Set just below the iconic Flatirons in the storied Chautauqua neighborhood, this 2008 residence by celebrated Boulder architect Harvey Hine, remodeled throughout in 2023, unites a restored 1914 stone cottage with a striking nautilus-shaped contemporary addition. A soaring 23-foot entry with a dramatic cantilevered staircase introduces an expansive open layout where historic character and modern design converge, finished with the finest custom details throughout. Gently curved walls, vaulted ceilings, and a kitchen that opens to a private deck create seamless indoor-outdoor flow, while a main-level primary suite offers two walk-in closets and a private office. Thoughtful landscaping ensures privacy, yet Chautauqua Park trails are just two blocks away and downtown Boulder dining is only minutes from the door. Property and opportunity details provided by seller or others; buyer to verify.
Situada justo al pie de los emblemáticos Flatirons, en el histórico barrio de Chautauqua, esta residencia de 2008, obra del célebre arquitecto de Boulder Harvey Hine y totalmente reformada en 2023, combina una casa de campo de piedra de 1914 restaurada con una llamativa ampliación contemporánea con forma de nautilo. Una imponente entrada de 23 pies de altura, con una espectacular escalera en voladizo, da paso a una amplia distribución diáfana en la que convergen el carácter histórico y el diseño moderno, rematada con los mejores detalles personalizados en todas sus estancias. Las paredes suavemente curvadas, los techos abovedados y una cocina que se abre a una terraza privada crean una transición fluida entre el interior y el exterior, mientras que la suite principal, situada en la planta baja, cuenta con dos vestidores y un despacho privado. El cuidado diseño del jardín garantiza la privacidad, aunque los senderos del parque Chautauqua están a solo dos manzanas y los restaurantes del centro de Boulder se encuentran a tan solo unos minutos de la puerta. Los detalles de la propiedad y de la oportunidad han sido facilitados por el vendedor u otras personas; el comprador deberá verificarlos.
Située juste au pied des emblématiques Flatirons, dans le quartier historique de Chautauqua, cette résidence construite en 2008 par le célèbre architecte de Boulder Harvey Hine, entièrement rénovée en 2023, allie un cottage en pierre de 1914 restauré à une extension contemporaine saisissante en forme de nautile. Une entrée imposante de 23 pieds de haut, agrémentée d’un escalier en porte-à-faux spectaculaire, donne accès à un vaste espace ouvert où le caractère historique et le design moderne se marient harmonieusement, le tout rehaussé par les plus beaux détails sur mesure. Des murs légèrement incurvés, des plafonds voûtés et une cuisine s’ouvrant sur une terrasse privée créent une transition harmonieuse entre l’intérieur et l’extérieur, tandis que la suite parentale, située au rez-de-chaussée, dispose de deux dressings et d’un bureau privé. Un aménagement paysager soigné garantit l’intimité, mais les sentiers du parc de Chautauqua ne sont qu’à deux pâtés de maisons et les restaurants du centre-ville de Boulder ne sont qu’à quelques minutes de la porte. Les détails relatifs au bien et à l’opportunité sont fournis par le vendeur ou des tiers ; il appartient à l’acheteur de les vérifier.
Situata proprio ai piedi delle iconiche Flatirons, nel storico quartiere di Chautauqua, questa residenza del 2008, opera del celebre architetto di Boulder Harvey Hine e completamente ristrutturata nel 2023, unisce un cottage in pietra del 1914 restaurato a una suggestiva aggiunta contemporanea a forma di nautilus. Un imponente ingresso alto 23 piedi, con una spettacolare scala a sbalzo, introduce un ampio spazio a pianta aperta in cui il carattere storico e il design moderno si fondono, rifinito in ogni dettaglio con i migliori elementi su misura. Pareti delicatamente curve, soffitti a volta e una cucina che si apre su una terrazza privata creano un flusso continuo tra interno ed esterno, mentre la suite padronale al piano terra offre due cabine armadio e uno studio privato. Un'attenta progettazione del paesaggio garantisce la privacy, ma i sentieri del Chautauqua Park sono a soli due isolati di distanza e i ristoranti del centro di Boulder sono a pochi minuti da casa. I dettagli relativi all’immobile e all’opportunità sono forniti dal venditore o da terzi; l’acquirente è tenuto a verificarli.

At the edge of the Rocky Mountain foothills, Boulder pairs world-class outdoor recreation with a sophisticated cultural and culinary scene. The neighborhood's namesake, the Colorado Chautauqua, is one of only two National Historic Landmarks in Colorado that offer public lodging. It hosts cultural programming throughout the year, along with a full-service Dining Hall and a General Store, and its historic auditorium draws acclaimed performers each summer. From Chautauqua Park, trails climb into the Flatirons for hiking, trail running, and technical rock climbing. The Boulder Creek Path and nearby Eldorado Canyon State Park offer cycling, fly fishing, and more climbing. Downtown, the Pearl Street Mall is lined with boutiques, galleries, and cafés. Among its restaurants is Frasca Food and Wine, a 2025 James Beard Award winner for Outstanding Restaurant that holds a Michelin star, with a menu that explores the Friuli-Venezia Giulia region of Italy. High above town, the Flagstaff House has served fine dining for more than 50 years, with views that rival its cuisine. Oak at Fourteenth and Jax Fish House & Oyster Bar round out the scene. The Boulder Theater, the Fox Theatre, and University of Colorado athletics at Folsom Field provide year-round entertainment.
