Google review
In 2025 we completed a house raise and extension with Manttan Constructions, led by highly experienced builder David Manttan and we couldn't be happier with the result. From start to finish, David's honesty, professionalism, and workmanship were exceptional. … It is clear that he takes enormous pride in the work he does, and the quality of the build is of the highest standard.

We recently asked David to remove the Arches in our home, increase the size of the openings, giving our aging home a truly great facelift. … They placed new supporting beams across the openings and were complete within the day. David and his team were extremely professional and knowledgeable. We could not recommend David more highly.
“Would recommend David. He has done work on our property before to a high standard.”
“Very approachable and knowledgeable, and will definitely use for any work on my house.”
“David was brilliant and did an amazing job! Very good, easy to deal with and a nice person. Would definitely recommend him to others.”
