L Shaped Dormer Loft Conversion Barnet

L-shaped Dormer Conversion involves building two dormers that are connected to each other. One of the dormers is built on the main roof itself and the other to the rear of the roof which gives the distinctive L-shape dormer. Due to its unique shape, this type of loft conversion is only suited for Victorian and Edwardian properties where there is a back addition at the rear of the house.

L-Shaped Loft Conversion Barnet

L-shaped loft conversions are one of the best types of loft conversions, as they can create the largest internal space, with additional headroom too. This type of Loft conversion offers numerous configuration options, including the possibility of having more than one room. The L-shaped loft conversion involves an L-shaped dormer window. What are Dormers? These are the roof windows which extend vertically from the slope of a roof. Within the L-shaped loft conversions, the two dormers interwine into a corner.

In most cases, the larger end of the dormer is connected to the roof, while the other end is built into the roof of an existing rear extension. With the L-shaped loft Conversion, it is possible to get a headspace that is similar to the design of the first floor. A standard Loft conversion on a Victorian or Edwardian terraced property will usually bring about just a single room. In contrast, an L-shaped loft conversion can result in an additional second room.

How much does an L-Shaped Dormer Loft Conversion Cost?

An L-shaped loft conversion is not one of the most affordable options available. Our Prices start from around £46,000 for an L-shaped Loft Conversion in London. There is more technical structural work involved as the roof will be removed and rebuilt. You may need planning permission, depending on the limitations of permitted development rights, so factor in these costs and time constraints accordingly. Would you like to explore the possibilities for your loft space and obtain an approximate cost for the conversion? We offer a full design-to-build service and can quickly kick-start your project.

Does an L-Shaped Loft Conversion Require Planning Permission?

Most L-shaped Loft Conversions generally do not need planning permission as they fall under permitted development rights. We still recommend you check with your local authority's planning portal, as the rules vary from borough to borough. If your planned conversion is higher or wider than your existing roof, or if it exceeds 40 cubic meters (for terraced houses) or 50 cubic meters (for other properties), you will be required to submit a planning application. The permitted development rights allow you to extend your property without the need for planning permission as long as all building regulations and planning permission guidelines are followed. At Loft Conversion Barnet, we strongly recommend that lawfulness certificates be obtained from planning to ensure that you hold an official document stating that your development is legal.

Is my Property Suitable for an L-Shaped Loft Conversion?

An L-shaped Loft Conversion extends over the rear extension of your property, which already exists in many Victorian and Edwardian Houses across Barnet. It's ideal for Edwardian and Victorian terraced houses, where a rear addition is typically found, usually in the form of a kitchen on the ground floor and a bathroom above it. This means you have a good area to build on and achieve a much larger loft conversion. An L-shaped loft conversion adds significant amounts of space to your property, and both dormers will have good head height too.
