Our Team

Our team is enthusiastic and fun-loving, giving our studio a vibe that is unique Arcadia. Together we inspire each other to create innovative, award-winning designs.

Alex Longley

Alex founded Arcadia in 2011 to establish a landscape firm that is driven to create world-class landscape outcomes. His passion for connecting people with the landscape, and his longstanding industry relationships built on his ability to deliver exceptional projects, have helped Arcadia become one of the leading landscape architecture firms in Sydney. Also key to Arcadia’s success is the way Alex’s belief in nurturing team development has built a talented team within a collaborative workplace environment. Alex has provided the inspiration for a unique studio culture, including Friday BBQs on the deck, the annual ski trip and Arcadia’s famous Christmas parties.

Michael Barnett

Mike became a Principal of Arcadia in 2014 bringing an ability to create authentic and compelling open spaces. Mike excels at challenging the process and driving the team to deliver rigor and detail in their work. This results in project outcomes that exceed client expectations, strengthening Arcadia’s reputation for delivery of quality projects. Mike’s an adventurer at heart – whether you find him snow-boarding, on his motorbike or exploring Sydney’s newest open spaces with his family, you can be sure he’s finding inspiration for his innovative designs.

Nathan Clausen

Nathan’s love of the outdoors has not only led him to a move to Queensland after growing up in NSW, it’s also shaped his passion for designing outdoor places that activate and invigorate spaces for people to enjoy. Nathan is excited by the opportunities for the Arcadia Brisbane studio to help shape public domain in Brisbane, as it becomes an increasingly urban city. He strongly believes access to open space is critically important for optimum physical, mental and spiritual health.

Chris Tidswell

This Adelaide-native always knew he wanted to be a designer. With a passion for designing memorable places, we’re lucky Chris found his way to Sydney, to share his extensive public domain experience with the Arcadia team. While this sports lover may find he’s spending a little less time playing golf, sailing or watching AFL now that he’s a father, we’re sure he’ll have first-hand expertise on what makes a great family-friendly outdoor space.

Lachlan Hunter Hicks

Recently returned to Australia after seven years working at Sasaki, Lachlan brings over 15 years’ extensive architecture, urban design, and landscape management experience to the Arcadia team. Lachlan works to create ‘stages’ that support people and their lives. He thrives on collaboration – working with people to create spaces for people. But when it comes to hobbies, it’s time alone that recharges him, as he takes to Sydney Harbour for a paddle on an OC1 canoe.

Andrew Mason

Andrew is one of the core members of the Arcadia team and our original Kiwi. While not a morning person, this ice hockey player is renowned for his appetite and a natural design flair that seeks elegant design solutions, often inspired by the richness and diversity of the local landscape environs. As the undefeated Arcadia champion, his karaoke skills are a thing of beauty as well…

Katie Leung

Katie’s sunny nature is a great advertisement for the positive endorphins produced by exercise – this keen runner is rarely without a smile! With more than 8 years in landscape architecture, Katie’s expertise is in the areas of planting design, public domain guidelines, tender documentation and aged care and health. She’s also fairly handy with arts and crafts (her lucky daughter!) and can belt out a respectable rendition of ‘Like a Prayer” when the karaoke mike is handed to her. We’re just waiting for the next staff outing so we can convince her to show off her Irish dancing!

Cliff Dean

With a childhood spent between North Brisbane and Fraser Island, Cliff was inspired from a young age to work in a career that allowed him to connect with nature. After time working in Brisbane and Singapore, where he built his expertise in problem solving working across projects in many countries with diverse cultures, we’re so happy Cliff has made the move to Sydney. Not only is he impressing us with his passion for to creating quality landscapes that respond to a site’s social, physical and environmental identity, but he’s also wowed us with fully-dressed backflips into the harbour, mad paper boat-making skills and a side career of doubling colleagues to the light rail on the back of his bike.

James Kidd

James is one of those people that knows stuff. If you’re sitting near him, forget google – James will have the answer to any problem or know the movie quote. He’s a man of many talents – obviously he’s pretty talented at landscape architecture, with a particular talent for creating successful outdoor learning spaces, using his passion for designing meaningful spaces to foster relationships
with nature, architecture and the environment. But he’s also an accomplished cook (he has the best leftovers for lunch!), he’s sporty, he can even run a photo booth or step in as a DJ at your next party.

Mo Khallaff

Our BIM Manager Mo comes to Arcadia from Egypt, via time working in New York, and shares our passion for designing and delivering projects to a high standard. Mo  not only leads Arcadia’s early adoption of BIM, he also lectures in the Architecture and Construction Project Management program at UTS. And he does all this while experiencing the joy of being a new parent…. and the not so joyful side effect of interrupted sleep! Not that you’d ever pick that with his calm personality.

Jonathan Fleri

Mad for the Sydney Swans (footy, beer and pies – what’s not to love?), Jonathan’s also a keen landscape photographer. When it comes to Landscape Architecture, he has a passion for integrating urban design and the natural landscape to help form a relationship between the user and the space. And his talents don’t end there…. Jon’s got some slick moves on the snowboard and the dancefloor, as seen on our last Arcadia Ski Trip!

Daniel Spicer

Seeing what Daniel’s mum has packed him for lunch is one of the high points of our day! And then finding out what he buys himself to eat after he finishes Mum’s lunch for morning tea…. Always entertaining, Daniel’s up for anything, whether it’s jumping off the end of Jones Bay Wharf for a lunch-time swim or trekking through the jungles of Malaysia. His passion for travel has helped shape his organic, non-conventional design style and his ability to translate abstract issues into practical and unique solutions. *Update – Dan has moved out of home and is now fending for himself! But the memories of his Mum’s lunches will live on in his profile forevermore…

Georgia Alexander

When Georgia joined Arcadia from a regional landscape architecture practice, she brought her natural design style and love of gardens to the studio. Her claim to fame is one of the best we’ve heard yet – her grandfather wrote the Slim Dusty hit song “I’d Love to Have a Beer with Duncan.” Georgia’s motto is “do what you love and love what you do.” We hope this is more fitting now she’s a Landscape Architect at Arcadia than when she worked in an abattoir or as a rouseabout in a stinking hot shearing shed!

Alia Khan

While we all aim to design landscapes fit for a prince, Alia has actually designed palace gardens for a prince! If there’s a country she hasn’t lived in – Kenya, Austria, England, Bahrain, Australia – this travel enthusiast has probably been there. With energy to burn, outside of work you can find Alia at the beach, cycling, skiing or doing krav maga. She also likes to get in touch with her creative side with painting, sketching, crochet and cooking. If you can find something Alia can’t do, please get in touch for your reward.


Valerie Ostermann

With Valerie joining us, we have a new contender for best ‘Claim to Fame’. Valerie is the former National Fencing Champion of Germany and we are equal parts impressed and terrified by her super ninja skills! This wannabe sheep farmer is also a certified massage therapist, so it’s fair to say she has magic in her hands. Luckily for us, Val is equally talented as a Landscape Architect!

Ryan Morton

With childhood aspirations to be a Top Gun pilot, Ryan has actually become our resident Forrest Gump, with seven half marathons and one marathon under his belt. Ryan’s route to Arcadia, is a bit of a marathon itself – a childhood on a pig farm in New Zealand, university in Canada and time as a landscape architect in Edinburgh. Now he’s landed in Sydney to wow us with his design talent and torture us with his obsession with William Hung Christmas Carols…

Stacey Edwards

Stacey – she’s All Blacks and not Wallabies. She’s Halloween and never Christmas. She’s books over TV and she’s coffee, not tea. And best of all she’s “Hell yes, I’ll give it a go” and we love her for it! Since joining us as a Landscape Architect, Stacey’s innovative ideas around WSUD infrastructures, as well as her love of trees and fauna, have helped to create her unique landscape design style which are an asset to any project.

Sophie Randall

Sophie is dedicated to getting the job done – even if it means climbing a tree to get to a dumped share bike for Business Clean Up Australia Day. Sophie’s happy place is anywhere with a surfboard and her love of the outdoors and coastal environments has a big influence on her designs. Look out when she gets control of the office playlist – it’ll be Spice Girls all day!

Chang Liu

Coming from Xinxiang, a small city in China, Chang has brought a simple, fresh and contemporary design approach to Arcadia, combining her modern Asian influences with an enthusiasm to embrace and experience the outdoor lifestyle of Sydney. Her favourite outdoor space is a table tennis court – but while she plays to relax, she’s happiest when she’s winning. That’s the competitive spirit that makes Chang perfect for Arcadia!

Kaylie Salvatori

We’re thrilled Kaylie has joined Arcadia, after study at UNSW where she was the recipient of the Arcadia Landscape Architecture Scholarship for Indigenous Students. Despite strong family ties to the Rabbitohs, Kaylie is not sporty at all – unless you count her stint as a horse riding instructor. Painting, drawing and sculpture are her passions and Kaylie’s love of art, combined with her love of nature, have led her to a career in landscape architecture. We’re excited about the opportunities ahead, weaving Kaylie’s passion and knowledge of Indigenous culture and native foods into our designs.

Pip Meachin

Pip joined Arcadia to help spread the word about the amazing work the team is doing. The studio is her happy place – instead of spending the day trying to whip her family, dog and messy house into shape, she gets to work on content for our website, social media, newsletters, awards and media. With our incredible view and fun team, what’s not to love about coming to work?

Julia Delaney

Sadly our studio manager can’t be with us every day, but it’s obvious the days when Julia is in the studio. Things work, timesheets get done and her positive, motivational energy is felt throughout Arcadia. And when this organisational genius isn’t here, she makes sure there is a bowl of sweet treats to remember her by. It’s a shame she can’t ditch her kids and look after us every day!

Crystal Dunn

Did you ever get told that if you find something you love, buy more than one? That’s what we did with our office managers – Crystal is the ‘yin’ to Julia’s ‘yang’ and together they make sure everything at Arcadia works to its full potential. When Crystal isn’t in the studio, she’s using her exceptional teaching skills to shape the minds of Sydney’s primary school kids or she’s out and about enjoying the beautiful outdoors with some hiking or beach time.

Saskia Ruting

Our graphic design genius, Saskia, hails from the northern beaches – Home & Away fans may even have seen her childhood home in the background of some scenes. If she’s not at the beach, weekends will find her hiking, camping or making ceramics. It’s not surprising Saskia is able to respond with detailed, beautiful work in any situation. One of her first jobs was selling balloons at a Wiggles concert. Anyone able to deal with savage parents when the Dorothy balloons run out, is able to handle anything!
