Bee Blocks


Bee Blocks

Our ‘Bee Blocks’ are designed to provide a manmade nesting site to support the declining solitary bee population. We are facing a severe decline in bee species due to disease, an increase in chemical use and habitat loss.

Bee blocks can be used either as integral parts of building or can be positioned as free standing bee nests in the garden. They offer the dual function of being a construction material that also promotes biodiversity. We designed the bee blocks to sit alongside current green systems like Solar panels, rainwater harvesting and Sedum roofs.

How they work

Each Bee block contains cavities for solitary bees to lay their eggs. Each cavity is moulded part way into the block ensuring bees cannot enter the building. Bees lay their eggs inside the holes and seal the entrance with mud or chewed up vegetation. The offspring emerge the following Spring and begin the cycle again.

What is new about it

We have taken a mainstream construction material as a starting point and reworked it to become a home for nesting bees. Whether used as a stand alone product in your garden or situated in the wall of a new build, garden or garage, bee blocks provide additional habitat for bees in spaces where they may otherwise have been forced out.


Our Bee blocks are cast from concrete in small batches in our Cornish studio, and allowed to dry naturally.


The Bee block should be positioned in a warm sunny spot, preferably a south facing wall, with no vegetation in front of the holes. Ideally they should be positioned at a height of around 1.5m. The more bee blocks you use the more bees can nest so the quantity you choose to use is driven by your design aesthetic.

About solitary bees

Solitary bees are non aggressive and as such are very pet and child friendly. Solitary bees will not sting you unless you squash them, and even then their stings are not painful. They are a vital part of your local bio-diversity and should be encouraged and cherished, particularly by gardeners as they pollinate fruit crops. Bee populations are in decline and introducing measures now to reverse this is absolutely essential.

Our vision

We want to see our Bee bricks and Bee blocks being used in building projects around the country. We have created a simple, beautiful product that can, potentially, be included in every new building project, creating vital habitat for an under threat species. We are passionate about providing habitats for wildlife species and the Bee brick is our starting point.


Our Small Bee block is 65mm x 70mm x 105mm

Our Large Bee block is 105mm x 105mm x 105mm

The Bee Brick is currently undergoing a series of tests at Plymouth University and we will update our site once we receive results, please sign up to receive our emails if you would like more information when we have these results (sign up here). No regulation certification exists for our Bee Brick and as such it can be used in construction but must be classed as a non-load bearing material. Please contact us for details of our coloured bricks and colour matching service.
