Garden room in super efficient home

An ambitious project by a Wiltshire couple, wanting to convert an unused void beneath their ultra-modern home into a comfortable garden room, has included the installation of our Hydronic underfloor heating system.

When the super energy-efficient home in Marlborough was constructed in 2014, we were contracted to lay its Hydronic pipework throughout the 4,000 square foot, two storey structure. Two years later, though, the owners decided to open out the space which was effectively a sub-basement built into the rising ground of their back garden; and again called on us.

The project was made challenging not only by the earthworks and structural alterations required, but also the property’s near-passive energy performance with heating and hot water demands being met by an exhaust air source heat pump.

Owner Keith Fryer takes up the account: “The garden slopes quite steeply down to the back of the house and, although one area intended as a cinema room had been given a small window at high level, the space which backed onto the kitchen had no natural light and was an empty void.

“A central supporting wall had to be replaced and hundreds of tonnes of soil removed for us to open up the space with sliding doors but it now provides us with a 400 square foot garden room, linking to the kitchen, which we can use all year round. In terms of the heating, we approached Gaia as the original installer and were very impressed with their expertise, the layout detailing provided, and the competitiveness of the quote. We felt Gaia was the right company to go with, while the installation team did a really good job, coordinating with our other sub-contractors. The combination of underfloor heating and the concrete floors – above and below – is also ideal in that it allows the warmth to ease out into the occupied rooms. The project came in on time and within budget -It all works extremely well.”

In addition to providing design calculations and extending the heating loops into the new garden room, we also increased the size of the existing manifold to facilitate the alterations.

We’re able to offer commercial specifiers, as well as self-builders and other residential clients, a wide selection of hydronic and electric underfloor heating options to suit the demands of new or refurbishment projects, including those in off-gas areas.  We provide comprehensive technical and logistical support whatever the scale of the contract, the contact us email or complete our contact form
