Hi I’m Helen Mulligan and I founded Tilia Garden Design in 2015. Based in High Barnet, North London I decided to retrain as a garden designer after working for many years in marketing for a large publishing and events company. Previously trained in theatre and dance, I’m now happy to be returning to a more creative role and connecting with nature.
​
I believe in creating beautiful outdoor spaces that are in harmony with nature and as the lead designer, I’m passionate about sustainability and caring for the environment. My team takes pride in using organic gardening techniques and avoiding harsh chemicals. And you can trust us, we won’t use fake grass in any of our garden designs!

I also offer a range of garden maintenance services to help you create and maintain a beautiful garden. Whether you need regular garden maintenance, or a one-off garden clearance, we’ve got you covered. Need some in-depth knowledge? Our team of experts are also trained in pruning, training climbers and topiary. We can also provide a plant sourcing and planting service.
