Coffered Ceilings and Paneling for Granite Bay Estates

The rooms in a Granite Bay estate house are tall, and a single crown moulding in a tall room reads thin. A stacked cornice solves that: a crown, a frieze board, a bed mould and sometimes a cap, assembled on a backing strip fastened to the framing, which gives the depth and layered shadow lines that make a ceiling line look built rather than applied. The stack is scaled to the ceiling height and the room, deeper in a two-story entry or a formal dining room, lighter in a bedroom, and every element is coped at the inside corners so the reveals are consistent around the room. Casings and base are upgraded with it, because a deep cornice above a thin casing looks wrong; the whole trim package is drawn together. Stacked moulding is the detail work the founder of our shop trained in, and it is the single upgrade that changes these houses most.

A coffered ceiling is the second. The grid is laid out from the room’s centerlines so the coffers are equal in both directions and the border coffers against the walls match, with the beam width absorbing the remainder and the beam depth set against the ceiling height. The grid is snapped full-size on the ceiling and checked against the real walls before any beam is built. The beams are hollow boxes over a ladder of backing fastened to the joists: solid stock where there is a profile to mill, veneered faces where the surface is wide and flat, with the crown or bed mould stacked inside each coffer and coped at every inside corner. Existing recessed lighting almost never lands where the grid wants it, so the lights are re-planned into the coffers or the beams at the drawing stage. In a stained species such as walnut, mahogany or cherry, named on our main millwork page, the veneered faces are sequence-matched so the grain reads continuously across the ceiling; in a painted ceiling the beams are built from poplar and sprayed in the shop.

Paneled rooms follow the same discipline at wall scale. A study or dining room is divided into panel courses that align with the door heads, the window stools and any mantel, with stile and rail widths proportioned to the ceiling height; raised panels are solid and float in their grooves, flat panel fields are veneered over a stable core and sequence-matched from one flitch, and the frieze, cornice and base are stacked from several profiles. The choice between solid and veneered is a structural decision made on the drawings: profiles and edges are solid, wide flat faces are veneered, and the result stays flat through the seasons. Built-ins, a library wall, a media wall in the great room, a bar back in the entertaining space, are furniture-grade casework with proper joinery, shelf spans kept short for the species, and the room’s base and cornice carried across so the casework and the paneling read as one piece.

Finish is a system built in the shop: painted work primed and sprayed, stained work color-sampled against the whole lot of stock and then sealed and topcoated under controlled humidity, and everything touched up after fitting. On a Granite Bay house the topcoat on the glass side of the room is chosen for ultraviolet as much as for wear. And although these houses are newer than the period houses we fit in the Bay Area, they are not square either: drywall corners are rounded or out, ceilings drift, and floors have settled. The scribe allowance is built into every piece and the final joints are cut in the room. Our finish systems guide covers how the finishes are built and why.
