Sand Martin Bank

A completely new design, this is a sand martin bank that we constructed for the Abberton Reservoir site that is managed by Essex Wildlife Trust (where we have already built five bird hides, a children’s visitor centre, and an outdoor play area). As you can see, this particularly structure is ‘conveniently’ located on an island, meaning that after we had built the structure in our Norfolk workshop, we had to make a temporary water crossing that allowed us to reverse our trailer onto the island and unload the sand martin bank in its final position.


The Design and Construction


We constructed the sand martin bank with an insulated, sedum roof and purpose built nesting holes, each featuring a soft, mortar entrance. Each hole is sculpted to emulate real holes in a real bank, with clay pipes down to a sand / soil nest chamber. Each nest has an accessible box for monitoring of the nest, and the entire structure is insulated to protect it from the heat of the sun. Visual intrusion into the landscape is minimised with soft profiles and a sedum roof that is held in place with wire mesh through which it will grow. To help the future sand martin residents flourish, the entire structure is vermin proof with a mesh floor and anti-climb baffles.


Your Project


Although this is the first time we have been a sand martin bank, we believe that the project was a resounding success and we look forward to the first residents moving in when the weather warms up. This project is just one small example of how we can custom build any timber structure that you might require, so use it as inspiration for your own project. Please take a look at our other custom made timber structures and don’t hesitate to get in touch with us if you would like to discuss your own project. We would love to help you through the design process.
