Keystone brick slip feature lintels integral to Cheshire barn development
restoration and conversion of a series of barns into new homes along with the creation of nine new build houses. Church Farm Barns in the village of Acton
K
in Cheshire is located in a conservation area near the market town of Nantwich. The scheme, delivered in two phases, has seen the restoration and conversion of three barns and a six-bed Grade II-listed Georgian farmhouse along with the construction of nine new-build two, three and four-bedroom homes. Built by Chamberlain Developments, the second phase of the project required brickwork design for the new-build homes, which was in keeping with the heritage sensitivity of the site and adjacent barns and farmhouse. The specification required a number of unique, one-piece brick slip feature lintels which were designed by Keystone’s technical team and manufactured in a factory
eystone Lintels has provided a range of innovative, prefabricated brickwork solutions as part of the
controlled environment negating the need for complex brick cutting on-site. The nine new-build homes feature a combination of eighty bespoke Flat Gauge Brick Slip Feature Arches, as well as Bullseye and Parabolic Lintels, each requiring a flawless brick surround finish to match the brick being used on-site and in keeping with the appearance of the converted barns. Fabricated off-site, Keystone’s dedicated technical team ensured each bespoke lintel was manufactured to the size, shape and aesthetic requirements within the project build schedule. Keystone collected a consignment of
bricks from the developer to ensure the brick slips matched the ones being used on site. These were then cut and bonded onto load bearing lintels using a BBA approved construction adhesive. The patented perforated design of a Keystone Brick Slip Feature Lintel allows the adhesive to squeeze through the perforations
and form a ‘mushroom’ on the inside, providing a mechanical lock between the steel lintel and the bricks. The plans received from T G Builders
Merchant originally included brick slip lintels for the front and rear elevations only however, Keystone’s team were able to offer Chamberlain Developments a solution for the other more intricate brick details and the specification was therefore increased to include additional brick slip flat gauge arches and bullseye lintels for the side elevations.

47 is the new 50 – have you switched yet?
To build safer, stronger structures requires more than just top quality joist hangers; equally important is choosing the correct sized joist hanger. Regularised timber is now the UK standard, which means 50mm hangers are yesterday’s news. Unlike rough sawn timber, where the width of a joist can be anything up to 50 mm, regularised timber is planed down and the edges rounded for consistency, so regularised timber is always 45 mm. At Simpson Strong-Tie we know that size matters! Regulated hanger sizes have long been offered across our hanger ranges. National builders merchant sales manager Steve Allen explains: “Our 47 mm range provides the correct, secure fit. Using 50 mm wide hangers leaves a gap between the hanger and the joist, which not only requires structural packing in order to meet regulations, but can still result in twisting timber and squeaky floors. The wider the hanger, the more important it is to use regularised sizing – and Simpson offer it as standard. We have 47 mm hangers for singles joists, 91 mm for doubles and 137 mm for triple joist applications.”
