📖 Buying Guide
When choosing Our Picks Garden Storage Boxes Under £300, consider these key factors:
- Size & Capacity: Measure your space first. Consider what you'll store - tools, bikes, bins, or furniture. Small sheds (4x3ft) suit compact gardens; large sheds (8x6ft+) work for workshops or extensive storage.
- Material Choice: Wooden sheds offer traditional aesthetics but need treatment. Metal sheds are durable and low-maintenance. Plastic/resin sheds are weatherproof and rot-proof but can feel less substantial.
- Weatherproofing: Check for proper roofing (felt, shingles, or metal), sealed seams, and raised floors. Good ventilation prevents condensation. Look for UV-resistant materials for plastic sheds.
- Security & Features: Lockable doors are essential. Consider windows for light, shelving for organization, and double doors for large equipment access. Check if a base is included or required separately.
