The Harriet Davis Trust, one of the UK's only providers of seaside holiday houses designed especially for children with disabilities and their families, has announced its plans for a fourth property in Tenby. The Welsh-based charity, which currently has three houses in the area, was set up 12 years ago by John and Kit Davis from Llangynidr, in memory of their daughter Harriet, who was severely disabled and died in 1992, aged 11. The trust is looking to raise £300,000 for the new property, which will be tailor-designed for children with autism and other learning difficulties and their families. "This will be the first holiday house we've opened especially for children with learning difficulties," said John Davis, 70, from Llangynidr, who set-up the charity with his wife Kit, 66. "Our other three houses were specifically designed for children with physical difficulties, like our daughter Harriet. "She loved going to Tenby on holiday, but as she suffered from a rare metabolic disease and needed a wheelchair, finding suitable accommodation was a problem for us. "The year that Harriet died, we set up the trust in her name. The houses provide all the equipment and security that the child would need - from a hydraulic bed and bath, to hoists and adjustable seats, sinks and tables. "Although we have yet to find a site for the fourth house, it will be designed with children with autism and learning difficulties in mind and this will include additional safety features and extra security within the house." Helping the Harriet Davis Trust to raise funds for the new project is the not-for-profit organisation WHA (Welsh Hospitals & Health Services Association). The organisation, which provides low-cost schemes to help its members meet the cost of everyday healthcare, has already donated £2,500 towards the cost of the house. Chief executive at WHA, Huw Cooke, said: "John and Kit Davis are the most inspirational couple I know. Their hard work and determination has made such a big difference to the lives of children and their families across the UK. "As a parent myself, I think they are wonderful facilities for the whole family. It's an extremely worthy cause and WHA is delighted to be able to pledge its support to the charity once again." John Davis added: "We have a great deal of money to raise in order for this fourth house to become a reality, so we are very grateful to WHA. They have supported us from the beginning, making contributions to each house. We hope that other organisations will follow their example and support our work. "At the moment, the demand we have for our other houses is phenomenal. In fact, they are usually fully booked. We are very keen to get the next house up and running, so no-one misses out on the chance on a holiday." 'Harriet's House', which is located on Castle Square, was the first of the three purpose-designed properties. It was followed by 'Giltar View', which was bought and adapted overlooking the South Beach, and 'The Wheelabout', which was purpose built with an indoor heated swimming pool on the Ridgeway in Penally.
