Renew, Revitalise, Renovate

Here at Eco Home Extensions, we work to create a bespoke addition that meets your needs, whether you’re in Portsmouth, Southampton, Fareham, Havant, Chichester, Guildford or the surrounding areas. We know the investment of time and money that goes into a major remodel like an extension.

That’s why we like to keep it simple. We’re part of the larger Eco Group. Meaning you can have just one contractor for your electrical, window, roof and solar needs if you need to combine them. We’re one of five individual subdivisions, run by specialist teams.

With our dedicated builders, choosing to build an extension can improve the value of your home by as much as 20%. You don’t have to take our word for it. Contact an estate agent or surveyor to assess the current value of your home and ask what value an extra room can add.

The choices for your new extension are endless. Talk to us about your current architectural style, floor plan, and potential uses of your addition so that we can help you plan. Eco Home Extensions will help you plan, whether you’re looking for a new kitchen, bedroom, or loft conversion.

Attractive Extensions

One of the benefits of an extension is improving your home’s natural light. Create a dynamic centrepiece in your home by adding a striking feature like a roof lantern or a bifolding door. Plus, you can add windows to your roofline to improve the lightness of your home.

Stone, Brick or Timber Exterior

Matching the architectural style of your property is important. Choose the façade that enhances the beauty of your property. Eco Home Extensions provides options such as: classic brick, stately stone, or rustic timber. If you live in a conservation area you may need to look up what materials are allowable.

Plus, you can talk to us about a timber frame extension or brickwork. We can ensure that your addition is built swiftly, even in poor weather with timber frames. Now you don’t have to wait for the summer months to get the addition you desire.
