Rear Extensions are one of the most popular ways to improve your home and add value to your property. They can massively transform your interior by creating large open-plan spaces that open up your home. With large folding doors, a rear extension can also create a flow from your new open-plan space to your garden.

But before you get the sledgehammer out and start knocking down walls, there’s some work to be done. That’s where we come in. We’ll help you to design your perfect kitchen / diner, gym, workshop, office or whatever room you want an extension for. We’ll also provide the relevant structural plans to ensure that the building work is carried out accurately and safely.

Planning Consent

But beyond the architectural design, there’s plenty more that we can help you with. We’ll help to take away a lot of the headaches that come with building an extension. Whether or not you need planning permission is one of the key questions that customers ask us. It might be that you do not need planning permission if you fall within the permitted development rights.

We can advise on whether or not you need planning consent and help you with the whole process. Even if your rear extension complies with permitted development, it is sometimes advisable to apply for a Lawful Development Certificate. Again, we can help you this and with the whole planning permission process.

Building Regulations for House Extensions

Building Regulations are UK standards for the construction of new buildings, extensions or renovations to ensure safety and quality. They take into account the structural integrity of the building work and, amongst other things, fire safety, ventilation, glazing and drainage etc. Part of the service that we provide is ensuring that your building work conforms to building regulations. Learn more about Building Regulations.

Natural Light

An advantage of building a new rear extension is the opportunity to add rooflights or skylights. These essentially are windows in the roof of your new extension. So whether you opt for a flat roof or a pitched roof, we can incorporate rooflights into your design. This has the huge benefit of allowing a lot more natural light to flood into your new living space.

Rear extensions are also often built with large folding doors. Not only to they look stunning from the outside, but they allow natural light to flood into your new extension. And from the inside they perfectly frame your garden, allowing you to look out onto it every day.
