Explore serviceA rear extension in Bishop's Stortford — from bare plaster and screed to a finished open-plan kitchen with a bespoke island, herringbone flooring and flooded with light from the new roof lantern.
Nevill Construction Ltd grew out of carpentry, and it shows in the details other builders miss: scribed skirting, hand-built cabinetry, staircases and balustrades that feel solid for decades. When your extension needs a bespoke media wall, your loft needs fitted wardrobes in the eaves — or you want a golf simulator room in the spare room — we build the space for it ourselves rather than fitting something off the shelf.

“A dream home come true — thanks to Dan and the team! They started our extension in March and within six to eight weeks completely transformed our home. We finally have the kitchen we always dreamed of, complete with a beautiful island. They also did all the landscaping, installed stunning composite decking and prepared the base for artificial grass. The attention to detail has been second to none.”
“We used Nevill Construction for a loft conversion and rear extension. From the first meeting, Dan stood out — professional, genuine and easy to trust. His team was reliable, tidy and responsive, the snagging list was handled quickly, and there was a clear payment plan with no pressure. We've already recommended him to friends.”
“Dan and his team completed a 3-metre extension on our home. They were reliable, polite and professional, and showed great respect for our home during the busy school-run mornings. Dan made frequent visits, answered every question and was open to changes along the way. We wouldn't hesitate to recommend them.”
“Excellent service and great communication. We had some in-built wardrobes made and nothing was too much bother. The team listened to what I wanted and completed the job professionally.”
“Quality work from all of Dan's workers! This is the second project we've had Dan do — and the third one is in the works.”
“Dan and his team did an incredible job on my loft conversion. They were always respectful of neighbours and how they worked within my house, and communicated well on timelines. I'm really happy with the work and will be looking to have them do an extension in future.”
