Carpentry- 19 Sep 2015
Not only was Ian's quote to do the loft conversion very reasonable, he was very reliable, tidy & very helpful when we had a difficult situation. The work was done in a quick time, when he said he was going to be on site he was, at no time did he let me down. The standard of work was excellent, I would recommend Ian & wouldn't hesitate to use him in the future.

Extensions- 23 Feb 2020
We hired Arra brickwork to complete what looked like a straight forward side extension, this soon became very complex due to the angle of the build and the roofing. Whilst we had our own expectations, Aushra was very helpful in presenting more ideas and suggestions in line with what we wanted. She even went as far as building sample model to show us what the build would look like. We found Arra brickwork - Aushra and Authur to be genuinely nice people, they are very polite and very tidy workers and put in so much effort to complete the build, even when we didnt expect them they were there working hard. We had full visibility of spend as Aushra was prompt at letting us know how much materials would cost including the initial quote for the build which was reasonably compared to what we had previously been quoted. We could not ask for a more trustworthy team of builders who cares about what they do and I will not hesitate to hire Arra Brickwork again for any more projects.

What experience do you have with similar extensions in New Cross?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the New Cross extension builder’s ability to deliver a result that meets your expectations.
