Upper Dolfor Road
A self-build six-bedroom detached property, nestled in rural Powys overlooking both the Severn Valley and Newtown. Using aircrete, a certified modern method of construction, main contractor B W Bellis was able to complete the blockwork on the large six-bedroom property within six weeks. Apart from some technical assistance from H+H on working with aircrete, all of the block work was laid by a single worker during this time.
Nelson Project Homes for Veterans
H+H Celcon Blocks were specified for use on a 24-unit social housing development in Plymouth. H+H was chosen in part due to the lightweight properties and ease of use of the product as half of the units were constructed by veterans, many of whom had never worked on a construction site before.
Flockton Self-Build - West Yorkshire
H+H Celcon Blocks were specified in Brian Green’s self-build project. His property was constructed with the aim of being as thermally efficient as possible. Special attention was paid to detailing of the insulation, thermal bridging and envelope penetrations. Due to planning constraints, the build had to be sensitive to existing adjacent residential properties which are 200-400 years old.
Severn Vale Housing Association, Gloucestershire
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.
Batheaston Primary School
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.
Stondonfield Homes, Essex
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.
Lime Tree Lodge
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.
Elme Hall Hotel, Cambridgeshire
A new extension to the hotel created using Celcon Blocks with traditional mortar and cavity wall insulation. Demolition of existing outbuildings of the Elme Hall Hotel, followed by construction of a 34 bedroom building. Being a hotel, acoustic considerations were of paramount importance as was robustness of construction materials.
Orchard Close, Wales
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.
Norton Farm - Celcon Elements
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.
Bourne End, Bucks
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.
Sawston College, Cambridge
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.
Princess of Wales Hospital, Bridgend
Built as a 19 bed mental health facility for young people built on the Princess of Wales Hospital site, Bridgend. Construction was managed by ABMU Health Board with the facility run by Cwm Taf Health Board. It accommodates patients from across South Wales and is a mixed sex unit, caring for young people.
Three Oaks, East Sussex
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.
Orchard Field, Ashford, Kent
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.
