The Trillium garage & workshop
A 1,728-square-foot detached garage addition with four-car storage, a dedicated 576-square-foot workshop and an unfinished storage attic. Brickwork, dormer windows and a gabled roof complement the existing colonial-style home.

Room for vehicles and the work you love.
The Trillium project is a 1,728-square-foot detached garage addition in Centreville, Virginia. Designed around four-car storage and a dedicated 576-square-foot workshop, it creates a separate place for parking, tools and hands-on hobbies without changing the main home’s living spaces.
A workshop with a character of its own.
The workshop provides a generous open floor for projects and equipment. A wood-burning fireplace adds warmth and character, while windows bring natural light into the workspace. Epoxy flooring creates a durable, easy-to-maintain surface across the finished garage areas.
Designed to belong beside the original home.
A front brick facade, gabled roof and dormer windows echo the property’s colonial-style architecture. Insulated garage walls and R-8 insulated garage doors complete the practical specification, pairing a coordinated exterior with functional vehicle and workshop spaces.
Storage today. Flexibility for tomorrow.
The attic was deliberately left unfinished as a substantial storage area. The project description identifies potential for a future living-area conversion; these photos show storage, not a completed room or suite. Any future change of use would require its own design and approval review.
