I have only positive things to say about Dirk’s work. He completely redid our backyard, and it’s awesome! It’s a small yard, which can actually make it harder to design effectively since every square foot has to be properly designed. He did a great job! Our backyard seems a lot bigger now, even though we added a small artist studio back there. Not only does Dirk know everything about native plants and where they should go for proper sun and watering, but he also has a great sense of space, and undertands about rocks, walls, water fixtures and structural issues. In addition he has strong knowledge of construction and engineering, much more than your typical landscape architect, so his designs properly factor everything in for a great results. You can’t go wrong hiring Dirk for small yards or huge estates. He has much experience with both. And on top of everything he is honest, friendly and a pleasure to work with. We love our new backyard thanks to Dirk.
