Planning your own grand design: a step-by-step guide

Building a one-off home is a huge undertaking, and the decisions you make in the first few months have the biggest effect on cost, quality and how much you'll love living there. Here's how a design-led self build comes together.

1. Understand the plot before you buy

Check the planning history, constraints such as Green Belt or a conservation area, access, services, ground conditions and trees. A feasibility study before you buy can save a great deal of money and heartache.

2. Write the brief around how you live

Before thinking about style, think about life: how you cook, entertain, work, relax and grow older. A good brief is about the rooms you need and how they connect, not just the number of bedrooms.

3. Concept design and 3D

Explore options in plan and in 3D. This is the cheapest point to change your mind, so take your time and test the ideas properly.

4. See it before you build it

Photoreal renders let you walk around the finished house, check views and materials, and share the design with family, neighbours and the planning officer.

5. Planning, then technical design

Secure planning permission, then develop the building regulations drawings with your structural engineer. Add a tender package so builders quote on exactly the same information.

6. Choose your builder carefully

Compare like-for-like tenders, check references and agree a clear contract. Contract administration can protect you during the build.
