How we work

One architect from survey to site

Our project management covers the whole process, from the first look at your building to supervising the work on site. We follow the building regulations throughout, so the work is safe, economical and environmentally friendly.

Project management

  1. 1

    Survey the building

    We look at the existing building's shape, condition and character, and talk through your budget and timescale.

  2. 2

    Outline drawings

    We prepare outline drawings of the design for you to comment on, in 3D where it helps you picture it.

  3. 3

    Planning application

    We submit the planning application and handle the planning permission, including any party wall agreements.

  4. 4

    Drawings, schedules and contracts

    Detailed drawings, plan schedules and building contracts, to the building regulations, plus local builders we recommend.

  5. 5

    Supervision on site

    We attend site and supervise the building work through to the day it is ready to use.
