🧱 Base Requirements

A solid foundation for your perfect garden building

A strong, reliable base is essential for any long-lasting structure — whether it’s your dream shed, summerhouse, or garden room. At Ashdown Garden Buildings, we understand the importance of a base that’s level, stable, and built to last.

If you need help preparing the right base for your building, our team is here to assist. We offer tailored advice and can provide a personalised quote to suit your needs.

📞 Call our Angmering branch on 01903 491 874

📞 Or contact our Washington branch on 01903 491 492

We’re happy to guide you every step of the way.

💧 Guttering Options

Gutters – Protect Your Building and Collect Rainwater

Installing guttering on your shed is a smart addition that helps extend the life of your building. It prevents rainwater from running down the sides, minimises the risk of damp and rot, and stops water from pooling around the base.

Guttering also gives you the opportunity to collect rainwater in a water butt — perfect for eco-friendly garden watering.

🌲 Pressure Treated Bearers

Pressure-Treated Bearers – Extra Protection for Your Building

Pressure-treated bearers provide vital support and protection for the base of your building. By raising the floor slightly off the ground, they help reduce the risk of moisture damage, rot, and rising damp — significantly extending the lifespan of your building.

Suitable for all of our buildings, they also improve airflow beneath the structure to keep your building dry and well-ventilated.

Interested in adding bearers to your order? Get in touch today! We’ll be happy to provide advice or a quote tailored to your building.
