Interior Design for Home Extensions

We design extensions that feel like a natural part of your home, both visually and functionally. From space planning and layout through to materials, lighting, finishes and flow, every detail is carefully considered to ensure your new space works seamlessly with the existing property.

Working with homeowners in Harrogate and across Yorkshire, this service is ideal if you’re planning an extension and want to make confident design decisions before work begins on site.

Creating extensions that work as part of the whole home.

A successful extension should feel like a natural part of the existing property. It should improve the way your home works, create better flow between spaces and feel considered as part of the overall design.

We support you through the full interior design of your extension, starting with layout and space planning to ensure the new space functions properly and connects naturally with the rest of your home.

We can introduce trusted builders, architects and contractors from our wider network, recommending professionals based on the needs of your project and their relevant skills, experience and expertise. If you already have your own builder or architect in place, we’ll work closely with them from the early design stages to ensure the interior is considered alongside the wider project.

Our approach.

We take a structured, step-by-step approach, guiding your extension from the early concept stages through to final design. We consider the existing property and new space together, ensuring the extension integrates naturally and works as part of the whole home.

By considering key interior design and build decisions from the outset, and working closely with your architect, builder and other professionals where required, we help reduce the risk of delays, unnecessary rework and costly changes later in the project.

This service is best suited to

  • Homeowners planning an extension

  • Clients reconfiguring existing spaces alongside a new build element

  • Projects where design and build decisions need to be aligned early

  • Homes where the extension needs to feel integrated, not added on
