Zoo and animal enclosures

Alpha RAT offers installation, inspection and maintenance of animal structures, enclosures and aviaries. With an office in Bristol we operate nationwide.

Over the years we have carried out multiple installation and maintenance projects across the UK. From small monkey enclosures, through wader birds aviary to a grand-scale tiger and leopard enclosures, we have been involved in the most iconic Zoo structures in the UK. Our extensive knowledge and unmatched high-level access capabilities put us in front of other specialist construction companies.

We Work With a Wide range of Materials:

  • Polyethene and polypropylene nets
  • Stainless steel mesh
  • Galvanized or stainless steel welded mesh
  • Steel support structures
  • Timber support structures


When designing the new animal habitat, the priority is always the welfare of the animals. That’s why we start by consulting animal specialists, behaviourists, biologists and zookeepers to establish the necessary requirements and constraints for the enclosure design. We work with designers and structural engineers experienced in designing Zoo structures, to create the most suitable design for a given purpose


Installation is where our vast experience comes to life. Zoo gardens are often very demanding environments for construction companies. Most of the time, work takes place when the Zoo garden is operational, with the ground and surrounding conditions far from ideal. We use a variety of access and installation methods to carry out the installation in the most efficient way, with minimum disturbance to the busy life of the Zoo garden.


Like all other structures, animal enclosures need periodical maintenance. Most of the time that’s done by the Zoo staff, but sometimes specialists are needed to carry out maintenance or repair works beyond the capabilities of the Zoo maintenance team. Our engineers regularly carry out maintenance work to the Zoo structures, usually at height or where access is a problem, for example above water.


Alpha RAT Ltd has been involved in multiple installation and maintenance projects of various bird aviaries. From small net aviaries at Birdworld, through a mid-size walk-through aviary in Marwell Zoo to the seafront coastal zoo & aquarium in Torquay and Brookside aviary in Paignton Zoo. Our access methods prove invaluable when installation or repair work requires work at heights. All our technicians are fully qualified and trained in rope access (industrial abseiling).


Animal enclosures require attention to detail. At the end of the day, our goal is for those animals to remain safe inside the enclosure. We build and maintain a variety of animal enclosures and we work with multiple materials like PE nets, stainless steel mesh or welded mesh. We can install structures based on steel or timber frames. Our technicians have been involved in multiple projects within the UK including Bristol Zoo, Paignton Zoo, Marwell Zoo, Birdworld, Living coasts, Chessington and Twycross Zoo.

Walk through enclosures

Walk through enclosures give a fantastic opportunity for the public to experience animals in an environment created to mimic their natural habitat. Being up close with the animals, within the same enclosure gives an invaluable experience for the visitors. We like those types of structures. Our favourite one is still Living Coasts in Torquay.


Each Zoo or wildlife project needs temporary holding pens. They are usually out of public view and need to be simple and functional. A lightweight, tubular steel structure with metal or PE mesh is usually the most effective solution. We can build those as well.
