Mia Karlsson Interior Design

Based in London, Mia Karlsson Interior Design shapes loft spaces and residential suites through a synthesis of tailored architectural joinery, continuous tile surfaces, and vibrant chromatic framing softened by sculptural, organic elements. This portfolio serves as a strong reference when specifying flush-integrated cooktops, executing continuous wall-to-floor bathroom tiling, or aligning bespoke storage with sloped overhead rooflines.

Interior stair landing featuring a vibrant pink planter balcony and a burgundy spiral staircase by Mia Karlsson Interior Design.

Reimagining a Highgate loft through the power of joinery

An interior precedent for residential loft circulation that uses custom joinery, bold pink planter boxes, and a contrasting spiral stair to animate neutral white surfaces.

What we like about this project
The planter boxes cantilever boldly off the mezzanine edge, matching the railing color to form a unified architectural band.
