About Us

In 2001, aged 24, horticulturist Donegan began designing under his own name and swiftly won a host of awards for 17th & 18th century gardens designed & show gardens at national competition.

From 2019 to 2022, The Royal Horticultural Society (RHS) silver medallist assumed the role of series garden designer for Ireland’s most watched TV show, RTE’s DIY SOS The Big Build.

Selected to represent Ireland to design & realise the WW1 Centenary Peace Garden at Château de Péronne in 2018, he returned and designed a 2nd inaugurated garden at the 13th Century castle known also as the Historial de la Grande Guerre, home to Europe’s largest war museum. 

2023 Donegan became the first Irish garden designer to win Gold Medal at Melbourne International Flower and Garden Show, the Southern Hemisphere’s largest and most prestigious flower show. 

Peter Donegan MSGD is a registered member of The Society of Garden Designers (UK).
