Defining the Buildable Program\n\nBefore you look at a single parcel, define what you want to build: use type, units or square footage, and target market. The program drives every downstream decision.

Going Deeper (Intermediate)

The program is what you'll build — product type, number of units, sizes, density, mix, and amenities — derived from the HBU and the market. It turns the vision into a buildable, countable plan that the pro forma can price.

Advanced / Pro-Level

Get the program right with engineering and market input:

• Density (units/acre, FAR) and a yield study / test fit by a civil engineer to confirm how many lots/units the site actually holds after roads, setbacks, stormwater, and open space.
• Product mix and sizes matched to market demand and absorption (how fast it sells/leases).
• Parking ratios and phasing. The yield drives the pro forma — overestimate it and the whole deal is wrong. Engineers' test fits keep you honest.

Practice Challenge

You assume 100 lots on a 25-acre site (4/acre), but the civil engineer's yield study returns only 78 after roads, setbacks, and a detention basin. Why does this matter enormously? (Answer: the revenue (and the price you can pay for land) is based on yield — 78 vs 100 lots is a 22% revenue cut that can flip the deal from profit to loss; a real yield/test-fit must replace the napkin density before you commit.)

In Practice

A developer falls in love with a parcel, then forces a project onto it that doesn't fit the market. Defining what you're building first — and matching land to it — avoids that trap.

Common Mistakes to Avoid

• Buying land before defining the project
• Building a program the market doesn't want
• Ignoring the target customer

Takeaway: Define what you're building before you look at land; the program drives every later decision.
