Jonathan Clark Architects (JCA) has taken the wraps off the new £4.8 million Mary Tealby Kennels at the Battersea Dogs and Cats Home in south London
The 2,000m² structure, which was named after the founder of the famous animal charity, houses 56 ‘new intake kennels’ in a 165m-long block.
The ground conditions of the site - which is across the railway tracks from Battersea Power Station - meant the building required 197 piled foundations averaging 16m in depth. Above ground, loadbearing concrete walls support a precast concrete roof.
The exterior facades are faced with a Sto render and the colour schemes are used as a wayfinding aid both inside and out.
‘The graphic composition of the coloured sections below the stone-coloured upper band has been influenced by the continuous movement of dogs up and down the length of the kennels,’ said practice founder Clark.
The long, linear arrangement of the kennels prevents the dogs from seeing each other and raising stress levels. Each kennel faces north-east to minimise solar gain. This tactic, coupled with the blockwork’s thermal mass, reduces the need for mechanical cooling. The kennels’ roof is covered with a wildflower meadow to further improve thermal efficiency.
The architect has also completed a new intake centre for recieving stray and unwanted dogs. The entrance fascia and ‘blade’ structure are clad in Trespa panels.
‘It was important that the kennels did not actually look like kennels in order to gain approval from the future stakeholders adjacent to the site, who were fully consulted during the design and planning phases.
‘A combination of orientation, solar control, good insulation, double glazing, high thermal mass, underfloor heating and a BMS-controlled natural ventilation system has been used to meet the optimum temperature and air change requirements for dogs, particularly the more vulnerable. Seasonal flexibility is achieved through use of glazed shutters to each run, which can be opened up to the outside air in summer but closed to create a thermal buffer zone in winter.
‘The building is designed to high environmental standards, with a 25 per cent reduction in energy use compared to a building meeting current Building Regulations. The building achieves BREEAM ‘Very Good’.
‘The energy efficiency is achieved through good insulation, with a high thermal mass to even out diurnal temperature changes and avoid the need for mechanical cooling systems. Renewable technology is incorporated with a 142m-long array of photovoltaic panels forming a canopy above the kennel walkway. This provides energy to the air source heat pumps, which economically generate hot water for the underfloor heating system. The latter can also be run in a reverse cycle to keep the floors cool on hot summer days.’
