Kilnmead. It is the battalion headquarters of 103 Battalion, Royal Electrical and Mechanical Engineers. The building also houses an Army Careers Information Office. Heritage Three of the 100 listed buildings and structures in the borough of Crawley are in Northgate. Boscobel House is at the south end of London Road close to where it becomes Crawley High Street, very close to the former Northgate tollgate. The building, which is now an office, was built as a two-storey timber-framed cottage in the late 17th century and was given a brick and tile façade a century later. The roof is also tiled. Black Dog Cottage is a 16th-century farmhouse which retains its original timber framing, although it was given a brick façade in the 19th century. Another original feature is the chimney, which sits on the steep tiled hipped roof. The rear elevation is weatherboarded. Fir Tree Cottage is another timber-framed building, although it is later: it was built in the late 17th or early 18th century. By 1792 it was in use as the Crawley parish workhouse. A mixture of brickwork, tiles, stucco and exposed timberwork can be seen on the exterior of the building, which (like Black Dog Cottage) is now a private house. It is on the east side of London Road. There were 59 locally listed buildings in Crawley as of 2010, including one in Northgate. Dyers Almshouses are a "charming" complex of single-storey almshouses designed in the Arts and Crafts style by architect W.H. Hatchard-Smith of the Bertram & Co. firm in 1939–40. Their prominent tiled gables are "reminiscent of rural Dutch cottages", and each is topped with a large chimney. Only ten of the houses, which are set in a quadrangle around a garden, are original; another 16 were built to the same design in 1952, and four more were added in 1971. They were among the many buildings built in Crawley and the surrounding area by local building firm James Longley and Co. The buildings are also part of the Dyers Almshouses Conservation Area, one of 11 conservation areas in the borough. Transport Metrobus route 100, part of the Crawley Fastway network, runs through Northgate along Woodfield Road, calling at several stops in the neighbourhood. The route serves Maidenbower, Three Bridges, Crawley town centre, the Manor Royal industrial estate and business district, Lowfield Heath, Gatwick Airport and the Surrey towns of Horley and Redhill.
