Mackellar Schwerdt Architects

Based in Lewes, Mackellar Schwerdt Architects creates distinct architectural interventions defined by material contrast, pairing historic timber frameworks and vernacular tile roofs with glossy glazed brick, cylindrical masonry additions, and flush modern skylights across rural conversions and urban developments. This work serves as a precise reference when resolving junctions between historic timber columns and new masonry bases or introducing modern daylight openings into steep, traditional roofscapes.

Interior of a converted barn with exposed timber beams, large bi-fold glass doors, and stone flooring by Mackellar Schwerdt Architects.

Interior of a converted barn with exposed timber beams

A barn conversion interior precedent showcasing the integration of heavy historic timber structures with contemporary dark-framed bi-fold doors and large stone pavers.

What we like about this project
The contrast between the rough-hewn historic wood columns resting on neat brick plinths.

Geometry
Low-ceilinged rectangular room defined by a dense array of overhead timber beams and columns, anchored by a brick wall on the right and large expanses of glazed folding doors on the left.
Facade system
Dark metal-framed multi-panel bi-fold glass doors.
Structural guess
Exposed historic timber post-and-beam frame with load-bearing brickwork piers.
Spatial scale
Intimate ceiling height dictated by historical framing, offset by wide horizontal spans of glass.
Lighting
Bright exterior daylight streams through the large glazed openings, casting sharp geometric shadows across the large-format stone floor.
Atmosphere
Warm and grounded, balancing heavy historic timbers with crisp, light-filled modern apertures.
Environmental context
Rural countryside setting with mature trees and open fields visible beyond the glazed terrace doors.
Spatial experience
A heavy, rustic heritage structure transitions into an open, daylit interior with direct visual connection to the rolling landscape outside.
Composition rhythm
Steady, rhythmic beat of ceiling joists meeting the expansive horizontal datum of the floor and glass.
