A raised bed can be achieved using a mixture of pitched walling and Bradstone walling products. Leaving openings in the wall will allow for areas to be filled with air bricks or Bradstone edging to create habitat hotels. After filling your new raised bed with soil and scented plants to attract pollinators you can then add the bits to your hotel, for this you can use cut bamboo poles, drilled logs and dry leaves. Pine cones, twigs and old pieces of tiles can also be used. If you have more space a wider deep raised bad can be made as a rectangle and planted up with a variety of vegetables alongside nectar rich annuals.
