DESIGNED TO DRIFT

Bespoke floating homes where brutalist steel meets poured-concrete warmth

Every Berth vessel begins as 12mm Corten steel plate — cut, bent, and welded by hand in our Rotherhithe yard. The hull is not a shell; it is the architecture. Each weld seam is a structural decision. Each angle is drawn to catch river light at a precise hour.

The armor
hides warmth.

Step through the hatch and the brutalist logic inverts. Poured concrete countertops. Hem fir joinery. Panoramic river glass that turns every mooring into a living painting. The galley looks through the helm window at whatever canal you've chosen to call home tonight.

Poured Concrete

All countertops and feature walls cast on-site, each unique

River Glass

Floor-to-ceiling triple glazing, thermally broken steel frames

Radiant Floors

Hydronic underfloor through polished concrete slabs

Helm Windows

Full-width glazing from galley to bow — your river, framed

I've collaborated with naval architects who think in displacement and designers who think in rooms. Berth is the first studio that thinks in both simultaneously. The Blackfriars vessel is the most resolved project I've ever been associated with.

Blackfriars I — 24m

The terrace
above the city.

Every vessel carries a rooftop terrace — some planted with sedum, some laid in Corten grating that will weather to the same patina as the hull. At night, London becomes a reflection. The river returns the sky.

Your river.
Your hull.

We take on four commissions a year. Each vessel is a single project — no parallel builds, no compromised attention. The process takes fourteen months from brief to first night. The waiting list is how we maintain the quality that earned it.

01

Brief & Mooring

A two-hour conversation about how you live on water. We identify your mooring, your light, your river.

02

Hull Design

Our naval architects draw the displacement. Our interior architects draw the life inside it. One studio, both disciplines.

03

Build & Survey

Construction in Rotherhithe. Marine survey at every structural stage. Delivery to your mooring.

04

First Night

We hand you the keys at dusk. The river does the rest.

The waiting list
opens in March 2026.

Three enquiries are already under discussion. If you are reading this, you found us early.
