What is Mansard Loft Conversion London

Windows, small dormers, will then be built into the new roof and it can sometimes be possible to add a Juliet balcony. This kind of conversion can also potentially support several rooms such as a couple of extra bedrooms and a bathroom. This type of conversion is suitable for most types of property to include mid terraces and the finish can be tailored to suit your property.
