No tract. No comparables. No pattern.

Alongside the tract work, Eichler Homes built individual houses on individual lots — for clients, on land that was not part of any subdivision. A handful of these sit in South Los Altos and Los Altos Hills, and they span the 1950s through the 1970s — almost the entire arc of the operation, from the early Anshen & Allen years to the last work before Joseph Eichler died in 1974. They share the architecture and none of the context.

Because they were built one at a time, they vary far more than tract houses do: bigger lots, altered plans, custom glazing, different rooflines, occasionally an architect other than the usual Eichler office. Two customs a mile apart may have almost nothing in common beyond the beams.

A custom Eichler on a Los Altos Hills acre is routinely valued against Los Altos Hills houses of similar size — which is to say, against houses with none of its architecture — or against Fallen Leaf Park tract Eichlers, which have none of its land. Both approaches produce a number, and both numbers are wrong, usually in opposite directions.

The land and the architecture have to be valued separately and then reassembled. In the Hills the site frequently carries most of the value, which raises a question most owners have never been asked directly: is the house an asset on this lot, or is it in the way? For an intact custom Eichler the honest answer is almost always that it is the asset — but it needs to be argued with evidence, not asserted.

That argument is what a listing here lives or dies on, because the buyer who pays the architectural premium is not the same buyer who is shopping Los Altos Hills by the acre.

Customs are not flagged in any public dataset as Eichlers. They do not sit in a named tract, the assessor does not record the architect, and portal listings frequently describe them as “mid-century” or miss it entirely.

We keep our own record of the ones we have identified. If you own a house you believe is an Eichler and it is not in Fallen Leaf Park or on Parsons Way, we can usually confirm it from the frame, the glazing details and the roof structure.
