Furniture sits in a room. Built-in millwork becomes the room. A custom home office is drawn to the walls it occupies — desk depth set to the window sill, shelving to the ceiling rather than stopping short of it, cabling and power run inside the joinery instead of down the back. It costs more than a desk and a bookcase, and it is the difference between a spare bedroom with a desk in it and a room that reads as part of the house.

Facing into the room with a wall behind you if possible — it is more comfortable to work with your back protected, and it puts a controllable background behind you on video calls. Avoid sitting with a window directly behind or directly in front: behind produces silhouette on camera, in front produces glare on screen. Perpendicular to the window is usually the best compromise, giving daylight across the desk without either problem.

A workable single office starts around 8 by 10 feet. A desk wants 60 inches of width minimum and 30 inches of depth, with 42 to 48 inches of clearance behind for a chair to push back and turn. A shared two-person office needs about 12 by 12 feet. Below roughly 70 square feet a built-in desk becomes the only way to make the room work, because freestanding furniture wastes the corners.

In three layers. Ambient light for the room overall, ideally not a single central fixture. Task light at the desk itself, positioned to the side opposite your writing hand so it does not cast a shadow. And a controllable front light for video calls — daylight from a window in front of you, or a lamp bounced off a wall. Screen glare is caused by light behind the monitor, so avoid placing a bright source there.

Most domestic noise arrives through the door and the gap under it, so a solid-core door with a proper seal does more than anything applied to the walls. Beyond that, soft surfaces absorb reflection: a rug, lined curtains, upholstered seating and books on open shelving all reduce echo, which is what makes a room sound bad on a call. Genuine sound isolation between rooms requires insulation and decoupling at construction stage.

Yes, and it is increasingly common — but two desks facing one another rarely works when both people take calls. The better arrangements are back to back, or an L against two walls so neither person is in the other’s camera or line of sight. Acoustic separation matters more than square footage: a shared office where both people are on video at once needs absorption, and ideally a second space one of them can move to.

A dedicated room with built-in millwork generally does, because it reads as a finished room rather than a converted one. A bedroom sacrificed to become an office may not, since bedroom count drives valuation in most markets. The safest approach is millwork that serves as an office but would read equally as a library or a study — which keeps the room legible to a future buyer.

Cost is driven almost entirely by the extent of the millwork, the material and finish specification, and whether electrical and data are being altered. We scope design hours against your actual project and present a proposal before work begins. As with every built-in room, it is significantly cheaper to plan at construction stage than to retrofit, because the requirements are structural and electrical.
