Mid-century modern tract homes: what the originals sell for today

8 September 2026

In 1957 a buyer could walk into the sales office at Twin Palms Estates on the south side of Palm Springs and put a deposit on a new architect-designed house, with a swimming pool, for under $30,000. The plan was 40 feet by 40 feet, post and beam, with glass where a wall might otherwise have gone. William Krisel had drawn it for the Alexander Construction Company so that it could be flipped, rotated and topped with a different roofline on every lot, which is how ninety near-identical houses managed to read as a neighbourhood rather than a barracks.

Nearly seventy years on, those houses are still there, and so are their cousins in Phoenix and Portland. The interesting question for anyone who cares about how modernism actually got built is not whether these tracts are admired. They are, to the point of cult. The question is what they cost now, in markets where a new house is built from a very different set of assumptions.

The postwar builders who carried modernism into the tract market shared a single insight: the economies of mass production did not have to yield a Cape Cod. Visit Palm Springs credits George and Robert Alexander, a father and son who were developers rather than architects, with more than 1,200 residences across the Coachella Valley between 1955 and 1965. Their method was to hand the drawing board to Palmer & Krisel and then engineer the construction process so tightly that good design cost less per square foot than the conventional alternative. Twin Palms proved the point. Racquet Club Estates, Vista Las Palmas and the rest followed.

The houses were small by today’s standards. Most of the early tracts came in around 1,200 to 1,600 square feet, with the pool and the mountain view doing the work that extra bedrooms do elsewhere.

That modest footprint matters when you look at the market. Movoto’s data puts the Palm Springs median home price at $549,000 for July 2026, working out to roughly $333 per square foot. Palm Springs is a resort city with a large second-home and condominium stock, so the citywide figure is a blended one, and an intact Alexander in a sought-after tract will generally list above it. Even so, the premium is measured against a base that an ordinary professional household can approach. The custom desert modern houses by Neutra, Frey and Williams live in a different universe entirely. The tract houses, which borrowed their vocabulary and shed their budgets, do not.

For context, the national median sales price of a newly built house was $393,800 in July 2026, according to the Census Bureau. New-build pricing has been drifting down for over a year as builders discount to move inventory, which means the gap between a sixty-year-old modernist original and a brand-new production house is narrower than the cultural distance between them would suggest. Buyers in these three cities are not choosing between a bargain and an indulgence. They are choosing between two houses of broadly similar cost and radically different design intent.

Phoenix tells the story from the architect’s side rather than the developer’s. Ralph Haver was not building anything himself; he was designing for whoever would hire him, and in the early 1950s that was nearly everyone. Modern Phoenix, the volunteer archive that has done more than any institution to document the city’s postwar housing, records that a single Sunday newspaper in 1951 advertised three separate Haver-designed tracts for three different builders on the same page. Marlen Grove, built by Perry-Brignall from 1952 on a former citrus grove in what is now Uptown, is the one enthusiasts point to first. Four models, flipped and rotated along the street, low-pitched gables, clerestory glazing, integrated carports, and a claim by the builder to have pioneered reinforced masonry construction at mass scale.

Haver’s firm went on to design something in the region of 20,000 tract homes across Arizona, New Mexico and Colorado. Many have been demolished or remodelled beyond recognition. The surviving pockets, Marlen Grove, Windemere, Starlite Vista, Northwood, are now among the more expensive small houses in central Phoenix, and the reason is that their scarcity is architectural rather than geographic.

Movoto’s market data shows the Phoenix median sale price at $475,000, and the Haver neighbourhoods near Bethany Home Road sit comfortably above it. A 1,200 square foot Haver competes with, and frequently beats, a 2,500 square foot house of 2005 vintage a few miles north. The market is pricing the design, not the volume, and that inversion of the usual rule is the clearest evidence anywhere in the United States that architect-designed tract housing has held its value on architectural merit.

Portland is the smallest of the three stories and in some ways the most instructive, because it is the one where the supply is most finite. Robert Rummer had no architecture degree. His wife toured Eichler’s Rancho San Miguel tract in Walnut Creek in 1959 and came home convinced; Rummer went to see Eichler, came back to Oregon, and started building. Restore Oregon puts his output at 750 homes between 1959 and 1975, of which around 300 were in the modernist idiom before market and code pressure pushed the company toward conventional ranches. Twenty-nine of them sit within the Oak Hills historic district in Washington County, listed on the National Register in 2013 as the first mid-century modern district on the West Coast. Rummer died in January 2025 at 97, and the tours of his houses that Restore Oregon runs still sell out.

Three hundred modernist Rummers, minus attrition, is not a large stock for a metro of two and a half million people. A search of homes for sale in Portland in any given month turns up far more 1990s infill than 1960s post and beam. Movoto’s August 2026 figure for the city puts the median list price at $525,000 and about $310 per square foot, and Rummers, when they surface, tend to sit above that line and go quickly. The atrium plans, the radiant floors, the full-height glazing at the rear, all of it was specified as a selling point in 1965 and all of it is why the houses still sell now.

What unites the three cities is a pattern that architects should find both flattering and slightly uncomfortable. Every feature that makes these houses desirable today was originally a cost-control device. Krisel’s flippable plan existed to cut drafting and framing time. Haver’s four-model rotation existed so a builder could pour identical foundations. Rummer’s post and beam was cheaper to erect than a stick-framed two-storey. The glass walls saved on interior finishes. The carport saved on a garage. Modernism in the tract market was not a stylistic choice imposed on a budget; it was what the budget looked like when a competent designer was allowed to spend it.

Today’s production builders control cost by the opposite means. Bigger boxes, fewer openings, plans that do not rotate because there is no reason to look at them from the street. The result sells, and at a national median under $400,000 it sells for less than a Rummer or an Alexander. But the older houses are still holding a premium in three markets that have every reason to have forgotten them, and it is worth asking what a production builder would have to do to earn that kind of loyalty sixty years from now.
