Design and build inclusive: architecture, structural engineering, planning, party wall, construction, project management and LABC sign-off under one contract.
Anderson's note
Victorian terraces give you the depth but not the width, so the skylights do the work: we ran them the length of the kitchen so the middle of the plan is as bright as the garden end.

The client's view
“Professional and trustworthy design and build construction company. Alexander has been working on our home and has done an amazing job. I did not know much about architecture or construction of home extensions but Alexander made sure I was always informed. He brought a lot of ideas to the design and interior design, and construction went smoothly from kitchen to plumbing and electrics. I had the best experience from LCCL Construction and would highly recommend them.”
