Built on experience
It started on site.
It grew into
a mission.
William’s experience began in 2007, working on portal-frame buildings. Site work led to construction management, engineering drafting and estimating.
MBA brings those lessons together with one clear aim: make well-designed shed homes easier to understand, design and bring to life.
- Practical knowledge.
- Customer-led design.
- A clearer way forward.
