Knocked Through & Watertight Within a Week!

Mr & Mrs Mayfield live in a beautiful, detached house in Leicester. They wanted to extend to create an open plan kitchen/dining area and bring light into their home from the back of the house. The extension had to fit in with the look and style of the existing property from the outside and provide a comfortable, light room.

The couple were recommended to their local hup! builder, Harveys Windows & Conservatories, and began to discuss their ideas, resulting in a stunning hup! design featuring a Flat Roof and a central lantern. With the combination of glazing and solid areas, the space was designed to be warm and comfortable all year round and provides the perfect blend of modern and traditional styling. The high quality Flat Roof system is the most thermally efficient on the market with a U-Value of 0.12W/m2K (and is available with either flat skylights, roof lanterns or no rooflights).

The result is an absolutely stunning hup! extension that was built within a week! The extension fuses together an open plan kitchen with a dining area which has given the couple exactly the space they were aiming for. Externally, the hup! is finished in white render with anthracite grey windows, doors and trims for a stunning, timeless look.

The Ultraframe Flat Roof system is strong enough to span up to 5.6m unsupported above bi-fold or sliding doors without expensive and often cumbersome additional support, bringing style and simplicity to Flat Roof extension designs. All of the structural and thermal calculations are taken care of within the specialist Ultraframe design software which engineers the roof to the exact postcode of the property, ensuring that a hup! Flat Roof extension is equipped for the worst possible wind and snow loads at the build location.

The Ultrasky Lantern used on Mr & Mayfield’s hup! features 25% fewer bars than conventional glazed roofs and boasts ultra slim components for the ultimate in contemporary aesthetics. It’s also the warmest lantern on the market, featuring thermal breaks both inside and out and a thermally insulated eaves rail. This means that it is unrivalled in terms of thermal performance, ensuring a living space that is always a comfortable temperature, no matter what the weather outside.

Commenting about their new living space, the couple said: “We are delighted with our hup! extension, it provides everything we were hoping for. We use it all the time and it has given us a great flow through the house. We use it as a dining area but also, the piano is in that space and so we spend more time than just eating in there. With the bi-fold doors across the width of the extension, we can open it all up to the garden which provides an inside/outside living feel. The lantern on the flat roof also provides much more light than there was before. The build went up very quickly and it took a lot less time to complete than we would have expected. After the base level blue brick went down and the main construction started, we were “knocked through” and watertight within a week!”
