House extensions built in Tonbridge and across Kent, Surrey and Sussex - support from planning to completion

Single- and double-storey builds. Planning to completion support. Rear, side and wraparound options

Our professional edge 

One team seeing the job through

We manage your project from the planning stage to completion. That keeps communication clearer and helps avoid loose ends.

Built for real family life

We shape new space around the way you use your home now. That gives you rooms that earn their keep every day.

Less upheaval while work is underway

We plan each stage carefully to reduce disruption around your routine. That matters when your home still needs to function during the build.

More room without leaving the home you love

House extensions can change the way your home works day to day, giving you the extra room you need without the cost and stress of moving. Nationcare Construction Limited completes single-storey, double-storey, rear, side and wraparound projects, shaping each build around how you actually live. 

 

We've spent 50 years delivering building work, and we manage each stage from structural work right through to the final finishes with clear communication throughout. As part of our wider property renovations, we complete loft conversions regularly, giving homeowners a practical way to create extra living space without moving.

A smoother build from first plans to final handover

Our approach starts with understanding how you want the new space to function, because a good extension needs to feel like part of your home rather than an obvious add-on. As experienced extension builders, we guide the project from early planning through the build itself, helping you keep decisions organised and work on track.
 
Careful scheduling helps us reduce disruption. You'll also have flexibility in layout, size and finish, so the new space can suit anything from open-plan living to extra bedrooms upstairs. Nationcare Construction Limited regularly works for homeowners across Longfield, Wadhurst, Crawley and Redhill, delivering practical improvements with a solid, well-finished result.
