London’s Leading Loft Conversion Specialist

A pre-conversion London loft provides a blank canvas for additional space, remodelling & creativity. This can be what you need to transform your living environment, adding comfort whilst also increasing the scale of your living space. It is not surprising that loft conversions are the most popular form of residential property conversion, and with the relatively liberal attitude towards planning permission associated with them, having a loft conversion is an excellent way of renovating your property. APT Lofts has a strong background in successful loft conversions of all types, and we have completed these across South West and West London. With our architecture, structural engineering and construction expertise, we are London’s loft conversion specialists of choice. With no third-party communications or sales involved, you can be assured that APT Lofts will design drafts, obtain planning permission and build your loft conversion to the highest standards, using materials of the finest quality.


The types of loft conversion design you can consider are Dormer, Mansard, Hip to Gable and Velux. The existing layout of the roof, and certain restrictions that apply, will determine the kind of loft conversion that the local authority will permit. APT Renovation can advise you on this issue when we make our free, no obligation visit. Many clients ask “can we still live in our house during works?” Our answer is simple: Yes! This is because 80% of the materials will be brought in via the roof.
