Layout-first design, guided by the FLOW Method™
OAT Interiors Surrey based interior design studio
About OAT Interiors
Most interior designers start with how a home looks. OAT Interiors starts with how it works.
Founded by Olya, the studio works with homeowners navigating renovations, extensions and reconfigurations — where the right decisions, made early, shape how a home feels to live in for years to come.
Every project follows the FLOW Method™ — a structured approach that begins with layout and spatial clarity before layering in colour, light and texture. The result is a home that feels considered and effortless. One that works around your life, not the other way around.
Based in Surrey, OAT Interiors works with clients across Hampton Court, Esher, Cobham and beyond — both in person and remotely.
