House Extension Types
Looking to create more space at home without the hassle of moving? A house extension can be the ideal solution – and at MJB Technical Services Ltd, we help homeowners across the UK plan, design, and deliver high-quality extensions that add value and transform the way you live.

Whether you’re after a bigger kitchen, a home office, or an extra bedroom, understanding the different types of house extensions is the first step. This blog covers the most popular extension styles, and how MJB Technical Services Ltd can support you every step of the way.
Single-Storey Rear Extension
A single-storey rear extension is one of the most popular house extension types. It extends the ground floor into the garden, creating valuable space for an open-plan kitchen, dining area, or family room.
- Great for kitchen/diner layouts
- Ideal for growing families
Wraparound Extension
A wraparound extension combines a side and rear extension, often forming an L-shape. It’s ideal for creating spacious, light-filled open-plan living areas.
- Maximises space and layout flexibility
- Perfect for kitchen/living/dining combos
Side Return Extension
A side return extension fills the often-unused strip of land at the side of a terraced or semi-detached house. It’s a cost-effective way to widen the rear of your home.
- Utilises wasted space
- Suitable for kitchen extensions
Double-Storey Extension
A double-storey extension adds space on both the ground and first floors, making it ideal for growing families who need extra bedrooms or bathrooms.
- Adds significant floor space
- Increases home value
Dormer Loft Conversion
A dormer loft conversion is a popular way to add a bedroom or home office without
extending the footprint of your house.
- Makes use of unused attic space
- Adds value and functionality
Orangery or Conservatory
Orangeries and conservatories are excellent options for homeowners wanting to add bright, airy spaces connected to the garden.
- Quick and cost-effective
- Floods the home with natural light
- Can be used year-round (especially orangeries)
