Helifix features in Episode 14 of Grand Designs, Series 7!
It looks at the planning and development of Hill Barn/Underhill House in the Cotswolds at Barton-on-the-Heath in Gloucestershire. Despite being constructed on a prominent hill top site in an Area of Outstanding Natural Beauty, the whole of this strikingly modern house is below ground level and invisible from the surrounding countryside.
A principal condition of the property’s planning permission was that an ancient stone barn on the site must be retained. Although in a very poor condition, the barn was to be structurally repaired using the Helibeam System, underpinned and then supported on a steel frame while the house was constructed in excavated ground beneath it. The barn, which has now become the office of the owner and architect of Underhill House, Helen Seymour of Seymour-Smith Architects, would then be the only visible part of the project.
Constructed from rubble-filled Cotswold Stone walls, some 600mm thick, the decaying barn was unstable and needed to be fully stabilised to protect it during the construction of the new subterranean house and to reinstate its structural integrity for its future life as part of the new dwelling. Using a scheme designed by Helifix engineers, the local Approved Installer, Cotswold Structural Services, consolidated the rubble filled walls by installing 140 grouted CemTies in order to allow the installation of 340m of Helibeam reinforcement to create ring-beams around the structure. Where existing window and door openings were present these were temporarily blocked up to permit continuity of the HeliBars, which were later cut and embedded into the reveals.
A further reason for granting planning for this outstanding development was that it is the first registered property in England designed to Passivhaus standards. This method incorporates very high levels of insulation, super-insulated triple glazed windows orientated to the south to maximise passive solar gain and an incredibly well sealed building fabric. Using the Passivhaus construction method should result in a 90% reduction of carbon emissions, compared to that of an average home, and, by adding renewables, Underhill House will also be carbon neutral.
Helifix is proud to have been involved with this outstanding and unusual property which has employed the best methods and materials at all stages of its development.
Restored Grade II listed engine house

Restored Grade II listed engine house becomes a working museum
Built in 1886 and closed in 1964, a Grade II listed engine house at the former Tottenham sewage works in the London Borough of Haringey was suffering from cracked masonry and failed arches. It has now been made structurally secure, using Helifix masonry repair products, fully renovated and turned into the Beam Engine Museum. With its restored and operational Wood Bros. Beam Steam Pumping Engine forming the principal exhibit, this local heritage museum provides an interesting focal point for the regenerated and landscaped Markfield Park.
When the site was closed in 1964 the large arched windows of the engine house were bricked up to prevent vandalism. Before these bricks could be removed and the windows reinstated the arch lintels had to be secured using grouted CemTies which were installed through the arches and into the brickwork above by Helifix approved installer, Bearings Structural Repairs.
The building also had various vertical cracks in the masonry, many as a result of vibrations caused by the operational beam engine. To repair the brickwork Bearings installed the Helibeam System which involved grouting over 300m of stainless steel HeliBars into different mortar beds above the arches. These secured and reinforced the masonry, stitched cracks and redistributed the loads to restore full structural integrity.
Helifix systems were specified by NPS Property Consultants as they are fully proven, can be rapidly installed, thereby avoiding any delays on site, and are fully concealed, so did not alter the visible appearance of this Grade II listed museum.
