Self-Build and Custom Build

Available to self-builders who want to buy a plot of land to build a new house or refurbish an existing structure for their own occupation.

What is custom build?

Custom build homes are self-built homes that are facilitated by a professional developer. They offer the chance to have a unique property that suits an individual’s lifestyle and preferences but minus the high degree of involvement associated with traditional self-builds. Custom building can describe a single one-off home commissioned by an individual and built by a developer, or a group of homes built by a developer but offering the future occupants the chance to tailor the design.
