up warehouse with three dock doors and an office entry
CAD render

Concrete

Tilt-up panels with their joints cut in, a flat roof behind a parapet, and dock doors. The complete kit is a 60 × 45 ft warehouse with 32 ft walls.

Walls by the bay

Or order the walls you need

Kits are fixed buildings. Walls are for the building that fits your own track plan: a flat against the backdrop, a longer dock, a wing on a kit you already have.

Sized in bays
A wall is 1 to 6 bays long and 1 to 4 stories tall. Its frame is cut in one piece with the openings.
An opening per bay
Each bay is blank or has an overhead door, a drive-in door, a personnel door, an office entry or a window set. You choose when you order.
Ordered on a form
At launch you pick each bay from a list on the order form. We check the order and email you a render before anything is cut.
Parts to match
Corner posts, roof panels in 15 ft steps and base strips are sold alongside, so a wall can become a building.

Fit study

Fitted to a real track plan

Vandelay is an N-scale roofing plant on a shelf. The rails were fixed first, and the buildings were sized in bays to fit between them and the backdrop.

Planned prices

What it should cost

These are estimates from the CAD and assumed cutting times. They change after the test cuts.

Steel complete kit
Factory, 60 × 45 ft, with roof, corners, base strips, door and window inserts and instructions.

$69 HO, estimated

$52 in N

Concrete complete kit
Warehouse, 60 × 45 ft, with roof, corners, base strips, door and window inserts and instructions.

$64 HO, estimated

$48 in N

Walls
Priced per wall plus per bay-story. A bay-story is one bay of one story.
Steel wall
$5 + $2.50 per bay-story in HO, estimated
Concrete wall
$5 + $1.50 per bay-story in HO, estimated

A 4-bay, 2-story steel wall is 8 bay-stories: about $25 in HO. A door or window in a bay costs the same as a blank one.

N is 75% of the HO price. Waitlist members get 15% off their first order of kits or walls for 30 days after launch.
