“We can’t recommend enough Lee Delaney and his team at Sienns Developments. They’re brilliant. They recently dismantled our old loft conversion and twisting staircase and completely rebuilt it, including an en-suite shower room, all within 5 weeks. And their price compares well to other building firms.”
“Working with Lee and his team has been a joy. Right from the very beginning we were able to quiz him on logistics and planning; Lee was able to recommend us a trusted team of architects, plumbers, plasterers, electricians, skips and scaffolders. He provided detailed quotes and stuck to his word always, extremely reliable.”
“Our experience working with Lee and his team was brilliant from start to finish. He was really helpful in the early stages of planning and suggested many ideas that have ended up making the space work even better than we had imagined. All the costings were presented in a clear and straightforward way and the initial timeframe was kept to and in the end even beaten! “
