Why You Need a Loft ConversionLoft Conversions in London

If you are running out of liveable space in your home, and don’t wish to move to a larger property, you will need to find ways to gain space in your current home. If you have the outside space required, then a house extension is often the best way to achieve this. However, if you haven’t got the needed outside space to spare, you might be wondering what your next step is.  

This is where we come in at Firtree Building Services, as these situations are ideal for the conversion of your loft space. Lofts are often unused, and they are a wealth of untapped potential, so converting the loft can provide you with the much needed extra living space.  

Benefits of Loft Conversions Over House Extensions

There are many reasons to invest in a loft conversion over a house extension, with the primary benefit being you often don’t require planning permission for a loft conversion. Converting the loft generally comes under permitted building work, so you won’t have to wait around for planning permission to come through to begin the project. This means you can get the project completed much quicker than an extension, which can save you money too.  

Additionally, you won’t need to sacrifice any outside space in order to gain extra space inside. Since most lofts are unused, you won’t be sacrificing any space at all, simply gaining it.  

Duration of a Loft Conversion Project

While each loft conversion project will take a different amount of time, depending on the requirements and how much work needs to be done, the general time frame is around 6-7 weeks. This is for the entire project, from the initial design right through to the build phase and final sign off – it takes much less time than an extension as you won’t need to wait for planning permission.  

Loft Conversion Cost in London 

As with the time frame, the cost of your loft conversion in London will depend entirely on the project itself. Generally, you can expect a loft conversion to cost around £30,000 to £40,000, but this will vary depending on your individual requirements, what type of conversion you choose, and any extra work that needs to be carried out.  

We will always provide you with a bespoke quote before we carry out any work, and a loft conversion can increase the value of your property, so it is an investment too.

    Internal Loft Conversions  

    These are the simplest and most affordable choice as it requires little work to be carried out. The existing loft space will require minimal alterations and small additions such as roof windows, insulation, and stronger flooring.  

    Dormer Loft Conversions  

    Dormer loft conversions involve adding dormer windows to the loft space, which increases the height of the room. They are generally added to the back of the property but can be added to the front and side with the relevant planning permission.   

    There are various styles of dormer loft conversion, including single and full width, l-shaped, and hip to gable.  

    Single Dormer  

    A single dormer conversion is when a single box shaped structure is added onto the roof, creating more headspace and a window for the loft.  

    Full Width Dormer 

    A full width dormer is similar to a single dormer, but it is larger in width to create more space within the loft.  

    L-Shaped Dormer

    An l-shaped dormer is an addition to the roof and loft space that creates an l shape. Two dormers are attached, one to the main roof and one to the rear of the roof.  

    Hip to Gable  

    A hip to gable conversion is generally found on properties with an existing hipped roof, where the hip is extended up vertically from the ridgeline. This creates a gable, and a rear dormer is formed on the rear of the property.  

    Roof Off Loft Conversions  

    A roof off loft conversion requires the most work, as the existing roof will need to be removed and replaced with a brand new structure. This creates much more headspace in the loft.
