FAQs When Building a Single Storey Extension
Are you thinking of adding more space and value to your home with a single storey extension? If so, you might have some questions about the process, the costs, the design and the regulations involved. In this blog post, we’ll answer some of the most common FAQs that homeowners in the UK ask when planning to build a single storey extension.

What is a Single Storey Extension?
A single storey extension is an addition to your home that extends from the ground floor level. It can be attached to the rear, side or front of your house, depending on the layout and orientation of your property. A single storey extension can provide extra living space, such as a kitchen, dining room, lounge, bedroom, bathroom or home office.
Do I Need Planning Permission for a Single Storey Extension?
Not necessarily. Many single storey extensions can be built under permitted development rights, which allow you to extend your home without applying for planning permission, as long as you follow certain rules and limits. For example, your extension must not:
– Extend beyond the rear wall of the original house by more than 4 metres if it’s detached, or 3 metres if it’s attached
– Extend beyond the side wall of the original house by more than half its width
– Be higher than 4 metres or higher than the existing roof
– Cover more than half of the land around the original house
– Be within 2 metres of a boundary if it’s over 3 metres high
– Have a veranda, balcony or raised platform
– Use materials that are different from the existing house
However, there are some exceptions and variations depending on where you live and what type of property you have. For example, if you live in a conservation area, a national park, an area of outstanding natural beauty or a World Heritage Site, you may have more restrictions on what you can build. Also, if your house is listed or has been extended before, you may need planning permission for any further extensions.
How Long Does It Take To Complete an Extension?
The duration of your single storey extension project will depend on the complexity and scale of your design, as well as our availability. However, as a general guide, you can expect to complete a single storey project in approx 12 to 16 weeks from start to finish.
Here is a typical timeline for a single storey extension project:
– Week 1: Site preparation and groundworks
– Week 2-4: Foundations and drainage
– Week 5-6: Brickwork and blockwork
– Week 7-8: Roof structure and covering
– Week 9-10: Windows and doors installation
– Week 11-12: First fix plumbing and electrics
– Week 13-14: Plastering and drylining
– Week 15-16: Second fix plumbing and electrics, flooring, decorating and finishing touches
Of course, this timeline may vary depending on the weather conditions, unforeseen issues and any changes or delays that may occur during your project.
What Are Some Design Ideas?
There are many ways to design a single storey extension that suits your needs, preferences and budget. Here are some popular design ideas to inspire you:
– A rear kitchen-diner extension that opens up to the garden with bi-fold or sliding doors
– A side return extension that fills in the wasted space next to your house and creates a larger kitchen or living area
– A wrap-around extension that combines a rear and side extension and maximises your ground floor space
– A front porch extension that adds character and curb appeal to your house and provides extra storage space
– A sunroom or conservatory extension that lets in natural light and creates a cosy and relaxing space
