Landscaping- 23 Jan 2025
CNH did a great job on the bridge of our busy church in central Guildford. We had lots of positive feedback from our parishioners and they matched the colour of the resin bonding very well to the aesthetic of the building. The end result was that it looked like it had always been there, apart from the obvious newness of the surfacing.

Latest review:
Ionut and his team helped me with the garage conversion at my house. My initial plan was to utilise the garage as an office space. In the initial meeting, Ionut suggested utlising the space to build a guest bedroom with ensuite as well as an office. I was slightly concerned about this as I always thought that the space was too narrow (3.1 meters) to accommodate all this. However, I am glad that I trusted Ionut’s team as the layout and design was better than expected. The extension is now the best built and most spacious rooms in the house. I would highly recommend Ionut and his team.
