Extensions- 12 Feb 2025
From the first communication with Stewart this has been the most easy and amazing process.. I honestly can't praise him and his whole team enough. The process has run so incredibly smoothly and quickly it's been amazing. It's difficult choosing a builder and we worried we would choose the wrong one, worried about how it would go..but we choose the best option. I would highly recommend Chez Construction to anyone looking for builders. It's taken around 3/4 weeks give or take from start to finish. Stewart was always on the end of the phone to respond to any questions wr had and dealt with the architect and council for us aswell. We are very very happy with our new extension.

We hired Iain to complete a rear single storey extension, to create an open plan kitchen and living space. Iain and his team were very efficient and open throughout the whole build. The work was completed in less than 3 months. Iain was very approachable and informative about the process and decisions to be made, and offered expert opinions throughout the project. We have young children and Iain and his team were very accommodating to our family life and ensuring the area was safe! We are really happy with the build overall and the quality of work produced. I would highly recommend IML Building and I would definately use for future projects.
