The project entailed the development of ground and first-floor extension to Artek 4 Architect offices. New open plan drawing office to the first floor constructed with Light steel frame. Garage and storerooms to the ground floor in brick. This project was envisaged in LSF from the start. The client had previously worked with LSF building method and chose this option for speed of construction, green building attributes and wanting a mix of construction methods at their office expansion.
A brief description of the structural framing and cladding process
A standard frame-cad LSF lip channel section was used for all walls and roof structures. 90 x 40 x 0.8mm LSF Section. The building exterior cladding comprised of an OSB sub-board, Tyvek vapour barrier and 12mm fibre cement sheets. This was painted to seal the boards. Thereafter timber cladding was used, comprising of Timber battens running vertically at 400m centres. The final clad finish is Siberian larch in a T+G profile. All to create a stunning finish to the building.
Light steel frame was used for the floor joists, wall panels and roof trusses. Due to the lightweight structure, the client was able to use the existing foundations. The big glass shopfront opening and canter lever LSF floor required some additional design input and steel plating. There were no colossal challenges as the versatility of the LSF system provided some simple solutions.
A brief summary from the project given by the client “Somer Govender”.
“Artek 4 Architects Durban office is in the process of becoming part of a precinct named Green Houses located at 44 & 46 Lena Ahrens Road, Glenwood. The buildings constructed in the early 1920s are Edwardian Period in Vernacular style and Union Period, Berea Style house. The properties are neighboured by three historic “listed” double storey houses of Edwardian Period in Vernacular style, creating a mini-precinct of heritage buildings. The proposed additions are modest “clip on” lightweight steel and timber clad (FSI rated Siberian Larch) structures so as to not compete with the original dwelling and can be easily removed to bring the building to its original state. The intervention is based on minimal simplicity and honest materials of the period correct Bauhaus movement. When juxtaposed, the period styles enhance the character of the historic buildings but is also inclusive of the origins of modern architecture.
An inclusive process to ensure that the very essence that makes the historic building special is not lost. For the effective transformation from house to office, the design has considered the actual users which consist of a multitude of cultures endemic to our society. A variety of cultural inclusiveness is adopted in materials, patterns, colours and style in the building fabric. Much attention is paid to energy efficiency, water conservation/management and use of renewable materials and a Green Star process has been adopted.”
