2. Application for Building Regulations Approval
Further to the Planning stage, a Building Regulations application will need to be made to the Local Authority Building Control department.
Technical survey of site
A survey will be undertaken to cover any areas not surveyed for in the measured survey.
Building Regulations Plans, Sections and Construction notes
A preliminary set of plans and notes shall be prepared for discussion and any amendments can be made.
Preparing and submitting the Building Regulations Application
We will require a cheque payable to the Local Authority as the application fee** and also settlement of the balance of our fees. We will then submit the application using the preliminary drawings to the local authority for consideration and if necessary to a structural engineer and/or a heat loss assessor for them to provide us with a quotation for their services.
**Building Control fees vary depending on the extent of the work proposed. For an extension up to 60m2 the fee is typically £650.00.
Instruct Engineer
We will receive a quotation for the engineer for their calculations and they will need to be instructed by you to proceed.
Revised plans
Once we have heard back from the Building Control Officer, we can make any neccessary amendments, give additional details if requested and resubmit the revisions along with the structural calculations etc.
