Heritage Style Doors

heritage style patio doors with black slimline aluminium frames, set into red brick wallSteel framed heritage doors typically feature square or rectangular panes of glass, divided by slim metal frames. These are the classic art deco windows seen on many London buildings from the 1920s - 1930s. They have a minimalist, industrial look and are often used internally and externally to divide spaces while still letting through plenty of light.

Since the end of the 19th century, steel framed windows and doors have been a familiar site on industrial and residential buildings throughout the South East of England. In fact for many decades, the county of Essex was renowned for manufacturing steel-framed windows and doors.

During the 1920s and 1930s, slimline steel framed windows became widely associated with modernist and Art Deco architecture.

Heritage windows and doors are again becoming increasingly popular in London homes due to their sleek, modern design and ability to maximise light in smaller spaces. This classic style blends extremely well with local architecture throughout London and the South East. Also, because the style and materials originated nearby in Essex, installing this style of industrial heritage windows enhance your property and maintain strong ties to British design.

Minimal Frame Projects offers a full range of heritage windows and doors for both internal and external use. While retaining the classic British style, the updated aluminium frames provide you with all the benefits of thin, lightweight construction, enhanced security, and high thermal insulation.

Our modern aluminium industrial style steel framed windows and doors are custom made to your specifications. They are available as fixed windows, single/double sash, top-hung, tilt & turn, pivot windows, bifold doors etc... the list goes on.
