RSA Architects has a proven track record for imaginative design across a diverse range of building types and offers a professional service to clients from feasibility study to the completion of building work. Sketch designs are produced through 2D and 3D visualisation or modelling for discussion with clients and planning authorities for new individual buildings, re-development sites, multiple housing projects, conversion of existing buildings, refurbishment and major extensions. The final presentation of the building proposals, for submission to the planning authorities, is illustrated in top quality 2D drafting backed up by the latest technology in 3D visualisation. For infill sites, new designs are shown in context either through hand drawing a perspective of the s t r e e t scene, superimposing the cad design onto a photograph, or preparing a 3D model. The design can then be readily understood and observed with the local environment context.
