Timber Paneling and Built-Ins for Lake Tahoe Homes

The millwork that belongs in a Tahoe house reads as structure. Beams are plain and substantial, mouldings are simple and coped rather than stacked into deep classical cornices, paneling is wide plank or broad frame-and-panel with expressed joints, and built-ins have heavy solid edges and uncomplicated frames. The proportions are heavier than in a Bay Area period house because the rooms, the ceilings and the timber framing are. Species follow the same logic: oak, walnut and cherry with visible grain and character, from the list our main millwork page names, and reclaimed or textured material where the house calls for it. In a mountain-modern house on the North Shore the vocabulary tightens to flush flat panel and clean box beams, but the restraint is the same.

The constraint that governs everything at altitude is movement. A Tahoe house is sealed and heated through the winter, which drives interior humidity very low, and then opened up through the summer; wood shrinks across its width as it dries and swells as it takes moisture back, and the swing here is wider than almost anywhere else we build. So the split between solid and veneered stock is drawn on the shop drawings and followed strictly. Mouldings, stiles, rails, shelf edges, bench tops and anything with a milled profile are solid. Wide flat faces, panel fields and the sides of tall cases are veneered over a stable core, which stays flat through the cycle. Solid raised or plank panels float in their grooves with room to move, and wide plank paneling is detailed with expressed joints that can open and close a hair without showing a gap. Where the design calls for solid plank walls, the boards are kept to widths the species can tolerate and acclimated before fitting.

Ceilings are where the timber vocabulary shows most. On a flat great-room ceiling a coffered grid is laid out from the room’s centerlines so the coffers are equal and the border coffers match, with the beams built as hollow boxes over a ladder of backing fastened to the joists and the moulding inside each coffer kept plain and coped at every corner. On a vaulted or sloped ceiling the right answer is a beamed ceiling that follows the pitch, using the same box-beam construction without the grid. Box beams matter at altitude for the same reason veneer does: a hollow beam built from stable stock stays straight and tight where a solid timber of the same size would check and twist as it dries. Stacked moulding and coffered ceilings are the detail work the founder of our shop trained in.

Built-ins in a Tahoe house do real work: a mudroom with benches, boot bays, hook rails and tall lockers for ski gear, built floor to ceiling and scribed so there is no gap for snowmelt to collect; a bunk room with built-in beds and drawers; a great-room media and bookcase wall; a paneled study. They are furniture-grade casework with proper joinery, shelf spans kept short for the species, and solid lipping on every edge that will take a kick or a ski boot. The room’s base and any cornice are carried across the cases so the built-in and the paneling read as one piece.

Finish is a system built in the shop. Stained work is color-sampled against the whole lot of veneer and solid stock, then sealed and topcoated under controlled humidity; painted work is primed and sprayed; everything is touched up after fitting. The topcoat is chosen for the intense ultraviolet at altitude as much as for wear, because south-facing and lake-facing rooms get strong sun year round. On site, everything is scribed, to walls, floors and ceilings that in a mountain house have settled, racked under snowload or simply were never flat. Our wood movement guide explains the physics behind these choices.
