Lumen provides an environmentally friendly option for an Area of Outstanding Natural Beauty

Situated in an Area of Outstanding Natural Beauty (ANOB), the Hince family home is located in the heart of the stunning East Sussex countryside. In 2016 the couple decided to expand their property to the rear with a single story extension, which would open up the magnificent views of the surrounding countryside.

After a 4-month renovation project, involving Architect Carlos Elsesser, from AAC Studio and the builder W.Smithers & Sons, the flat roof extension has created a bright new living space, which incorporates a new lounge, dining and kitchen area.

The crowning glory of the new living space is a large bespoke Planus Accoya™ rooflight (designed for use on a flat or low pitch roof) and hand crafted by Lumen to the exact specifications of the client. The 2864mm wide by 1469mm high rooflight is constructed from Accoya timber and benefits from excellent stability, durability, UV resistance and a very long life.

Due to the large size of the rooflight, the Accoya™ provided a lighter framing structure which allowed the introduction of a high specification triple glazed, self cleaning, Pilkington unit with a 6mm toughened Pilkington Activ Sunshade neutral outer.

The architect was also keen to find a product without a glazing bar, with a single pane of glass and a minimal frame size to maximize the light entering the room.

“The rooflight was specified by Carlos, who initially provided us the option between the Lumen product and one other less sustainable alternative. Lumen was able to build us a rooflight to the exact size and specification that we wanted, while Carlos was impressed by the thermal qualities of Lumen’s product. Not only did we and Carelos decide that the Accoya rooflight provided a better quality option, but it was also reasonably priced in relation to the alternative.”

“At first we were worried about the levels of light entering the property, as the original windows were quite small and the old lounge area was fairly dark. However, we need not have worried as the windows and glazed door to the rear of the extension provide plenty of light, while the large rooflight now floods the room with light from above. Even on a dark day the space feels light and airy and has become the new focal point in our home - it’s now where we spend most of our time."

Lumen also supplied an insulated kerb upstand, which made life easier for the builder and offered an exact fit of the bespoke rooflight design. As part of Lumen’s bespoke design Trevor and Sarah were also able to specify differing internal and external colours rather than just a single option. They opted for an RAL.7024 Graphite Grey external, with an RAL.9010 white finish on the inside. Lumen also supplied a custom made, remotely operated electric blind, to match the colour scheme chosen.

The Lumen Planus Accoya™ is manufactured to the highest standards in the UK and is hand finished to the exacting requirements of each customer. Lumen also prides itself on its customer service, which was something that the Hince family were particularly impressed with.

“The Lumen team were on hand throughout and were a pleasure to deal with. They took care of everything from the initial drawings and design suggestions, through to the ongoing liaison with the architect and builders. Lumen absolutely met the brief and we are delighted with the end product."
