Building Alterations
- Internal Alterations: We specialise in transforming your existing spaces to better suit your needs. Whether it's reconfiguring room layouts, removing or adding walls, or simply updating interiors, our team ensures a seamless process with minimal disruption at all times.
- Structural Alterations: We have the experience to carry out structural alterations such as removing load-bearing walls and installing beams to create open-plan living spaces. As you would expect, all our structural work complies with building regulations and is carried out safely.
- Accessibility Improvements: We understand that circumstances or a change in living arrangements can mean you need to assess the accessibility of your home, and that this can seem daunting. We can discuss your needs with you, including the installation of ramps, wider doorways, and adapted bathrooms.

Home Extensions
- Single-Storey Extensions: Looking to extend your living space with a single-storey extension? This can be used to create a larger kitchen, a new living room, or an additional bedroom. Our designs ensure the new space integrates seamlessly with your home.
- Double-Storey Extensions: If you need more space, our double-storey extensions can provide additional rooms both upstairs and downstairs. This option is perfect for growing families or those needing more functional space.
- Side and Rear Extensions: We can build side and rear extensions to maximise the available space on your property. These extensions are designed to complement your home’s existing architecture while providing the extra room you need.
- Bespoke Design: Every extension project is tailored to meet your specific needs and preferences. We work closely with you to ensure the design enhances both the functionality and aesthetics of your home.

Conversions
- Loft Conversions: Transform your unused loft space into a functional room—an extra bedroom, office, or playroom. We include everything from planning and design to construction and the all-important finishing touches.
- Garage Conversions: Convert your garage into a usable living space, whether it’s an additional bedroom, a home gym, or a studio. Our team handles all stages of the conversion, ensuring a smooth transition from start to finish.
