Expert House Extensions in Sussex & London

A house extension is one of the best investments you can make in your home. Whether you need a bigger kitchen, a new family room or extra bedrooms, extending your property gives you the space you need without the upheaval of moving.

At Into Build, we handle every aspect of your extension project — from initial design and planning through to construction and finishing. Our team works closely with you to create an extension that complements your existing home and meets your family's needs.

Types of House Extension

We build all types of residential extensions, tailored to your property and requirements.

Rear Extensions

The most popular choice for homeowners, rear extensions open up your ground floor living space, typically creating a larger kitchen-diner or open-plan family area that flows into the garden through bi-fold or sliding doors.

Side Extensions

Make use of unused side space to add a new room, utility area or expand your kitchen. Side extensions are often possible under permitted development, avoiding the need for full planning permission.

Wrap-Around Extensions

Combining rear and side extensions for maximum impact. A wrap-around extension can dramatically transform your ground floor, creating a spacious, light-filled living area that changes how you use your home.

Double-Storey Extensions

Get the most from your investment with a double-storey extension, adding living space on two levels. Extra bedrooms, bathrooms or a home office above a new kitchen — the possibilities are endless.
