Self-build home: Prepare a detailed design
In this stage, we attribute design activities to ‘designers’. These may be architects and engineers, a design and build contractor, or a kit house supplier. If a kit house supplier is only supplying the house itself, additional design consultants may be required.
The detailed design process takes on and develops the agreed concept design. By the end of the detailed design stage the design should describe all the main components of the building and how they fit together, but the works will not yet have been defined in packages to obtain prices for construction. Detailed design should provide sufficient information to make building regulations applications.
The designer should co-ordinate consultations about the functional aspects of the detailed design with the self builder and should also co-ordinate consultations with the building control body. This may result in amendments to the design.
During the detailed design stage the designers may require input from the suppliers of goods and services that will be used in the construction of the building. It is important to ensure that pricing and contract conditions have been settled with these companies before any commitment to use their services is made, or it should be made clear that there is no commitment to use them for construction.
The designer will co-ordinate the incorporation of designs by specialist suppliers or contractors into the overall design and will source necessary samples of materials, components and assemblies for approval by the self builder. It may be appropriate to arrange visits to the specialist contractors' and suppliers’ premises to assess samples or mock-ups and to witness tests.
At the end of the stage, the designer should submit a full set of project drawings, specifications and a cost plan to the self builder for comment and approval before progressing to the next stage. For a full description of the aspects of design that might be developed during this stage, see Detailed design.
