Pitched roof single storey extension: is it right for your home?

A single storey extension is an excellent way to bring to life your desire for more home space without moving house.

As much as you would love to get right to the decoration and aesthetics part, it’s vital to consider the structural aspects first. Depending on what you have in mind, you could choose a flat or a pitched roof single storey extension.

This blog post focuses on the pitched roof single storey extension, but you can check our article on flat roof single storey extension for info on the former.

Why install a single storey pitched roof extension?

  • A pitched roof design generally blends in better with the aesthetics and style of more traditional houses. As a result, planning departments tend to favour pitched roof extensions over flat roof extensions.
  • A pitched roof is more energy efficient as it allows for more insulation than a flat roof.
  • Pitched roofs have a longer life span thanks to the materials they are made of and their general design (their sloped shape prevents leakage due to water accumulation).
  • Pitched roofs typically have higher ceilings. These higher ceilings offer more height and give the room an illusion of being bigger and more spacious. The higher ceilings also can accommodate architectural features such as beams and sloping ceilings.

Types of pitched roof extensions

There are five types of pitched roof extensions. Each of these pitched roof single storey extensions differ by several factors, like their building cost and how the finished roof looks with your home. While some roofs offer more space, others are more durable and resilient against extreme weather. The types of pitched roof extensions are:

Gable roofs

Gable roofs are the classic inverted V roof design with a strong and timeless appeal. While they are well known for their ability to resist the elements, they do not do too well in places like the Highlands because they are susceptible to very high winds.

Gambrel roofs

Gambrel roofs, also called barn roofs, are very popular in the UK for their rural aesthetic look. These types of roofs are very sturdy, visually appealing and can support a wide range of accessories and additional features.

Hipped roofs

Hipped roofs are sloped on all four sides instead of the two-sided slopes other pitched roofs are characterised by. Although trickier to construct, these roofs are known for their classic visual appeal and ability to withstand poor weather conditions.

Single slope roofs

Single sloped roofs are perhaps the least expensive of all pitched roofs. They’re extremely easy to construct and do very well in extreme weather and temperatures.

Mansard roofs

A mansard roof is a cross between a hipped roof and a traditional gable roof. It combines the appeal and functionality of both to birth a sturdy, elegant architectural design. However, this roof is somewhat tricky to construct and so may require expert assistance.

How much do pitched roof extensions cost?

The cost of a pitched roof extension depends on several factors, like the size of the extension, the home’s location (inside London is usually more expensive), the materials that will be used, contractor, and design complexity.

Here are some guide prices for constructing common pitched roof extensions.

Ground floor rear extension (30 sqm)

£37,000 - £80,000

Ground floor side return extension (30 sqm)

£43,000 - £80,000

Ground floor wraparound extension (45 sqm)

£65,000 - £120,000

Please note: these values are rough estimates and do not include VAT at 20%. They also do not include key fit-out items, such as kitchens, glazing, landscaping and bathrooms. London properties will be at the higher end of these estimates.

Regulations and requirements

You’ll only need planning permission for your pitched roof extension if it doesn’t follow the requirements of your permitted developments rights.

Permitted development rights allow you to make certain changes to your house without submitting a full planning application, but there are exceptions to this rule. It doesn't apply to flats, maisonettes, listed buildings or homes located in conservation areas.

You’ll also need to make sure that your finished build complies with building regulations, and that you’ve had a structural engineer on board to provide the proper calculations. What’s more, if your project affects a shared wall or boundary with a neighbour, you’ll need to get party wall permissions in place before construction begins.
