After planning approval is granted, we move onto the construction drawings/ pre-commencement conditions drawings. At this stage, Lees Architects will consult with any relevant specialists that are required for the project. This generally includes, at a minimum, a structural engineer, however, the complexity of the project may require more consultants many of which, Lees Architects have previously worked with and can recommend. Specialists may also be required for pre-commencement conditions, which need to be approved by the planning department. Pre-commencement conditions usually apply to new build schemes only. Once construction drawings are completed a Specification of works can be written up to accompany the drawings for the tender process. The tender process usually occurs whilst Building Control is reviewing the scheme.
It generally depends on the size of the project. However, for a new build 150 m2 house, the following will generally apply.
1.Construction Drawings/ Conditions drawings- 3 weeks
2.Condition application- 2 months
3.Tender documents (whilst condition application is processing)- 2 weeks
4.Building control process (whilst condition application is processing) – 3 weeks
Lees Architects will advise on all necessary specialists required to complete the project successfully. For an extension, in addition to an architect, the only additional consultants that will be necessary are a structural engineer and Building Control, however, a new build project will generally require the following:
