House Extensions
House extensions that transform how you live.
From kitchen-diners to whole new wings, our Portsmouth extension builders deliver beautiful, well-built additions to homes across Hampshire — managed end-to-end.
Single-storey rear
Open-plan kitchen-diner extensions with bifold or sliding doors — a favourite for Portsmouth family homes.
Double-storey
Add bedrooms and a larger ground floor in one project — often more cost-effective per square metre.
Side & wraparound
Unlock awkward side returns and turn them into bright, useable family space.
Garden rooms
Standalone studios and garden offices — a great alternative when planning is tight.
Planning & drawings
We coordinate architects, planning and building control so you don't have to chase paperwork.
Full project management
One trusted point of contact from groundwork to final paint — no juggling subcontractors yourself.
