"Hi Charles,

In practice it doesn't matter that much, starting in the middle of winter can bring up some challenges, the shorter days can prolong a project. Apart from that you will good to start any time !

Thanks, Lucas - Hammond Property Solutions"

"I’ll find the best time to do building extensions from my personal point of view is in the months August September and October the working conditions are much better and temperatures are more workable with all materials but this is just a personal opinion"
