Twice featured in Denver design magazines, this home is an Observatory Park favorite. A thoughtful blend of both historic and classic architecture, the home was built in 1910. One hundred years later in 2010 the home was completely remodeled including an expansive addition. Located only a block from Observatory Park and gracing a palatial quarter-acre corner lot, the multiple outdoor spaces create a charming estate setting. The home was designed for entertaining with a large covered porch for hosting your friends and family. Just beyond four sets of French doors with transom windows sits a spacious gourmet kitchen with coffered ceiling, double SubZero refrigerator/freezer, 48" Wolf gas range, two Carrara marble islands and book-matched backsplash, custom cabinets and built-in china hutch. Nearby is a unique octagon-shaped room with SubZero wine cooler, bar and storage. Tucked away near the kitchen, the main floor owner's suite features a gas fireplace, built-in bookcases, luxurious 4-piece bath, three large closets and laundry room. French doors overlook the secluded garden and fire pit. Near the kitchen is the back entrance with custom storage and a shower for dogs and garden boots. Up the back stairs is a spacious office with mezzanine but it would also make a perfect playroom or media room. The original part of the home features a gracious front porch and foyer, living room with wood-burning fireplace, a new family room with gas fireplace and a distinctive half-bath. Upstairs are 3 more bedrooms, 2 fully remodeled baths and a charming sunroom. The basement hosts a large exercise room, shop and more storage. This home is a gardener's delight with a raised vegetable garden, blooming perennials, numerous fruit trees and an oversized 3-car garage with more than enough space for storage. A much-loved neighborhood favorite, this home is unlike any other in Observatory Park. Virtual Tour: https://my.matterport.com/show/?m=qobx7Zyszpf; Website: www.3109EWarrenAve.com
