Our range of house extensions

Side extensions

Many side extensions incorporate large windows, skylights, or glass doors to maximise natural light. This not only makes the interior spaces feel brighter and more inviting but also helps reduce the need for artificial lighting during the day, potentially lowering energy costs.


In some cases, homeowners may face restrictions on extending their home in certain directions due to planning regulations or property boundaries. A side extension can offer a viable solution, allowing for expansion without running into these constraints.

Rear extensions

Like side extensions, rear extensions provide additional square footage, allowing homeowners to expand their living areas. This extra space can be utilised for various purposes such as extending the kitchen, adding a dining area, creating a larger living room, or incorporating additional bedrooms.


Expanding the footprint of a home through a rear extension typically increases its market value. A well-designed and executed extension can significantly boost the resale value of the property, offering a favorable return on investment.


Kitchen extensions

Adding a kitchen extension can significantly increase the market value of a property. Kitchens are a key selling point for many homebuyers, and a modern, spacious kitchen can make a home more attractive to potential buyers, potentially leading to a higher resale value.


A kitchen extension provides homeowners with the opportunity to customise their space according to their specific preferences and lifestyle. From choosing materials and finishes to selecting appliances and fixtures. There are countless ways to personalise the kitchen to suit individual tastes.

Loft/attic extensions

One of the most significant benefits of an attic conversion is the addition of extra living space to the home. This can be particularly valuable for growing families, providing an additional bedroom, home office, playroom, or guest suite without the need for a costly extension or renovation.

Compared to building a new extension or undertaking major structural renovations, attic conversions typically have a shorter construction timeline. Since much of the existing structure is already in place, the conversion process can be completed more quickly, minimising disruption to the household.
