Calls are being made for builders, trades people and manufacturers to lend a hand with the construction of the first ever Irish National Respite Centre for Children with rare diseases and their families.

The site in Tralee in Co. Kerry will be formally launched later. It is hoped the facility can be built within the next 2 years.

It is the brainchild of Tony and Mary Heffernan who tragically lost their 5-year-old daughter Saoirse to Batten's Disease in 2011. Their 4-year-old son Liam has also been diagnosed with the same condition.

Over 200,000 children in Ireland are effected by genetic and rare diseases. If you would like to donate to this cause or help build the facility you can click here for more information.

Phase one will see an initial 10 specially-designed units constructed to provide a week of much needed respite for 520 families each year. In the longer term it will grow to 30 units with a number of satellite Lodges around the country. It is hoped over 1,600 families a year will benefit.

Founder Tony Heffernan explains the type of services the centre will provide to sick kids and their families.
