Huge thanks to the architect Malachi Connolly for the shout-out on this article on @remodelista ! Very proud of his work, and the skilled work of our guys in the wood shop for making this beautiful screen door! Posted @withrepost • @remodelista Remodelista’s Editor in Chief, Julie Carlson ( @remodelistajc ), recently decided to renovate the small guest cottage in the backyard of her home on Cape Cod. Since inheriting the property from her mother in 2004, the small structure had remained untouched and had become almost uninhabitable. She enlisted her friend Malachi Connolly, a New York and Cape Cod-based architect and preservationist, to come up with a plan. “I love the intimacy and efficiency of small spaces,” Malachi says. “It was nice to work with the simple shed shape, which organically provided a sitting room downstairs and a sleeping loft upstairs. This separation of elements lent a kind of purity to the contemplation of how to craft the spaces.” Tell us what you think in the comments! Photography and styling by @justine.hand .
