How Much Does a LOFT CONVERSION Cost in Barnes?

While there are many factors to consider before getting a loft conversion, you must not forget that in order to complete this project you must be able to allocate the appropriate budget for the design that you want to achieve. We will provide you with a detailed breakdown of the cost that your room may ask you after the initial inspection. Since a loft conversion requires an extensive construction process, expect that the cost may start at £35,000 and may go up to £85,000. Substantial factors that may affect the loft conversion expense are the type of loft conversion you’ll get, the materials that will be used in the construction, and the labor cost of the builders you will hire for the job.

Types of Loft Conversions in Barnes

1. Dormer Conversions SW13

A dormer conversion is the perfect solution for those looking to add more space and headroom to their loft. By extending the existing roof, a dormer provides extra floor space and vertical walls, making it a more viable option for lofts with limited space or headroom. While flat roof dormers offer the most internal space, they may not be the most visually appealing. On the other hand, gable fronted and hipped roof dormers look more attractive but come with a higher cost due to their complexity.

2. Mansard Conversions SW13

For those seeking a stylish and functional solution, a Mansard conversion is the way to go. This type of roof, named after the famous French architect Francois Mansart, features a nearly vertical lower slope and a horizontal top section. By choosing a Mansard conversion, you can add unique character and extra space to your property.

A Mansard loft conversion is a type of conversion that involves replacing the entire roof of your house to create maximum space within your loft. This is achieved by raising the party/gable walls on either side of your house to create the profile for the Mansard and then constructing the timber frame. While this conversion is common in older properties, particularly in cities like London, it is not often seen in the suburbs due to the high construction costs and need for planning permission. If you are considering a Mansard loft conversion, it is important to weigh the costs and benefits carefully.

On the other hand, Velux and roof light conversions (which are essentially the same, with Velux being a brand name) are a cost-effective and quick option that typically does not require planning permission. This type of conversion involves adding windows to the existing roof structure to bring in natural light and create additional space. If you are looking for a simple and affordable way to expand your living space, a Velux conversion may be the right choice for you.

Velux type loft conversions are a fantastic option for homeowners looking to add extra space and natural light to their property without breaking the bank. By fitting the windows flush with the roof line, there is no need for extensive alterations to the roof structure, which keeps costs down. This also means that planning permission is not usually required, although it is advisable to check with your local planning department before starting any works.

Velux conversions are particularly suited to lofts with a good amount of headroom or if there are planning constraints due to living in a conservation area. For lofts with limited headroom, a dormer or mansard conversion may be more appropriate.

One of the main benefits of Velux windows is how quickly and easily they can be installed, with minimal disruption or delays due to bad weather. Despite being installed at an angle, they still allow a surprising amount of natural light into the space.

Overall, if you're looking for an affordable and hassle-free way to add space and light to your home, a Velux type loft conversion is an excellent option to consider.

Get ready for the changing seasons with custom-fit window blinds for your Velux windows. No need to worry about ill-fitting blinds - our blinds are tailor-made to fit seamlessly into your window frame. Plus, opt for blinds with a thermal silver backing to effectively keep your space warm in the winter and cool in the summer. Don't wait any longer to upgrade your windows and enhance your home's energy efficiency.

A loft conversion can add significant value to a property, particularly in areas like Barnes. The addition of extra living space to your home is highly attractive to prospective buyers and will draw attention when selling. A well-designed loft conversion can also give you flexibility with regard to layout and design that can make the most of available space, making it both attractive and practical. The cost of the conversion will depend largely on the size of your loft and the complexity of the project, but it is typically an investment that pays off in terms of increased value.


The duration of a loft conversion can vary from one property to another, depending on the complexity of the project. Generally, it takes around 3 to 8 weeks. Most contractors will provide you with a timeline for the completion of your conversion as part of their quotation process. The process usually begins with a site survey, followed by the strip out of existing materials and the installation of new structural elements. Once this is completed, the plastering, carpentry, and wiring can begin. The duration of this stage depends on the size and complexity of the project.


The area of your loft conversion will depend on the size and shape of the space you have available. Generally, it should adhere to the guidelines set out in Building Regulations and the Party Wall Act. This would include ensuring that there is sufficient structural support and adequate headroom, as well as ventilation and lighting. You should also aim to keep the space as open as possible, to make the most of available light and space. This means that you may need to seek approval from neighbours before proceeding with a loft conversion project. Additionally, there are often other considerations such as the amount of light admitted or the height of the new ceiling that must be taken into account. Working with a professional loft conversion specialist can help make sure these details are taken care of and ensure your project meets all regulations.
