Types of House Extensions

We offer a range of home extensions to suit different homes, budgets and layouts. The right option will depend on your property, your goals and how you want to use the extra space.

  • Single Storey Extension - A single storey extension is ideal for creating an open plan kitchen, dining room or larger family living area. This is one of the most popular ways to improve the layout of your home and make better use of the ground floor.
  • Double Storey Extension - Double storey extensions are a great option if you need substantial extra space. They can add valuable new rooms on both floors, making them ideal for growing families or homeowners looking to increase living space and property value.
  • Wrap Around Extension - A wrap around house extension combines side and rear extension space to create a much larger footprint. This style can transform the flow of your home and works particularly well for larger kitchens, dining spaces and open-plan layouts.
  • Second Storey Additions - A second storey extension can be a practical way to build upwards rather than outwards. This approach may suit properties where outdoor space is limited but more internal room is needed.

Do Home Extensions Need Planning Permission?

Some home extensions are classed as permitted development, which means they may not require planning permission. However, this depends on the size, design and location of the extension, as well as the type of property.

For example, factors such as whether the work is single storey or two storey, how far it extends from the original house and the materials used can all affect whether planning permission is required. If your home is in a conservation area or has already been altered, further rules may apply.

We can guide you through the planning side of your extension project and help you understand whether your proposed house extension falls under permitted development or whether you will require planning permission.

Benefits of a House Extension

  1. Create More Living Space - A house extension is one of the most effective ways to add living space without leaving the home you already love. Whether you need a larger kitchen, a separate dining room, another bedroom or a more flexible family area, an extension can make your property work better for you.
  2. Add Value to Your Property - Well built home extensions can add significant value to your home. Extra floor area, improved layouts and better functionality can all make your property more attractive to future buyers.
  3. Avoid the Cost of Moving - Moving house can be expensive and disruptive. Extending your current property can often be a more cost effective way to get the extra space you need while staying in an area you already know and enjoy.
  4. Support Modern Living - Many older homes were not designed for the way people live now. A well planned extension can create bright, open spaces that support family life, working from home and everyday comfort.
