Garnett Architecture

Based in London, Garnett Architecture pairs substantial masonry massing with precise, rhythmically arranged metal and precast detailing across commercial and mixed-use developments. This portfolio serves as a strong reference when designing street-level office thresholds, detailing ornamental grilles within interior reception spaces, or articulating modern fenestration against historic masonry facades.

Aerial view of a contemporary dark metal and green roof rooftop extension set atop a classic white historic building in London by Garnett Architecture.

26 King Street Covent Garden, London WC2

An aerial precedent for sensitive rooftop extensions, combining a dark metal-clad, curved-glass pavilion and green roof atop a classic historic facade.

What we like about this project
The curved corner glazing softly mirrors the rounded geometry of the underlying historic parapet.

Geometry
A stepped-back dark metallic pavilion with curved corners sits symmetrically atop the rigid vertical rhythm of an ornate historic masonry facade.
Facade system
Curved glazed curtain wall with dark metallic framing and integrated louvered penthouse.
Structural guess
Lightweight steel framing or timber superstructure added to existing masonry bearing walls.
Spatial scale
Medium-scale urban insertion; a single-story rooftop pavilion adding mass to a multi-story city building.
Lighting
Direct daylight casting sharp shadows across the white historic cornice and dark rooftop louvers.
Atmosphere
Clean, deliberate architectural integration contrasting old masonry with modern metallic lightness.
Environmental context
Dense urban historic context surrounded by abstracted or muted neighboring masonry volumes.
Spatial experience
The view emphasizes the contrast between heavy historic massing below and lightweight, transparent rooftop habitation above.
Composition rhythm
Horizontal banding of the green roof and louvers counterpointed by the vertical punched windows of the historic base.
