Our Process


Preparation of your project, feasibility and objectives for the project. Once this has been achieved we can carry out any surveys and gather the information needed to proceed.

Concept Design

Concept design will include sketch schemes of your proposal and will allow us to make alterations and finalise your project brief. It will give us an outline for the structural design, building services and outline specifications of the project.

Developed Design

Finalising your project design and preparing any permissions required including planning permission and permitted development applications. Your project may be works to a listed building or perhaps in a conservation area or AONB (Area of outstanding natural beauty) The developed design is used as a basis for such permissions and applications.

Technical Design

Following our project strategy, the Technical Design will include building regulations specifications and  construction drawings, structural engineering calculations and design and a handover strategy to the contractor. This stage will enable us to apply for building regulation approval and other permissions including building near drainage on your behalf.
