H+H UK Ltd

Bottle Lane is a private custom build home designed and constructed by Revolution Homes. The four-bedroom, detached house stands on the site of the client’s old property which was demolished to make way for a new more acoustically and thermally efficient build. As the client was overseas for the duration of the build, they wanted a company that could offer a full system build package from conceptual design to a finished product. Specialists in the custom-build market, Revolution Homes was able to supply this by employing the H+H Rå Build method of thin-joint aircrete construction.

When regional housebuilder, Galion Ltd was looking for a way to speed up the construction process without compromising on using traditional masonry materials for its Jarmany Hill site, it turned to H+H’s Celcon Vertical Wall Panels.Celcon Vertical Wall Panels are storey-high panels of aircrete that are craned into place for a fast build with the reassuring characteristics of a high-performance, durable, masonry structure.Galion Ltd is building five large, detached houses with uninterrupted views over the Somerset countryside towards Glastonbury Tor. With a reputation for building individual properties to a high specification, the quality of the build is a strong focus for the company.Tim Barnes, Managing Director of Galion Ltd explains why H+H Vertical Wall Panels were chosen for the site: “One of the unique features of our houses is that we use local, natural stone walling for the external envelope of the properties. These are slow to build, especially when we’re using a traditional masonry build method as we are restricted to a maximum of six courses before laying the masonry to the same height.“With the traditional method it was taking 8 to 12 weeks to get to the point where we could put the roof on a house. The joy of using H+H Vertical Wall Panels is that we can get the roof on in around 8 days – it’s a huge advantage for us.”Constructing the watertight external shell of a house so quickly allows the internal trades to start work much earlier, reducing the build schedule significantly. When building large homes like the 2,800 square foot houses on the Jarmany Hill site, this time saving is particularly pertinent.Galion Ltd is working with Acorn Innovation Build Ltd whose carpenters were trained by H+H to install the Vertical Wall Panels. It was a fairly straightforward transition for them as they already use a crane to install timber floor cassettes and roof joists.Matt Shuttleworth, Director, Acorn Innovation Build commented: “H+H Celcon Vertical Wall Panels is a new system for us but as a company we are always interested in different methods of construction. I have to say, so far we are very impressed with this one.”Tim Barnes is equally impressed, saying: “I’m struggling to see a downside to the system. Everyone who has seen it has been impressed and I think once other companies see contractors building with it they’ll wonder why they’re not using it too. We’re already planning to use the system at another site that will be breaking ground soon.”

The I-House System, incorporating Celcon Vertical Wall Panels, has been specified for use on 164 units of the Norton Farm site in Bromsgrove. The I-House system, a collaboration between Roofspace (formerly SIG) and H+H UK provides the speed of offsite construction with the familiarity of a traditional build.

A prestigious development of five luxury apartments constructed toPassivhaus principles using the H+H Thin-Joint System.Masonry Frame Systems specified H+H Jumbo Bloks primarily because it is what was needed to meet the demands of this Passivhaus construction. H+H Jumbo Bloks offer an advanced thermal performance which adheres to Passivhaus standards.The Thin-Joint system was chosen in particular for its speed of construction, which allowed follow-on trades to start work sooner in a weatherproof environment, whilst retaining the flexibilityof on-site construction.

The full I-House system package was used for each unit, comprising the structural inner skin, insulation, floor cassettes, roof cassettes, soffits and facias. The I-House system is manufactured offsite by Roofspace Solutions who also supply a 3-person team and crane operator to create each structure. 

Charlotte and her family have always enjoyed living in their Edwardian terraced home in Wimbledon, although after spending lockdown with their two young daughters, they realised they needed more indoor space. The couple decided to complete a rear extension to create more space. Built using H+H Celcon Blocks the extension has made the house noticeably warmer and improved the sound insulation.The finished extension houses the kitchen and dining area, as well as a large corner sofa. Charlotte notes, “I’m actually pursuing a career in interior design, so I worked closely with Westminster Building Company to ensure the space is both warm and inviting. My partner and I love cooking and dining in there now, and our kids certainly enjoy the extra space.”“H+H is a big name, so I didn’t give it a second thought when using their Celcon Blocks. I knew I was buying good quality building materials that are light to handle and easy to use.” “Technically speaking this was a job that required some forethought, as the homeowner wanted the extension to be future proofed for building up a storey. Also, one of the next door neighbours was planning for a rear extension to their home. “This meant that we built a 300mm wall with two layers of 100mm Celcon Standard Blocks (3.6N/MM2) with a 100mm cavity wall insulation and used Celcon Block High Strength Grade (7.3N/mm2) on the inner skin. This was both to facilitate future upward building and to ensure that the neighbours plans weren’t mitigated.” Will Clark, Director, Westminster Building Company.The floor to the extension was created using an Insulated Beam & Block construction, using Celcon Block Standard Grade 100mm blocks.
