US studio Lehrer Architects has completed Loma Verde, a supportive housing development in Los Angeles built on what Dezeen describes as an "extremely narrow" site. Writing on 27 August 2026, Jenna McKnight reports that the project houses once-homeless residents in a building defined by a slender footprint, with stucco walls carrying deliberate splashes of colour. It is a modest brief on an awkward parcel — and precisely the kind of project where the discipline shows, because a narrow site removes almost every escape route a designer normally relies on.

The arithmetic of a slender plan
Slenderness has a price and a dividend, and both are geometric. Take 2,000 square feet of floor area. Arranged as a square, the plan measures roughly 45 by 45 feet and carries about 179 linear feet of exterior wall. Arranged 20 feet wide, the same area stretches to 100 feet long and carries 240 feet of wall — roughly 34 per cent more envelope for the same rooms. Every additional foot is another foot of foundation, another foot of insulation, another foot of flashing and sill and junction. Narrow buildings are expensive per square foot for reasons that have nothing to do with taste.
The dividend arrives in the same equation. In a 20-foot-wide plan, no point in the building sits more than ten feet from an exterior wall. Daylight reaches everything. Cross-ventilation works, because air entering one long elevation has a short, unobstructed path to the other. Deep, fat plans — the default of the American custom house — buy cheap envelope and then spend the savings on artificial light, mechanical cooling and rooms nobody uses because they have no window. The narrow plan makes the opposite trade, and it is usually the better one.
There is a third consequence that rarely gets discussed in design coverage: lateral structure. A long, thin building has very little wall available in its short direction, and seismic force does not care about aspect ratios. On a narrow site, the few cross-walls you have must do a disproportionate amount of work, which pushes the plan toward stiff, continuous, well-anchored elements rather than the perforated open-plan glass boxes that wide lots permit. Slenderness disciplines the plan from below.
Why this matters on the Westside
Los Angeles has run out of easy lots. What remains in the desirable basins and canyons is residual: slivers left by old subdivisions, parcels squeezed by side-yard setbacks, hillside strips where the buildable envelope narrows as the grade steepens. Buyers with the budget for a serious house increasingly find themselves looking at land whose only defect is width — and rejecting it on instinct, because the mental model of a luxury house is still a wide, forward-facing volume with a lawn in front of it.
That instinct is worth interrogating. The Mediterranean tradition that half of Los Angeles borrows from was built almost entirely on constrained urban parcels: houses one or two rooms deep, organised along their length, lit and ventilated from both flanks, with the open space held inside rather than displayed at the street. Loma Verde is not a villa and does not pretend to be, but the manoeuvre is the same — accept the width, work the length, and use colour and surface where volume is unavailable. Lehrer's colour-blocked stucco is doing real architectural work here: on a building with two long elevations and almost no depth, the facade is the entire compositional budget.
For anyone commissioning a house on a difficult Westside or hillside parcel, the practical lesson is that the width of the lot determines the structural system, not the style. A 20-foot-wide house wants continuous mass in the short direction and a rigorous rhythm of openings on the long ones. Decide that first, and the plan resolves. Decide the elevation first, and the engineer will spend the next six months undoing it.
What narrow sites will teach the luxury market
The most instructive projects in Los Angeles right now are rarely the largest ones. Constrained-budget, constrained-site work like Loma Verde tests assumptions that generous commissions never have to confront — how thin a wall can be, how far daylight really travels, how much a facade can carry when there is nothing else. Those answers travel upward. As the supply of wide, flat, buildable land continues to thin, the houses that hold their value in this city will be the ones whose geometry was chosen deliberately rather than inherited from the lot next door.
