Tom and Judy set out to build Cloud 8, a steel and glass statement house on an expensive Buckinghamshire plot. The vision was bold, but the ground was worse than expected, the foundations escalated, and the project quickly behaved like a prototype instead of a home. Tom chose to self-manage despite limited experience, negotiated every detail to the bone, and stacked risk on risk, complex geometry, specialist steelwork, and a roof concept so unusual most firms would not touch it. The result is a striking shell, but the route there is a masterclass in how ambition, pressure, and a knowledge gap can turn a self build into a long, expensive lesson.
