Case Studies

Passivhaus is achieved by the application of high levels of insulation, avoidance of thermal bridging within the structure, low levels of air leakage all of which are qualities addressed with the use of the H+H range of Celcon Blocks.  Faced with both brick and timber the bungalow has an external U-value of 0.096 W/m2K for the timber faced walls and 0.098W/m2K for the brick faced walls.

Cameron Close is a Passivhaus development of 16 semi-detached houses and 12 sheltered accommodation apartments for Southern Housing Group in the rural village of Freshwater, Isle of Wight.

A prestigious development of five luxury apartments constructed to Passivhaus 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.

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

An Eco friendly extension to this Primary School,built using H+H High Strength Celcon Blocks and Celcon Plus Blocks. Batheaston is a ‘Green Flag’ awarded primary school and is part of the international ‘Eco-Schools’ programme.The school was assessed to ensure it met the Green Flag checklist.

Using the H+H Rå Build method of construction, this mix of 1 and 2 bedroomed apartments was built to provide case and support for independently living people with special needs.

Stondonfield is a contractor led social housing scheme whereby Collins and Beckett found the site and put together a complete package for the end client. It took a couple of years to get the project through planning due to objections by the local parish council that the land was outside allowed development areas.

H+H UK’s Plus Blocks using the Thin-Joint system meet the acoustic requirements internally and thermally insulates the external walls for a fast-track construction programme. After using on the first phase, this construction provided the advantage of speed against phase two’s summer holiday deadline.

An entirely new house was built to accommodate the preferences of the family. An integral office replaced the original garage, a large kitchen provides living space for the family and the rooms in the roof give privacy and space for the daughter of the household. The client opted for thin-joint construction in order to capitalise to the maximum on the energy efficiency of aircrete construction.

This was phase two of a multi-staged project to build new council homes on existing council-owned land. Typical sites for the project included disused garages and areas of waste ground between developments. The dwellings were all built to Code Level 4 of the Code for Sustainable Homes. Although in advance of the existing building regulations, this objective fitted with the government aim of encouraging government agencies to increase standards of sustainability.

To achieve this rating, the construction elements needed a high level of thermal insulation. The Rå Build method using the H+H Thin Joint masonry system was specified using Jumbo Bloks. Fully filled cavities were combined with either aircrete or brick outer leaves. This is not only an extremely fast and efficient method of building, but also provides substantial benefits in reducing heat loss. In designing the wall structure, the use of aircrete’s very low psi values, based on Accredited Construction Details, allowed a halving of the y-value from 0.08 to 0.04 W/m2K. This is used to calculate the impact of linear thermal bridging within SAP 2005. The 0.04 y-value is achieved by virtue of the thermal efficiency of aircrete, without the need to resort to Enhanced Construction Details, and has a similar effect on all external elements.

Badby Park is a unique facility dedicated to neurological illnesses and disorders, providing specialist nursing and rehabilitation in the vicinity of Northampton.

A four storey development built with H+H Multi Plates, using the Thin-Joint method of construction.

Celcon Plus blocks (610 x 215, 200mm thick) with the Thin-Joint System were used to infill the reinforced concrete frame of this development in Hackney.

A mixed-use development using H+H Jumbo Bloks with Thin-Joint technology, creating 114 homes.

Contractor R G Carter wanted a construction solution that was more adaptable than a timber frame system, which would allow late design changes to be incorporated into this innovative housing development without too much difficulty.

Craven Gardens is an exclusive development of eight detached four and five bedroom homes set in the gardens of a former hunting lodge located in the historic market town of Melton Mowbray, using Jumbo Bloks and the Thin-Joint System.

Cawrey Homes’ Fielding Meadow development is made up thirty two 2 and 3 bed semi-detached and four 4 bed detached homes. All the homes are built to level 4 of the Code for Sustainable Homes.

These show homes by Crest were built using the Rå Build method of construction, ensuring a quicker than usual build time.

New sustainable neighbourhood designed by Terence O’Rourke. Within this 6.9 hectare site to construct 430 dwellings aimed at first time buyers will provide new homes, an attractive open park and school with useful transport links for the local community.

A three-storey building comprises 21 one bedroom and 3 two-bedroom apartments, as well as secure parking facilities with 17 car park spaces.

Known as the 'Miller Zero' project, the development was built for real customers, as well as a project to take its supply chain, on a journey towards Code level 6 on the 3.65 acre site.

28 new houses built by Wates. The development made use of the Rå Build method of construction throughout and incorporated the 1000th home built using this method.

A mix of social and private homes, using the H+H Rå Build method of construction.

Contractor Robert Bishop from RT Bishop, required a swift construction solution as a replacement for timber frame that his team could successfully use to deliver the project on time. H+H’s Rå Build method, using the Thin-Joint System and a combination of H+H Jumbo Bloks and Celcon Foundation Blocks provided the perfect solution.

A new Self-Build Bungalow built using the Rå Build method from H+H.

A private one-off custom-build residential home built for a family of four who had lived in Bourne End since 1985. They wanted to buy a new house in the area, having extended their existing bungalow three times, but could find nowhere suitable. This led them to look at custom building a new home on the existing bungalow’s plot.

A four unit apartment block in an in-fill site. Built using the Thin-Joint method and Jumbo Bloks.

Having used H+H’s Thin-Joint System for more than 10 years, Sherborne Homes again opted for this effective build system when working on their very first housing association project. The Thin-Joint System provides the Sherborne Homes contractors with a hassle free building solution and a great support package that allows for fast and effective construction. It is the tendency of Sherborne Homes to steer away from using timber frame and H+H products offer the perfect solution.
