What is a Single Story Pitched Roof Kitchen Extension?

A single-story pitched roof kitchen extension is an extension built to the back or side of your home, featuring a sloping roof. This design not only usually is a more affordable option with the roof finish matching the existing architecture of your home, but it also enhances the internal space with height and natural light when the ceilings are vaulted.
The pitched roof design allows for quick construction, saving on labor costs, while still offering an affordable yet stunning addition to your property. Furthermore, a wide range of roof tiles is typically available to match your existing house.

Benefits of a Pitched Roof Kitchen Extension
A pitched roof kitchen extension offers endless benefits, including increased natural light, quick construction and cheaper costs!. Moreover, working with an experienced architect ensures the design maximises these benefits and meets planning requirements.

Light & Ventilation
A pitched roof will enable you to add skylights & roof windows. Thereby, bringing in natural light and better airflow, turning a dark kitchen into a bright space.
Space and Value
This type of extension not only provides additional space, but IT can also increase your property’s value by up to 20%. A well-designed extension is a significant investment if it is designed and built correctly with the right permissions.
Architectural Appeal
The sloping ceiling from a pitched roof gives your kitchen a larger feel especially if the ceilings are vaulted. It adds character and helps modernise your home.

How to Vault a Pitched Roof Kitchen Extension
Vaulting the ceiling in a single-story pitched roof kitchen extension creates an open and airy feel. Therefore, here’s what you need to consider:
Insulation Specification
There's not a lot to vaulting your single story pitched roof kitchen extension. However, one of the key differences is the way you insulate the ceiling. You will need to achieve a ‘U’ value of 0.20W/m²K to the sloping ceiling. For example, you will want an PIR insulation board like Celotex at 100m thick between the rafters and 40mm thick under the rafters.

To give you an idea you will want an PIR insulation board like Celotex at 100m thick between the rafters and 40mm thick under the rafters.
Remember Vapour Barrier
The vapour control layer otherwise known as Vapour barrier or VCL is a very important aspect to the roof build up. You do not want moisture leaking into the walls or roof structure. If moisture can find a way into the building materials, it will continue to take this path and cause damage, rotting and grow mould. Which leads me onto my next point.

Key Considerations for Your Kitchen Extension
There are some essential factors to plan and optimise your kitchen extension project. Additionally, an architect can help ensure the design is practical, meets building regulations and works with your property’s layout.
Architectural Plan
Kirkwood provides detailed architectural designs tailored to your requirements, ensuring your extension exceeds expectations and meets yours and your families needs.
Planning Permission
Most single-story extensions fall under permitted development, which still require some form of permission. Fortunately, Kirkwood handles all planning permission requirements for projects that need approval. Learn more on the Planning Portal.
Kitchen Design
3D kitchen design service helps you visualise your extension, making it easier to plan the layout and style. For inspiration, explore design inspiration on Houzz.
Matching the Single Story Extension Materials to the House

Doors and Windows
You don't always have to match profiles exactly. In fact, a contrast between the windows and doors can look great. An architect will calculate how much glass or window space is required per square meter of roof and wall to meet building regulations and ensure adequate natural light.
Brick Matching
The builder will photograph your brickwork in natural light and consult online brick-matching services to achieve the perfect match.
Matching Roof Tiles
The builder will take clear photos of your existing tiles and source the closest match at a local builders merchants. Like Travis Perkins or Jewsons.
