Is a double-storey extension right for your home?
Adds space on both the ground and first floor, commonly an extra bedroom or bathroom above a rear or side extension.
- An additional bedroom or bathroom
- Adding value across two floors at once
- Households that need more space upstairs, not just down
Worth considering: Typically the largest undertaking of the extension types, with the longest programme.

We don't rush the build. We remove the delays.
A property development background means the trades, materials and scheduling for your double-storey extension can be coordinated properly, so the project keeps moving without the build quality suffering.

Other extension types worth a look
Rear Extension
Extends the back of the house into the garden, most often to open up the kitchen and create a kitchen-diner.

Side Extension
Fills an existing side return or side gap, often used to widen a narrow kitchen or add a utility and downstairs WC.

Extension FAQs
Do I need planning permission for an extension?
Many extensions can be built under Permitted Development rights, but this depends on your property, its planning history and local restrictions. We'll help you understand what applies to your home before design work begins.
What type of extension can I build?
The right configuration, rear, side, wraparound or double-storey, depends on your garden, existing layout and what you're trying to achieve. Our extension explorer is a starting point; a site visit confirms what's realistic.
How long does an extension take?
Timelines vary with scope, so we don't quote a fixed figure until a project has been properly planned. What we can say is that most delay in building projects comes from poor preparation and uncoordinated trades, which is exactly what our process is designed to remove.
Will I need to move out during the build?
Most extension projects allow you to stay in your home, though there will be periods of disruption, particularly around structural work. We'll talk through what to expect for your specific project.
