The flutterBy Treehouse was HDR's entry into the Dallas Arboretum Ultimate Treehouse Competition. The design was one of 12 selected from more than 60 entries to be featured in the temporary exhibit. flutterBy was an interactive experience that intertwined nature and design. The wings of the treehouse were interwoven among the branches of the tree, while the body stretched out as a ramp into the landscape allowing the experience to be accessible by all. Tube steel, fabric, and cable structure formed the forty foot wing span creating delicate veining reminiscent of a butterfly's wing. The connection with the site was enhanced by a butterfly garden around the base, mirroring the contours of the wings above. The vibrant colors and fragrances in the garden attracted butterflies to the area, making flutterBy a standout project in the competition.
