🧠 Key Features to Look For in Wet Sites

🪵 Material Choice Matters

• Composite or treated timber: Damp-resistant
• Untreated timber: Avoid it; rot risk is high
• Metal or strong PVC fascias: Resist decay

---

💧 Base Choice Is Critical

The structure above ground will only perform as well as its base:

🛠 Screw Pile Bases

• Best for waterlogged or soft soil
• Elevates the office above damp ground
• Allows airflow beneath the building

🧱 Concrete Slab with Slope & Drainage

• Solid and stable
• Must be sloped slightly to shed water away from the office
• Ideal for heavier, insulated offices

🪵 Raised Timber Bearer Base

• Cheaper than concrete
• Air circulates under office
• Works well with composite builds

Base Tip: Avoid laying slabs directly on bare soil — water gets under them and causes damp.

🌧️ Moisture Prevention Strategies

✨ French Drains & Perimeter Channels
Direct water away from the office footprint

🚰 Gutters & Downpipes
Collect rainwater and divert it to storm drains or soakaways

🔨 Ventilation Vents Under Floor
Promote airflow under the office to reduce rot risk

📏 Site Slope Adjustment
Ensure the office base sits slightly higher than the surrounding soil

---

☀️ Design Tips for Weather-Proof Comfort

✔ Choose double-glazed windows with good seals
✔ Ensure door thresholds are raised or weather-strip sealed
✔ Add internal insulation (walls, roof, floor) to reduce condensation
✔ Include ventilation vents or window vents for airflow
