Anderson's note
Loft and extension together means one scaffold, one party wall process and one set of neighbours to talk to. We spoke to both neighbours before the notices went out and had consent on both sides within the fortnight.

The client's view
“Neighbours highly recommended LCCL Construction and we are extremely happy with the loft and wraparound house extension. The work is completed to a high standard and the team was a real joy to work with. This was our first building project and Alexander was there with us every step of the way. We have been living with our new spaces for 8 months now and there isn't a thing I would change — it is just perfect.”
