Modern design collector Mark McDonald is looking to sell his 1960s Hudson Valley retreat, which he gave a modern makeover, for $3.35 million.\u00a0<\/p>\n

The 40-acre estate in Hillsdale, New York, is anchored by a three-bedroom house designed by architect George B. Post, who is better known for designing neoclassical civic buildings like the New York Stock Exchange.\u00a0<\/p>\n

The 1966 home<\/a> sits on a rocky slab near a spring-fed pond and is surrounded by wooded hills, walking trails and ridges with some of the highest elevations in the region, commanding views of the Taconic Mountains to the southeast and the Helderberg Mountains to the southwest.\u00a0<\/p>\n

When McDonald, a gallerist and collector of modern furniture and design, purchased the estate in 2005 from the original owners, the 1960s home badly needed a refresh, he said. Though it was solidly built because of its commercial architect, the finishes and layout had grown dated.<\/p>\n

\u201cIt was dark, even though there are so many windows; it was just depressing,\u201d McDonald said.<\/p>\n

So McDonald recast the single-story home with a minimalist sensibility inspired by Frank Lloyd Wright and a passion for midcentury architecture. He raised the ceilings to allow in more light, opened up the kitchen to facilitate flow and extended a hand-laid interior rock wall made of found river rocks.\u00a0<\/p>\n

McDonald clad the exterior in horizontal wood siding that accentuated the \u201clong, low, beautiful\u201d lines of the house, he said. While on the interior, he laid down walnut flooring and installed layered poplar wood on the raised ceiling.\u00a0<\/p>\n

\u201cThis area is not overwhelmingly full of midcentury architecture, so to find one thoughtfully modernized and restored by their owners is a really unique opportunity,\u201d said listing agent Marina Schindler of Compass, who posted the house Thursday.<\/p>\n

The property also features a guest suite, a custom-built tractor shed, and an artist\u2019s studio with a deck and indoor sauna that faces amazing views, Schindler said. \u201cYou can almost look all the way up to Albany.\u201d There are also manicured gardens, a swimming pond with a dock and diving board, and plenty of areas to sit, lounge and meditate.\u00a0\u00a0<\/p>\n

The residential portion of the property, spanning about 4 acres, is fenced to keep out the deer and allow for the gardens, tended by McDonald himself, who also cut the walking trails through the woods, expanding on an existing logging trail. \u201cIt goes up the hill behind the house to the highest point and loops back around behind the pond,\u201d he said. \u201cI think it\u2019s the greatest thing about the property.\u201d<\/p>\n

The property was originally designed as a retreat for the wealthy Williams family, owners of the I.T. Williams Company, founded in 1838 as an importer of exotic hardwoods, first from India and later from South America, after the invention of flat-bottomed boats allowed travel through the Amazon, according to McDonald.\u00a0<\/p>\n

Before finding this property, McDonald had worked on a handful of other small construction projects, including setting up a gallery in New York City\u2019s Meatpacking District back in the 1990s, rehabbing another Hudson Valley home, and restoring a Hudson retail store that he used as a shop. He also recently collaborated with Steven Holl Architects on a live-work property on an infill lot in Hudson, New York, called the \u201cL\u201d house for its shape.\u00a0<\/p>\n

\u201cHe\u2019s done projects like this before, bringing a house to a really beautiful place with his aesthetic and his appreciation for history and architecture and interiors,\u201d Schendler said.<\/p>\n

But this one stands out. \u201cThis project was the most extensive,\u201d McDonald said. \u201cIt took the longest, and it\u2019s the most satisfying thing I\u2019ve ever done.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Modern design collector Mark McDonald is looking to sell his 1960s Hudson Valley retreat, which he gave a…\n","protected":false},"author":3,"featured_media":686662,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[32],"tags":[88035,2513,1037,648,11321,1032,257859,64,233108,9886,233114,220532,220780,220541,220783,220533,220542,1033,288128,171,190234,57,220527,220536,288125,288129,258675,258686,17050,587,47274,3234,190263,4329,76954,251354,258684,288126,10204,5677,220530,220539,5660,288127,1650,67,132,68,220543],"class_list":["post-686661","post","type-post","status-publish","format-standard","has-post-thumbnail","category-arts-and-design","tag-architects","tag-architecture","tag-art","tag-arts","tag-arts-entertainment","tag-arts-and-design","tag-building-construction","tag-business","tag-business-consumer-services","tag-construction","tag-consumer-services","tag-content-type-content-type-article","tag-content-type-content-type-gallery","tag-content-type_content-type-article","tag-content-type_content-type-gallery","tag-credited-by-mansion-global","tag-credited_by_mansion_global","tag-design","tag-design-services","tag-entertainment","tag-gcapi","tag-general-news","tag-integration-apple-news","tag-integration_apple-news","tag-lifestyle-lifestyle-country-living","tag-lifestyle_lifestyle-country-living","tag-location-market-new-york","tag-location_market-new-york","tag-new-york-state","tag-north-america","tag-northeast-u-s","tag-political","tag-political-general-news","tag-real-estate","tag-real-estate-services","tag-real-estate-services-transactions","tag-real-estate-construction","tag-residential-building-construction","tag-residential-real-estate","tag-services","tag-subject-subject-new-listings","tag-subject_subject-new-listings","tag-synd","tag-technical-services","tag-transactions","tag-united-states","tag-unitedstates","tag-us","tag-wsj-pro-mansion-global"],"share_on_mastodon":{"url":"","error":"Validation failed: Text character limit of 500 exceeded"},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/686661","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/comments?post=686661"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/686661\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media\/686662"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media?parent=686661"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/categories?post=686661"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/tags?post=686661"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
