Rear L-shaped Mansard Loft Conversions London

A rear L-shaped Mansard is very similar to a rear mansard but simply extends out over the rear of the property to form another room. An L-shaped Mansard is particularly suited to a period property and a mid-terrace property. An L-shaped Mansard offers a solution to add the maximum amount of space to your home with a loft conversion permitted under planning regulations. An L-shaped Mansard can offer great features such as a rear terrace or Juliette balcony with French doors.

Why build an L-shaped Mansard?

If you love the area that you live in and don’t want the hassle or expense of moving but need more rooms and space for your growing family. Then an L-shaped Mansard loft conversion would be a perfect way to expand your space. L-shaped Mansard loft conversions offer a fantastic extension and use of space and are an excellent way to expand your home.

How much does an L-shaped Mansard cost?

Typically, an L-shaped Mansard will be slightly more expensive than a dormer loft conversion due specification and construction methods. When considering an L-shaped Mansard v’s a single rear Mansard, it is important to understand that the set-up costs, planning permission, permits etc will only apply once. If in the future you decide to amend from a single rear Mansard to an L-Shaped Mansard, there is a requirement to redesign, carry out new engineering detailing, obtain new party wall agreements and to submit for a new planning application. Effectively you will be paying twice for these elements and further for scaffold and other site set-up costs. Whereas doing the L-shaped Mansard loft conversion from the offset, whilst more expensive, it is not as much as paying twice for set up! Going beyond a single rear Mansard can bring huge benefits and easily make up for the relatively small price difference.

How long does an L-shaped Mansard take to complete?

This conversion type will typically take 8 – 10 weeks depending on the finishes and specifications. The design and planning permission phase will also need to be considered within your timings. Typically, initial design can take 4 weeks with planning permission taking a further 8 weeks to obtain. Give us a call for a free consultation and quotation.
