Summary Report combined concrete and timber framed prefabricated building components and systems.
Investigation of new and unfamiliar concepts, systems, materials and processes. Sources consulted Submission from the Irish Concrete Federation to the department of the Environment Heritage and Local Government. Proposed changes to part L of the building and Fire regulations. September 2007. Building Ireland RTE programme presenter Architect Orla Murphy.
Buildings visited a variety of timber framed dwelling units and a variety of concrete dwelling units. Achieved learning outcomes fast track prefabricated combined concrete and timber frame building systems for permanent dwelling units also adaptable to other building types.
Components and systems in storage more suitable shelter systems to replace tents, prefabs and metal containers in war zone and disaster area camps. High thermal and critical mass increased fire resistance reduction in energy consumption and co2 emissions helping to combat climate change.
Primary components, earthworks foundation excavation the only on site activity, prefabricated Gideon’s of three different varieties loose stone fill in steel mesh, sand fill in reinforced plastic clad steel mesh for earthworks and retaining walls. Foundation concrete and aggregate cast Gideon with exposed steel frame and interconnecting hooks clipped together and coated with plastic/silicone and rubber sealants to provide tolerance flexibility and earthquake resilient expansion joints vertical and horizontal up to ground floor level.
Party wall systems for terraced dwelling units and semi detached units similar to gunpowder storage system demonstrated on RTE programme Building Ireland. Example Carton Le Vert house Mac Gabhann Architects, an internal wall constructed using high density concrete blocks left exposed to provide a high degree of thermal mass. Omitting cut out opening this type of construction would be suitable as a fire resistant party wall providing critical and thermal mass for combined concrete and timber framed building systems.
Front, rear elevations and roof systems of prefabricated timber frame construction with triple leaf walls and double leaf roofs. Infill insulated double leaf timber frame walls between concrete party walls, externally clad with pre cast concrete panels creating a triple leaf walling system for the inclusion of triple glazing in window and door opes. Up to roof level where double leaf timber frame wall system extends to create a double leaf timber frame roof system to be clad with battens felt and slate.
Combined concrete and timber frame prefabricated building systems suitable for fast track housing developments required to combat Irelands housing shortage and homeless issues.
This design proposal will be constructed of timber frame as described above for my Edwardian apartment in Streatham inner London. This design can be replicated throughout London period terraced houses to provide additional two storey area, flood relief and wheelchair accommodation with access and increased parking provided through converting existing passages into dual accessible roads and services provisions.
