Practically

Tenure, money, code, first steps

Short, in the order it actually happens.

01

Don't buy land first

Land bought before the group, the charter, and the numbers exist becomes a mortgage that designs the building for you. Every case study in the atlas got its land late — often leased, not bought.

02

A core group of 8–15 households

Small enough to decide, large enough to survive departures. Recruit for commitment, not headcount; the mailing list comes later.

03

The charter before the architecture

Money, exit, kids, cars, conflict, commerce — written down while everyone still likes each other. The document is cheap; the fights it prevents are not.

04

Two entities

A community land trust (or an existing one) holds the land permanently; a development cooperative builds and owns the building. Separating them is what keeps the homes affordable past the founders.

05

The Baugruppe model

Residents are the client; the architect runs the process; the 10–20% developer margin stays in the building. This is the single biggest lever in the pro forma — it is how R50 and Spreefeld penciled.

06

Capture vs. build

An existing building (Scenario 3) is faster, cheaper, and teaches governance; a new court (Scenario 1) is the full brief. Strong groups do the first while preparing the second.

07

Single-stair and gallery access: a research item

The gallery-access mid-rise needs egress code work in most US cities. Reform is moving in several states, and the question is live in California — put a code consultant on it in month one, not year three.

08

Retail is pro forma, not amenity

Ground-floor leases — to member businesses and neighborhood ones — carry real rent and real street life. A courtyard block with a dead ground floor is a gated community lying about it.

09

Open-source the brief

Publish the charter, the spec, the numbers, the mistakes. The replication unit is one building; the replication mechanism is the next group not starting from zero.
