The Express–ionis Capsule


The Express–ionis Capsule

The Urban Expressionist Capsule is a compact new build London apartment reimagined for a dynamic young couple. At just 67 square metres, it proves that small-space interior design can be both functional and full of personality — a launchpad for life in the city’s creative currents.

Like many new builds, it came without architectural features to lean on, so decoration takes centre stage. Soft off-white walls set the scene for glossy black furniture, jolts of Yves Klein blue, and flashes of red — every detail a story, every piece of furniture a chapter in the couple’s journey.

Function is never far behind. Distinct zones carve out space for daily rituals, while clever storage keeps clutter at bay. The result? A bold, efficient interior that balances imagination with everyday life — proof that a small London apartment can punch well above its weight.
