So you have built a housing estate, sold the units, people have moved in and you have done the snagging. Well done! Job done, right?

Not at all! Those houses will be lived in for decades – possibly for centuries – and they will need maintenance. So will the infrastructure – drains, cables, pipes, wires, trees, plants. It will help future owners and managers immensely to have copies of all the plans and all the specifications in an accessible and future-proof form. Knowing where a pipe-run goes or who made the guttering can save so much time and expense so please try to hand over copies of everything and make sure that everyone associated with the estate can get at it.
