By BUILDER Magazine Staff. Why it worked: Pent-up Detroit-area demand for well-appointed, move-down homes that live large are the key to Treyborne's success. Though not age-qualified, buyers are empty-nesters and active adults for whom single-level living has great appeal. Optional second stories add additional bedrooms for guests.

* Neighbors appreciated attached residential on a property that had been zoned light industrial in a residential area.

* Infill achieved by combining five separate parcels.

* Site borders woodlands and wetlands giving a close-in site an appealing country feel.

* Location within one mile of new expressway exchange means entire metro area is within a 20-minute commute.

* Two basic plans offer second-story options with guest bedrooms.

* Plans are sensible and appealing with a short travel path between garage and kitchen.

* Flexible downstairs room can be den, library, or guest suite.
