"This is our second time using JN Construction, this time for a much larger project - a double storey side extension + single storey (2 bedrooms, 2 bathrooms, Kitchen & reception) This was a challenging build to say the least but James and his team took charge and dealt with the issues we faced. At every stage during the build we were consulted & advised and we felt "part of the team" not just the customer. Given our issues (disabled son) we had to work together to minimise any distress, they were so understanding (amazing) in fact. WE now have an AMAZING house, so thank you James & Team"

What customers say
3 highlightsCustomer voice from the public record
"James has been truly exceptional throughout the whole process. From initial meeting right up to signing off with building control. We absolutely love the final outcome in having a beautiful downstairs bedroom/ utility room and cloakroom. James quote was very competitive and nicely presented and professional. The quality of the work is excellent and his project management with subcontractors was smooth and seamless. The job was finished as scheduled with no interruptions or issues. No hidden costs or stress and would definitely use him again for further works and highly recommend."
"I spoke to several companies, and James was by far the most professional and capable person I spoke to. I am delighted with the outcome of my loft extension, it’s made a massive difference to our family home and house value. James was very organised, the finish was really good, and left our home tidy and clean. We would highly recommend him to anyone wanting to have a high quality loft conversion, and be the envy of the street."
