Good experience with Next Gen builder
Next Gen Builder were brilliant from start to finish. Quick turnaround, fair pricing, and the quality is exactly what we hoped for. The underfloor heating is a nice touch — warms up evenly and makes the room feel cosy. Would recommend.Verified reviewerJob location: SM610 Extensions / Conversions

Side extension
Next Gen did our side extension and I’m really happy with how it turned out. Took a bit longer than I thought but to be fair the weather was awful. The end result is worth it — proper solid job.Verified reviewerJob location: CR89.67 Builder
