“The Newstock team carried out a massive refurbishment on my bungalow including the demolition, only leaving 2 walls standing.

Refurbishment including foundation drainage and building the full shell to watertight this was all carried out in great time consider the bad rain we have had the last few months.

Thanks Newstock Developments.”
