📏 1. Choosing the Right Size

Think About What You’ll Store

Before buying, measure the items you plan to store. Typical storage needs include:

• Garden tools
• Lawn mowers
• Bicycles
• Plant pots
• Outdoor furniture

Suggested Sizes for Common Uses

📌 Measure first: Always measure your garden space before ordering to avoid surprises.

📐 2. Shed Placement Tips

Where to Put Your Shed

• Away from low spots where water pools
• Near paths for easier access
• Against a wall or fence to save space
• Allow airflow around the shed to reduce damp

📏 Keep at least 3–6 inches clearance on all sides.

🧱 3. Shed Bases — The Foundation of Longevity

A good base is essential. It keeps your shed level, prevents moisture, and improves structural stability.

Best Base Options

✔ Concrete slab base — Most durable
✔ Paving slabs — Great balance of cost & performance
✔ Timber bearers on a firm level surface — Easier on soft ground
✔ Gravel base — Works when well compacted

Base Size Tips

• Make the base 10–20 cm larger than the shed floor area
  (e.g., a 6×4 ft shed should have a 6′2″ × 4′2″ base)
• Ensure the base is level — use a spirit level

🏠 4. Roofing Styles & Weatherproofing

The roof protects everything underneath — so consider material, slope, and strength.

Roof Types

🔹 Apex Roof

• Peak in the centre
• Excellent rain runoff
• Great headroom inside

🔹 Pent Roof

• Single slope
• Lower profile
• Good for tight spaces

🔹 Reverse Apex

• Doors on longer side
• Better access in narrow gardens

Roofing Materials

• Felt roofing — affordable, common, decent protection
• Metal sheets — extremely durable
• EPDM rubber — long-lasting and waterproof
• Shingles/tiles (for timber sheds) — stylish and effective

📌 For rainy climates, ensure good water runoff and sealed edges.

🔐 5. Shed Security — Protect Your Gear

Security is essential, especially if storing expensive tools, mowers, or bikes.

Top Security Features

🔒 Reinforced doors & frames
🔒 Lockable handles / padlock hasps
🔒 Internal hasps to hide locks from view
🔒 Bolt-down kits to secure the shed to the base
🔒 Hinges with non-removable pins

💡 Tip: Use security lights or motion sensors near sheds in open garden areas.

🧰 6. Materials & Their Strengths

Resin / Plastic

✔ Weatherproof & rot-proof
✔ Very low maintenance
✔ Good for wet climates
✘ Less secure than metal

Metal

✔ Excellent strength & security
✔ Rust-resistant if coated
✔ Long-lasting
✘ Needs ventilation to prevent condensation

Wood

✔ Traditional look
✔ Easy to customise
✔ Can be strong when treated
✘ Needs annual preservative treatment

🧩 7. Door & Access Considerations

Choose Doors That Suits Your Needs

🚪 Single door — Fine for small sheds and occasional use
🚪 Double doors — Easier for bikes, lawnmowers, wheelbarrows

Threshold Tips

• Use a low threshold for easy rolling in/out
• Ensure doors seal properly to keep out rain & drafts

💨 8. Ventilation & Condensation Control

Good airflow helps reduce damp and rust — especially in metal sheds.

Best Practices

🌬 Install roof or gable vents
🌬 Avoid blocking airways with heavy shelving
🌬 Leave gap behind shelves for airflow

🧠 9. Storage Organisation Ideas

Make the most of every inch:

• Wall hooks for tools
• Vertical shelving for small pots & bags
• Magnetic strips for metal tools
• Corner racks to save space
• Floor mats to protect base

📆 10. Maintenance Checklist

🗓 Spring & Autumn Checks

• Check roof sealant & felt
• Tighten loose screws
• Treat wood with preservative
• Clean debris from around shed base

🗓 Annually

• Inspect doors, locks, and hinges
• Check for condensation or rot

🧠 Summary – What Matters Most
