Loft Conversion Near You in South West London UK
25, Jun, 2025
If you’ve been searching online for a loft conversion near me in South West London, chances are you’re ready to transform your unused attic into something more valuable, like a bedroom, office, or even a stylish en-suite. In places like Wimbledon, Clapham, Balham, and Putney, loft conversions are one of the smartest ways to add space without moving home.
This guide will walk you through everything you need to know if you're planning a loft conversion in South West London, from design tips to costs and local regulations.
Why Consider a Loft Conversion in South West London?
Property prices in South West London are high, and moving to a larger house isn’t always possible. Many people go for a loft conversion for their terraced home or a semi-detached home, and it's also a very common cost-saving method to:
Have a new bedroom or bathroom area
Make your property more valuable
Maximise the space that is not used and stay without moving
If you have a pitched roof with a height of approximately 2.2m, it can be converted.
Types of Loft Conversions
If you live in the South West London area and want a loft conversion, there are many types to choose from. The best way is to hire a professional, such as Denham Crescent, who will visit your property and assess the existing roof, including its type, shape, and the budget required. Let’s see some common types of loft conversions:
1. Dormer Loft Conversion
One of the most popular choices in South West London. A dormer adds a box-shaped structure to the roof, creating more headroom and usable floor space, perfect for larger bedrooms or en-suite bathrooms.
2. Velux (Rooflight) Loft Conversion
Ideal if your loft already has good height. It’s the most affordable option and involves fitting Velux windows into the existing slope, without changing the roof shape.
3. Hip to Gable Conversion
Best for end-of-terrace or semi-detached homes. It straightens the sloping side of the roof to create more space inside, often paired with a rear dormer.
4. Mansard Loft Conversion
Common in conservation areas like parts of Battersea and Wandsworth. This type changes the slope of the roof significantly to create a flat rear wall and roof, offering the most room overall.
Do You Need Planning Permission?
The loft conversion in South West London comes under the permitted category, so you don’t need permission. However, in some cases, you will require permission for the build, especially in the case of dormer and Velux-style loft conversions. Some exceptions are:
If your home is in a conservation area
If you plan to raise the roof or build on the front side
If your property is a flat or maisonette
Always check with your local council (like Merton, Wandsworth, or Lambeth) or work with a loft conversion company that handles permissions and building regulations for you.
How Much Does a Loft Conversion Cost in South West London?
The cost of a loft conversion near me in South West London depends on:
The type of conversion
The size of your space
Whether you’re adding plumbing (e.g. for a bathroom)
The materials and finishes you choose
On average:
Velux loft conversion: from £25,000+
Dormer loft conversion: from £35,000–£50,000
Hip to gable or mansard: £50,000 and up
It’s best to get a professional survey and quote based on your exact needs.
