The Eco-friendly RoofBLOCK Bird Box provides a better solution.

We all have a responsibility to protect birds and the environment. Bird populations reflect the health of the planet on which our future depends and are a valued part of our natural world, therefore we should all make an effort to accommodate them.

A RoofBLOCK bird box makes an ideal home for birds as unlike timber the thick concrete walls keep the bird box at a more uniform temperature thus avoiding overheating and killing the chicks. 

RoofBLOCK Ltd have adapted their eco-friendly masonry block with a large circular opening on the front face for cleaning out purposes, which can also be reduced to attact different bird species. 

The masonry bird box with a solid end is built alongside another similar solid end RoofBLOCK but without the hole so as to contain the birds within a single block. Confined within the hollow portion on the outside of the exterior wall, the birds are unable to enter the building and cannot disturb the homeowners.

Built seamlessly into the masonry roof overhang, the RoofBLOCK bird box provides not only a visually neater solution than at present with bird boxes tacked on the side of a wall but it also forms a totally maintenance-free alternative to wooden or plastic fascias and soffits that will now last for the whole life of a building.

Ideal location

Generally the RoofBLOCK bird box is protected from the elements by the roof overhang and therefore the direction it faces is not too important. However, it is best to avoid locating boxes facing south west as this is the prevailing wind direction and could cause problems with summer storms, heavy rain and cold winds.

As nest places can become very hot during the summer breeding season (April to August), so hot that the chicks may expire, best success is on the sides of the building out of strong sunlight. Unless there are trees or buildings which shade the box during the day, face the box between north and east, thus avoiding strong sunlight and the wettest winds. 

Other considerations

Make sure that the birds have a clear flight path to the nest without any clutter directly in front of the entrance. 

House sparrows and starlings will readily use nestboxes placed high up under the eaves. Since these birds nest in loose colonies, two or three can be sited spaced out on the same side of the house. Keep these away from areas where house martins normally nest. 


A less labour-intensive way to make a nest is to use a hole that already exists. Many birds, including tits and owls, take advantage of natural holes in trees as a ready-made place to bring up their young. 

Others, like starlings and house sparrows, have learnt to take advantage of holes in roofs to make their nests. Once they have chosen their nest site, it still needs lining, but it requires much less careful craftsmanship. It’s a quick job for sparrows to stuff their hole with grass, which looks rather untidy, but does the trick.

All this nest building takes time and energy from birds. The less effort that they have to put into collecting nest material, the quicker they can get settled into egg-laying and rearing a brood. 

Here are some tips on things you can do to help birds nesting near you:

  • Leave out natural fibres and pieces of plant materials for birds to collect. Place these in a hanging plant basket or nearby bush to make it easier for the birds to collect nesting material quickly. 
  • House sparrows prefer to collect nest material from within a few metres of their nest. They use straw, grasses, fur, hair and other natural materials to make their nests, so provide some when you can. 
  • Starlings use fresh cut green leaves from spring pruning of shrubs. They may also use moss raked from your lawn, fur, hair and wool. 
  • House martins, song thrushes and blackbirds use mud in the construction of their nests. A small, wet, muddy patch in your garden, such as a muddy puddle or edge of a pond, may make it easier for them to build a nest, particularly if it has been dry and there are no other nearby sources.     

Many species have halved in number over the last 25 years, including some of the UK’s best known birds.

Climate change is the biggest issue facing wildlife and humanity this century reflecting the growing pressure that people exert on the planet, but if we do not tackle them intelligently, people will suffer as much as the natural environment.

It's time to put wildlife back into our environment and our lives.
