Standard Fees

With a typical extension the work and fee is split into two parts, the planning drawings and the building regulations application.

Planning approval drawings  / full scheme drawings £350

Based upon a typical 1-2 storey house extension / attic conversion including paper copies, OS maps, all initial on site surveys and pre-start meetings. 

This includes a draft copy of your proposed extension to make sure we have interpreted what you want correctly before completing the final design stage.
Initial plans drawn up typically within 2 weeks

If the proposed works require a submittal for planning approval, a fee is then payable to the planning authority upon application, and this currently stands at £150

Building regulations drawings/calculations £350 (following on from the planning / scheme drawings)

This includes all required structural design calculations carried out to the latest regulations (steel beams, foundations, ground floor slab design, roof truss layout, floor joists, purlins etc)

There are no hidden charges for design work

A fee is also payable to the local authority building control upon application, and this varies upon the size of the proposed works, but typically around £130-250

Extended Design Limited carry out all of the paper work.  All you are required to do is make the appropriate cheques payable to the relevant local authorities, we do the rest

Invoices are not issued until the appropriate work has been fully submitted to the local authorities

If your proposed extension falls into 'Permitted rights to build' and you only require a Building regulations package then the fee payable to the council of £150 is not required. 

Extended Design Limited does not currently charge VAT
