Eichler Kitchen Constraints

The City of Sacramento’s historic district plan for its Eichler tract states it plainly: radiant floor heating systems that were embedded into the house’s concrete slab foundation, along with much of the plumbing, were characteristic of Eichler homes. The National Register nomination for Greenmeadow in Palo Alto records radiant heating systems as standard and notes that the original floor coverings — cork in the living areas, asphalt tile elsewhere — were chosen respecting the requirements of the radiant heat system. There is no crawl space, no subfloor, and no joist bay to run a new drain through. The Eichler Network’s kitchen feature says the same from the contractor’s side: a lack of subfloor makes electrical and plumbing changes difficult.

What the pipe is made of depends on when the house was built, and it matters. According to the Eichler Network’s history of the systems, the earliest houses from 1950 had copper radiant piping; during the Korean War copper shortage Eichler switched to steel by late 1951 and used it for several years; in the late 1950s the company returned to copper, leaving several thousand steel systems behind with what the article calls a trail of corrosion and litigation. The manifold that distributes hot water from the boiler is usually near it, often in a laundry room, garage or hallway. Copper systems show copper-colored exposed pipe at the manifold base; steel shows green, grey or aluminum-colored pipe; and a magnet sticking to the manifold metal indicates steel.

The distinction decides how much risk a slab cut carries. The Eichler Network reports that copper leaks are generally repairable with current techniques, while a first leak in a steel system can forecast the eventual end of its useful life, and that one radiant specialist will not attempt repairs on steel at all. Where a system has failed, the replacement in the cases the Network documents has been PEX tubing laid in a new slab or a grooved one — a whole-floor project, not a kitchen detail. The practical conclusion for a kitchen is simple. Treat the slab as a finished surface you would rather not open. Keep the sink and dishwasher on the wall where Eichler put them. If the plan genuinely needs an island with a sink, the slab survey, the pipe identification and the concrete work come before the cabinet drawings, and the budget carries them as their own line.

Power is the gentler version of the same problem. An island needs at least an outlet, and the Eichler Network notes that electrical systems in these houses often need upgrades to handle the load of a modern kitchen. A peninsula attached to the existing wall is fed from that wall and needs no floor penetration; a freestanding island is fed from the floor or not at all. That single difference is why so many well-designed Eichler kitchens keep the peninsula the original plan already had.

The Greenmeadow nomination describes the typical house as presenting a relatively blank facade to the street, with clerestory windows on the front and usually floor-to-ceiling, wall-to-wall plate glass along the back wall. The living space is characterized by openness and informality, with a post-and-beam structural system and expansive glass that minimizes the transitions between indoor and outdoor. The kitchen sits at the pivot of those spaces, separated from the living room by a screen wall approximately six feet high. A conventional kitchen’s run of 30-inch uppers on a full-height wall has no wall to hang on.

The design response is to put storage where the house has solid surface: in the base. Deep drawer bases replace door-and-shelf cabinets so that everything is reachable from above without an upper. A pantry column goes against the garage wall or the one full-height interior partition, and an appliance wall on the same partition takes the refrigerator behind a flush panel and the ovens in a column, so the tall storage is concentrated in one bay and the rest of the kitchen stays low. Where an upper is genuinely wanted — over a short run against the screen wall, say — it stays low and shallow, or becomes open shelving, so the clerestories and the glass remain the point of the room.

The glass also changes how the cabinetry is seen. In a conventional plan the kitchen has a front; in an Eichler it has four sides and a top, because it is on view from the living room over the screen wall, from the atrium through the glass, and from the garden. Finished ends, finished backs on a peninsula, and a worktop edge that reads cleanly from across the room are standard rather than upgrades. And because the afternoon sun arrives through a glass wall onto the cabinet faces nearest it, species and finish are chosen to age evenly under ultraviolet light, which the finishes article in this guide covers in detail.

Not every Eichler has an atrium. The Eichler Network notes that the first Green Gables houses of 1950 had no atrium, and the earliest models used front-entry courtyards instead; by the mid-1960s tracts such as Lucas Valley the atrium plan was standard. In an atrium house the court is the open-air space you cross between the front door and the living room, and the kitchen is commonly placed between the atrium and the living room or along the garage wall, as our Lucas Valley page describes. The kitchen may therefore have glass on two sides: the atrium on one and the garden on the other.

Two things follow. First, the cabinetry is seen through the atrium glass as you enter the house, so the elevation facing the atrium is a front elevation, not a back. Second, the atrium is weather. An uncovered atrium admits rain and full sun to the glass beside the kitchen, and the cabinet faces nearest it see more ultraviolet and more temperature swing than any other casework in the house. The finish specification responds to that, and so does the plan: the sink and the most-used worktop want the atrium light, the tall storage does not want the atrium wall.

The atrium is also the one place a cabinetry project can touch exterior review. Enlarging the opening from kitchen to atrium, replacing the atrium glass, or covering the atrium changes something the street or a neighbor may see, and that is exactly what the Greenmeadow architectural review committee, the Lucas Valley association and the city guidelines in Palo Alto and Sunnyvale concern themselves with. Interior cabinetry does not go before any of them. If the scope stays inside the glass line, the project stays a building-permit matter; if it crosses the line, confirm the applicable review before the drawings are final.
