Large Side Infill Pitched Roof
Large Side Infill Pitched Roof House Extensions for London Homeowners
When planning a home extension, it’s essential to balance practical benefits with aesthetic appeal. A Large Side Infill Pitched Roof Extension is an excellent option for homeowners in London looking to transform unused space into something functional and beautiful. This article will guide you through the possibilities, costs, and considerations while offering insights into where these extensions are most popular and why.
Why Choose a Large Side Infill Pitched Roof Extension?
Adding a side infill extension is one of the smartest ways to maximize space, especially in urban areas like London, where every square meter counts. Here’s why a pitched roof version is particularly appealing:
- Increased Light and Space
A pitched roof allows for higher ceilings and the opportunity to add skylights, making your space feel open and bright. In my experience, adding three Velux windows turned what could have been a dark side-return into a bright, welcoming kitchen area. - Architectural Harmony
Unlike flat roofs, pitched designs align with the traditional aesthetics of London homes, especially Victorian and Edwardian terraces. - Practical Advantages
Pitched roofs provide excellent drainage, reducing the likelihood of leaks and extending the roof’s lifespan.
