Renovation of Rear Extension - Kitchen and Back Room (Part 1)

Verified Review

We have been really impressed with the work carried out by Carl and his team so far. They have removed the wall separating our kitchen/back room, fitted steel beams, raised floor, door and window (as room was across two levels) plumbing work and new Velux windows. The entire team have been friendly, hard working and tidy. The level of workmanship is clearly to a very high standard and they have communicated with us throughout to ensure we are happy with everything. We are extremely satisfied with the work carried out to this point and looking forward to the next phase of development.

Construction of a large 2 storey Annexe, with link extension, including feature vaulted roof.

Verified Review

Project - 1930’s Arts and Crafts Detached House. We have been extremely satisfied with the first phase of work undertaken - Hammers Construction are an exceptional team that work together seamlessly and professionally. Both the brickwork and roofing carpentry was exceptional. They were totally reliable, punctual, driven and kept us up to speed regularly with progress reports. The team have absolutely delivered this complex and challenging project, on time and on budget. We would have no reservation in recommending.

Ground floor rear extension and complete refurbishment of entire house

Verified Review

End of project review. Our house and patio/garden is now complete and we couldn’t be happier with everything. Complete transformation! All work completed to a very high standard with only a minor delay due to weather. As always the team were great to deal with and were able to help solve any problems quickly as they arose. Carl has a great eye for detail to pick up on any finishes and ensure that the finishing is very high quality. As stated previously work was as per quote with any additional costs (generally due to our requests) made clear before work was done. Thank you so much Hammers
