Interiors Designed With the Architecture, Not After It. Sussex & Surrey.

Why Sussex Homeowners Choose ArchEvolve for Interior Design

Interior design that is considered alongside the architectural design, rather than added afterwards, produces spaces that genuinely work. ArchEvolve is MCIAT-chartered with 15 years of experience.

Interior Design: Where Aesthetics and Architecture Disconnect

Interior design that is treated as a separate, later-stage decision often clashes with the architecture underneath it. Structural openings, window positions and ceiling heights are decided during the architectural design phase, and interiors work best when planned alongside them, not after.

Common challenges

How ArchEvolve solves them

How an ArchEvolve Project Works

Every project follows a clear, stage-by-stage process aligned with the RIBA Plan of Work framework.

Feasibility Assessment
We assess planning viability and site constraints before any design fees are committed. This includes understanding how each room is used day to day, not just how it should look.

A Different Standard of Design for Interior Design in Sussex and Surrey

Most practices in the region still work in 2D CAD. ArchEvolve designs interior design projects in Revit and renders in Enscape, so you see the finished space before planning is submitted.
3D Visualisations Included

Every interior design project is modelled in Revit and rendered in Enscape. You see accurate light, materials and spatial quality before a planning application goes in.

Faster Planning Submissions

Drawings produced in a coordinated 3D environment are more complete and less prone to officer queries, which keeps your interior design timeline on track.

Local Planning Knowledge

ArchEvolve has submitted interior design applications across West Sussex, East Sussex and Surrey planning authorities. Your submission is prepared for the specific council from day one.

End-to-End Service

From feasibility through to construction drawings, Alex Page manages every stage of your interior design project personally. No handoffs, no junior staff taking over mid-project.

Interior Design Across Sussex and Surrey

ArchEvolve provides architectural interior design for homeowners across the region, whether as a standalone service or alongside a wider project.

Interior design focuses on layout, materials, lighting and finishes within a space, while architectural design addresses the structure, planning and Building Regulations. ArchEvolve combines both, so decisions made during the architectural stage support the interior scheme rather than working against it.

Cosmetic interior design does not require planning permission. If the scheme involves removing structural walls or altering the layout significantly, Building Regulations approval is needed, which ArchEvolve prepares as part of a combined project.

Yes. Interior design is offered as a standalone service for homeowners who are not extending or altering the structure but want a considered scheme for their existing layout.

Every interior scheme is modelled in Revit and rendered in Enscape, so you can see materials, lighting and furniture layout accurately before committing to a specification, rather than relying on a mood board alone.

Yes, and this is where interior design adds the most value. Combining it with a kitchen extension or full refurbishment means the interior scheme is designed around the new architecture from day one.

The service covers space planning, materials and finishes specification, lighting design, and Revit and Enscape visualisation, delivered either standalone or integrated with a wider architectural project.

ArchEvolve covers West Sussex, East Sussex and Surrey, including Worthing, Horsham, Chichester, Crawley, Guildford and Brighton, with a free initial consultation offered throughout the region.
