"Self-Build" and "Custom-Build" terms can be used interchangeably. But they are in fact different routes.

In this episode of the Self Builders Podcast, host Jack speaks to Helen and David about how a normal house search unexpectedly turned into a custom build journey. What started as a plan to buy a finished property in Henley-on-Thames evolved into an opportunity to work directly with a local developer to create a bespoke home tailored around their lifestyle.

The conversation explores the realities of custom build projects, including how much flexibility buyers actually get, how stage payment mortgages work, what decisions they could influence, and the importance of having the right professionals around you throughout the process.

Helen and David also share the lessons they learned around contracts, Community Infrastructure Levy (CIL) payments, landscaping costs, snagging, and managing the relationship with a developer while still ensuring the home truly feels like their own.

This episode covers:

• The difference between self build and custom build
• How they found their plot through a normal house search
• Working directly with a local developer
• What parts of the design they could and couldn’t change
• How stage payment self build mortgages work in practice
• Why they hired an independent surveyor
• Hidden costs people often overlook
• Managing budgets, specifications and payment stages
• The importance of clarifying responsibilities early
• What they’d do differently next time

If you like the idea of creating a more personalised home, but don’t want the pressure of managing a full self build project yourself, this episode offers a valuable look into a route that sits somewhere between a traditional house purchase and a full self build.
