Types of Extensions We Build

Create More Space With a High-Quality Home Extension

Single-Storey Extensions

Ideal for expanding kitchens, living rooms or dining areas. Single-storey extensions can dramatically improve your home’s layout and create brighter, open-plan spaces perfect for modern family living.

Double-Storey Extensions

A double-storey extension provides a major increase in space and long-term property value. Add bedrooms, bathrooms or office space upstairs while improving living areas below — a smart investment for growing households.

Side & Wraparound Extensions

Make the most of unused side space with a side extension, or combine it with a rear extension for a full wraparound solution. These designs work well in many Worthing properties, especially older homes and corner plots.

Rear Extensions & Kitchen Extensions

Rear extensions are a popular choice for creating large, open kitchen-diner layouts with plenty of natural light. We can incorporate roof lanterns, bi-fold doors, feature lighting and modern finishes to transform how you use the space.

Why Choose a Home Extension?

A professionally built extension can:

  • Create more usable living space

  • Increase your property’s value

  • Improve layout and flow

  • Add bedrooms, bathrooms or work-from-home areas

  • Make older homes feel brighter and more modern

  • Provide an alternative to moving

Many extensions fall under permitted development — and we’ll guide you through what’s needed from planning or building control.
