Need more room but don’t want to move? An extension can transform your home and give you the space you’ve always wanted.

A home you’ll love

Extending your home is an exciting project and we’re here to help every step of the way. We specialise in bespoke extensions that give you the extra room you need for living, working from home, or entertaining.

Designed for your lifestyle

Every home extension is unique and designed just for you. We approach each project by understanding your requirements and your home’s layout. We’ll work with you to create a home you’ll love.

How It Works

An extension is a big project and at John Lewis Home Solutions we know how important it is to get everything just right. We’ll manage every step, from planning through to the last lick of paint.


Planning your design

Our skilled Architectural Designers will visit your home before creating a detailed drawing of your new extension, tailored to your requirements.

Your build

Your Project Management Team, including an Account Manager and Project Manager, will coordinate your build from start to finish, giving you regular updates on progress.


As part of John Lewis, quality is assured. Your extension is covered by a 12-year structural warranty. We’ll also return six months after your project is complete, to carry out a post-build check.

Is an extension right for your home?

We understand how big a decision it can be, and that there’s lots to consider when planning for your future living space. Our experts will be on hand to talk you through the process and what you can hope to achieve.

What is permitted development?

You may be able to extend your home without applying for full planning permission. We’ll help you understand your Permitted Development rights and whether it covers your project.

Ways to extend your home

Our Architectural Designers will work with you to bring the outside in and create an extension that meets your needs. Whether it’s a side return, dormer or double height extension, we’re here to help.
