Case studies matching "concrete lintels"

The former Marlow Railway Station dates back to 1873 and stood at the junctions of Station Road and Lock Road. The Old Coal Yard, adjacent to a station platform now only present, has been developed and designed by Bellwood Homes on the concept of three converted Victorian railway terraced buildings.Broadsman House, Palatine Place and Fenman Court consist of three 2-bedroom houses, eight 2-bedroom apartments and one 1-bedroom apartment providing commuters stylish suburban living. Keystones brick slip feature arch lintels and special segmental arch lintels encompass the traditional and contemporary balance of the housebuilders architectural vision.ChallengeThe fashionable commuter town on the Thames has been well preserved, limiting modern styled developments to maintain its original character and historic fabric of heritage buildings. Bellwood homes wanted a sense of purpose for their regeneration project – reconnecting people with what really matters to them, property location and design. The vernacular architecture provides both. A prime location for commuters to ride the branch line into London, renown as the ‘Marlow Donkey’, and fits subtly within the notable context of Georgian, Edwardian and Victorian styles of architecture in Marlow.SolutionKeystone’s technical engineer designed extra heavy-duty brick slip feature arch lintels for ground, first and second floor openings with a 1085mm span and 543mm rise. Over forty brick slip arches were manufactured by Keystone’s production team to a high quality and consistent finish. Each Hoskins Maltings Antique brick was cut to size and bonded using a BBA approved construction adhesive to the load bearing lintels. The patented perforated lintel design allowed the adhesive to squeeze through the perforations and form a ‘mushroom’ on the inside, providing a mechanical lock between the steel lintel and the brick slips.The offsite economical solution did not require skilled bricklayers on site to replicate each traditional arch. This saved approximately labour costs of one bricklayer per arch per day and ultimately weeks of the project build schedule. All prefabricated lintels were delivered to site and ready for final pointing in line with the phased construction plan of the three buildings being erected. The arches produced in a factory control environment were unaffected by torrential weather and winter reduced day light hours limiting productivity. This can often occur on other build schedules which lead to further delays in creating architectural features with real significance to the landscape.The offsite construction method facilitated onsite construction further by supporting bricklayers to recreate window tax designs, bricked up window spaces seen in buildings from the Victorian period. The detail of the façade is prominent most through the repetition of window arches positioned symmetrically on elevations facing the Marlow station. Keystones heavy-duty special segmental arches measuring a 2400mm span, with either a 600mm or 450mm rise provide a modern contemporary twist which feature above glazed bedroom windows and are in complete contrast to the smaller traditional arched windows striking a balance between old and new architecture.Testimonial“From R&D to installation we found Keystones prefabricated lintels very efficient. They reduce brick wastage approximately by 5%. Typically, traditional built arches would require one bricklayer for approximately six hours work. Therefore, this reduced labour costs on site whilst supporting bricklayers to achieve the desired architectural design.”Matthew McGillSite Manager at Bellwood Homes
