Extensions- 8 Oct 2018
Alton and his team at Bluelime have been incredibly helpful and enthusiastic throughout our design and planning process. From the start, Alton took his time to understand our needs and propose several cost-effective ways to improve my home and create more space for my growing family. The design process was completed efficiently and submitted for planning permission, which was granted without a problem. Since then, his team have continued to be helpful and communicative despite my need to delay to the building works due to unfortunate complications with my freeholder.
