01
Initial Consultation
Let’s talk about your project
Tell us what you’re hoping to achieve, ask as many questions as you like, and we’ll explain the options available for your property. Together we’ll recommend the best route forward before any design work begins.
02
Site Survey & Design Brief
Understanding your home
We survey your property, take accurate measurements and discuss how you want the space to work. This gives us the information needed to create a design that’s practical, compliant and tailored to your home.
03
Design & Planning
Developing your proposal
We’ll prepare your design, refine it with your feedback and produce everything needed for Planning Permission or Permitted Development where required, making sure you’re happy before moving to the next stage.
