The TV presenter and property expert offers straightforward advice on designing extensions that improve flow and functionality at Ideal Home Show Spring 2026 in partnership with Selina Finance.

Nick Knowles shared his top tips for planning a home extension during his appearance at the Ideal Home Show, focusing on how thoughtful design can transform the way a home feels and functions.

Start by understanding your space

Nick encouraged homeowners to approach their property like a designer, starting with what is not working.

“Treat yourself as a designer, really think about your house,” he said. Reviewing an existing floorplan can help identify problem areas, particularly spaces that cause stress day to day.

By focusing on these areas first, homeowners can create a clearer plan for improving layout and usability.

Create a functional core

When adding an extension, Nick highlighted the importance of keeping the central part of the home practical.

“When you put an extension on the back of your house, the best thing to do is turn the middle section into either utility space or bathrooms or kitchens,” he said.

Positioning these functional spaces at the heart of the home helps maintain efficiency and supports the overall layout.

Design for light and living

Nick also emphasised the value of using an extension to enhance everyday living.

“Put the place where you're going to sit and spend the most time with your family in the lovely, light filled extension,” he said.

Focusing on natural light and open flow can help create a space that feels both inviting and connected.

A considered approach to extending

By starting with problem areas, prioritising functionality and designing for light, Nick’s advice highlights how a well-planned extension can significantly improve both the look and feel of a home.
