How do system integrators make money?

Approximately 7% to 10% of all new housing completions in the UK are custom built or self-built homes, according to Wilson (2017). In 2020, data from the Ministry of Housing, Communities & Local Government (MHCLG) indicated that around 15,000 homes were either self-built or custom-built annually, representing a significant 50% increase over just two years. This growth reflects a rising interest in personalized housing options and a shift towards more flexible, owner-driven construction processes. While the percentage may seem modest compared to total housing completions, the rapid increase highlights a notable trend towards greater consumer involvement in the design and building of their homes, contributing to a more diverse housing landscape across the UK.
