These are comprehensive, step-by-step build plans for a 4.2m x 2.4m (10m²) garden room office featuring a warm roof construction and 2.8m overall height.

The design was developed and refined during the construction of my own building — not drawn in isolation, and not generated from generic templates. Every detail has been considered from real-world experience, with a focus on structural clarity, material efficiency, and long-term durability.

This size provides a practical and comfortable workspace, suitable for a generous single-person office or a compact two-person setup.

What Makes These Plans Different 

• Designed and built in practice — not theoretical
• Carefully optimised material sizing to reduce waste
• Warm roof construction with clear condensation strategy
• 2.8m overall height for improved proportions and internal feel
• Logical build order to reduce mistakes and rework
• Clear drawings and written guidance throughout

A significant amount of time has gone into making these plans detailed, accurate, and genuinely easy to follow. The aim is not just to show what to build, but to help you understand why each element is constructed in a particular way.
