Back extension

Local Builder London have worked on many extension projects across London over the years and we know back extensions come in many various forms.

There are many factors to consider such as whether the building is single or double/two storey, the specific character of the building, the settlement area it resides within. Once the entire context is clear along with what your dream design is, Local Builder London can help you draw up designs to reflect the existing dwelling elements such as the scale of the building, materials which make up your current property, the specific shapes of your windows, contours and colours of your tiling, to the patterns of your brick work. Where possible we will look to source the same materials and use the same techniques whilst at the same time make sure the extension is a significant enhancement to your property.

This level of care and attention to detail is what you can expect from Local Builder London, whether it be a more simple and common extension you are looking for or a unique extension bespoke to your tastes.
