Owners Lorna and Brendan Maye bought the business in 2011 and have cleared and developed the site and added a catering offer, operated initially from a shipping container.
Brendan Maye said: "We couldn't believe it when we got the phone call to tell us that we'd won the prize, and to be able to tune into and trust the years of down-to-earth advice that runs across the whole team at Horti Catering. This level of expertise will help us to boost the future growth of the business. We hope to be selling our first panini and lavender cakes from the new unit in the next few weeks - it's all very exciting. "
HortiCatering managing director Amanda McGreavy oversaw the project: "Being able to reinvest profits back into the coffee shop as footfall increases is vital. We work closely with our clients with the future in mind so they can expand easily as and when the business allows. "
HortiCatering will be at Glee again on 14-16 September 2014.
