Real-World Use Cases & Scenarios

Scenario 1: Budget Garden Storage

Sarah wants a compact 3m x 2.5m cabin for tools and bikes. She picks felt flat roof, 28mm walls, no insulation, basic single glazing, and 'storage' use. The tool estimates £1,200–£1,800 (typical £1,500), explaining thin walls and basic roof keep it affordable.

Scenario 2: Premium Home Office

John needs a 5m x 4m all-year workspace. Opting for shingle apex roof, 70mm walls, high-performance insulation, premium double glazing, and 'home office' use yields £8,000–£12,000 (typical £10,000). It highlights insulation's role in comfort and value.

Scenario 3: Hobby Room Upgrade

For a 6m x 3m craft space, metal roof, 44mm walls, enhanced insulation, and standard double glazing gives a £6,500 typical – perfect for occasional winter use.
