Extension design

Design your dream extension

Our design process uses the latest technology and our deep understanding of how to design Pinterest-worthy extensions that can be built with regular budgets.

How it works

Home consultation

We’ll come to you, talk through how we’ll create the new heart of your home, and very importantly discuss build costs straight away so you are confident of the project’s viability.

Architectural drawings

We’ll measure up so we can create your final design. Within three to six weeks, you’ll receive a full drawings package including the block plan, the location plan, elevation drawings and detailed floorplans.

Build Costs

We’ll give you detailed costs using our own software to calculate them accurately. We strongly believe in ensuring your design meets your budget.

Planning application

We take care of any red tape, making the application on your behalf and dealing with any planning queries via your local authority who will take around 8 weeks with your application.

Let’s build!

Once your approval is granted, we’ll manage everything: building regulation plans, structural calculations and building control. And of course, we’ll assemble your build dream team.
