Guardhouse Way, Mill Hill NW7 — Kitchen extension by LCCL Construction

Guardhouse Way, Mill Hill NW7

Kitchen extension — 2000s semi-detached — Completed 2023

How design and build works

Anderson's note

On a house this new the ground floor is already open, so the job is really about the roof and the light: we put the skylights over the island before the kitchen layout was fixed, not after.

The client's view

“We did a 3 × 10 m single storey rear extension with LCCL recently. It was scheduled to take 12 weeks to complete but with Alex's experience and agile project management we finished in 10. Alex and LCCL are extremely knowledgeable and will work with you explaining what can, and cannot, be done and why. With Alex you know no corners will be cut: your house will be sturdy, warm, waterproof, and will look nice. Without doubt I would choose LCCL again for any future building project.”
