Can cabinets be built to fit sloped ceilings, beams and awkward corners?

Yes — this is the main reason to choose custom over modular furniture. We cut carcasses and doors to scribe against sloping ceilings, exposed beams, pipe ducts and out-of-square walls, and design corner units with carousel or Le Mans fittings so dead corners become usable. Provide photos plus a dimensioned sketch of the awkward area and we will solve it in the drawing stage.
