Why Bereco?

Bereco’s conservation approved Flush Casement timber windows from the Traditional Range with cottage bar design were the perfect choice. Slim frame sections maximise glazing areas whilst retaining the properties period aesthetics and complementing the Mills external façade. The noise of the river can be quite loud when in full flow and Restoration Man presenter, Architect George Clark was fascinated by the effective sound proofing properties the bespoke wooden windows provide.

The building was originally a working corn and water mill, and was used to make animal feed before its grinding days finally ended. The Hedley’s run holiday cottages and were looking to buy another property to transform into their new home. Margaret thought the mill was well out of their price range or capabilities but before she knew it Dave had made an appointment to view, and they subsequently found a way to buy it. Margaret had faith in her husband’s vision given she hadn’t seen the interior of the mill before they put the offer in.

“We are delighted with the windows – they look fantastic and everyone at Bereco has been so helpful. We were reassured by their experience and knowledge of Grade II planning restrictions”

Interesting Fact

One of the last major conservation areas to finish is the replacement of the mill wheel. The couple have had this remade with limited references to follow and it will be used as an energy efficient method of powering the property. When finished the wheel will surely be a striking main feature and the final touch to this unique restoration.

Special Requirements

The property is Grade II listed and there were 29 restrictions in total. Strict conservation requirements meant replacing the existing windows presented a huge challenge as the size of each opening could not be increased. Margaret was keen to ensure as much natural light entered the property as possible whilst framing the picturesque view of the river.

Beautifully constructed windows which do the job perfectly. Handled Covid disruption effectively. Installation went smoothly. All in all a job very well done. Would recommend without reservation.


Visited the showroom last year and impressed with the finish and quality. Just as delighted with the windows and back door that we ordered. They look fabulous.
