Compare conceptual subdivision layouts

The challenge

A first lot-yield estimate usually comes from one hand sketch, so the trade-off between orientation, lot width and open space is never actually explored.

The scenario

A civil engineer is asked for three preliminary concepts on a 42-acre site with 7,500-square-foot minimum lots, public roads, a stormwater reserve and 15% open space.

What goes in

Instruction or rules

Minimum lot area and frontage, right-of-way and pavement widths, setbacks, open space and reserve targets.

Constraints

Mapped flood hazard and wetlands, and any no-build easements, avoided by the solver.

What you can ask

Illustrative prompts. Results depend on your own data and are not deterministic.

• “Create three preliminary subdivision concepts using 7,500-square-foot minimum residential lots, public roads, stormwater reservations and 15% target open space.”Copy

How Clearception approaches it

How the work is structured. Each step shows what its output is grounded in.

1. 1

   Read the instruction

   Observed

   The instruction is read deterministically; anything missing is asked for.

2. 2

   Solve layouts

   Observed

   Streets and lots are laid out across orientations and lot widths, and every lot is checked.

3. 3

   Compare

   Estimate

   Lot yield, gross-to-net, street length, open space and impervious cover side by side.

What you get

The shape of what comes back — not a promised result.

• Concept comparison table

  Estimate

  Yield and infrastructure quantities per concept, with violations and assumptions.

• Plan sheet

  Observed

  A true-scale PDF sheet with lot numbers and a lot area schedule, stamped conceptual.

Why it matters

Explore before you commit

Several layouts in minutes instead of one sketch.

Reproducible

The same inputs always produce the same coordinates.
