- Single Storey Extension - a fantastic way to add more space to your kitchen, which enables you to include a dining space while only changing the first floor of your house; when choosing this particular extension, make sure its roof complements the exterior of your house.
- Rear Kitchen Extension - it extends from the back of the house and usually very popular where there is no side return option; it has three different roof options (a mono-pitched roof, a centre-pitched roof, and a flat roof); it is, however, likely to reduce the green space around your house.
- Side Return Extension - an extension option that suits most houses that were built in the Victorian or Edwardian era or are inspired by these styles; it is usually fitted in a gap at the side of the house typical for such designs.
- Conservatory Extension - the perfect choice for homeowners that feel like there isn't enough natural light inside their home; it has glass features that will create a breathtaking view, especially if you live surrounded by nature; one of the cheapest extension options available.
- Wrap-Around Extension - it is one of the largest extensions on the list, so it requires a bigger budget, but it will also leave you with the most additional space; it offers two options for the roof, a pitched or a flat roof.

In the UK, a single-storey or double-storey extension might be built under current permitted development rights for extensions, if:
- The single-storey extension is up to 6 metres from the original rear wall of an attached house and up to 4 metres high; however, if the extension is planned within two metres of your property boundary, it can be only 3 metres high.
- The double-storey extension can't be taller than the highest point on the roof of your house, and can't extend beyond the rear wall by more than 3 metres; it also has to be at least 7 metres away from the boundary of your property.

However, if you wish to invest in an extension that doesn't fit in with the requirements mentioned above, you will need to apply for planning permission, which will cost around £200, the final price will be determined by your proposition and the part of the country you find yourself in.
