Builder grade bonus rooms often sit forgotten above garages, filled with beige carpet and blank walls that resist any sense of purpose. These 30 before and after projects show how homeowners gave these generic spaces clear identities.

From home gyms to craft studios, each room received a focused makeover that addressed its lack of character and function.

From Beige Carpeted Void to Dark Industrial Game Lounge

The original space suffered from pale beige carpet, builder-white walls, and generic brown recliners scattered aimlessly across a cavernous floor plan. Two basic ceiling fans and recessed lighting did little to define purpose or mood. The transformation introduces charcoal-painted coffered ceilings and concrete-look porcelain tile with brass inlay strips that create geometric patterns underfoot. Gray wash board-formed concrete wallcovering wraps the perimeter, contrasting with walnut veneer built-ins that frame backlit display niches.

A regulation pool table anchors the center, flanked by a curved charcoal sectional and a walnut coffee table styled with a copper tray holding whiskey tumblers and a bottle of bourbon.

The poker chip set and design books signal the room’s new identity as a dedicated entertainment retreat.
