Deep foundations

The building work on our extension has started. The builders arrived this morning, starting over a month early, to begin our 2 storey extension which will give us an extra ensuite bedroom, another room down stairs and a down stairs loo and utility. The foundations had to be made an extra 800mm deep because of the large sycamore that borders our garden.
Hopefully the building work will be completed within 8 weeks, then the interior decoration can begin.
