Single Storey House Extension
One of the most popular types of house extension is a single-storey, often seen as a kitchen extension. Single storey extensions are often built on the side or rear of the house. This utilises the unused garden space and gains valuable kitchen space. French doors and bifold doors are often used to invite natural light in.
Two Storey House Extension
Double storey extensions cost more than a single storey but can be budget efficient. With the average cost per square metre being lower on the double storey. This is because foundation and roofing costs are similar for both types. They can gain the family home an extra bedroom and a larger hosting area downstairs. Increasing the value of the property.
Rear House Extension
With a high likelihood of planning permission approval and minimal disruption to neighbours. Rear extensions are a prevalent type of home extension in the UK. By extending your property out into your garden space, You can create a large open plan living area and kitchen.
Side House Extension
Like the rear extension, a side home extension can be single or double storey. But if you don't have much garden space and have unused space on either side of your home. A side extension can be a great option to extend your family home. A prevalent use of this extension is to add an extra bedroom or increase kitchen and bathroom space.
Wrap Around House Extension
A wrap around extension is an L shape extension that is at the back of the property. It is a combination of the popular side and rear extension. And can be either single or double storey, depending on the budget. By adding extra property space on the rear and side, the possibilities are endless when it comes to design.
Side Return House Extension
This type of extension is similar to the rear as it's built onto the back of the house. But the aim of this extension is to make use of the wasted space called the " Side return ". This is the small alleyway that runs along the side of your house. With this extension, you can gain space without losing any of the garden.
Over Structure House Extension
This type of extension uses the existing property footprint to build upon. The most common type is building a small extension above the garage. Where you can create an extra bedroom for the house or a comfortable office space. This allows extra living room without taking any of the existing ground level space away.
