Exclusive Mountain Retreat in Monchique – Award-Winning Architecture and Total Privacy Costaneira da Fóia · Private Valley · Monchique There are houses you buy. There are works of art you collect. This property belongs firmly to the second category. Designed by the prestigious British architect Adam Richards and nestled in Costaneira da Fóia, this estate does not seek attention. It commands its own valley with the quiet confidence of something that has nothing to prove. Mature oak and eucalyptus groves frame the property, while a mountain stream meanders unhurriedly through it. The architecture emerges from the landscape as if it had always been there. The main house unfolds across three floors, connected by a sequence of spaces that culminates in a double-height gallery. The spacious living room, bathed in natural light, flows seamlessly into the kitchen and onto the terraces, creating an atmosphere that few Algarvian interiors can match. The three bedrooms—each en-suite with bathrooms crafted from premium materials—fulfill the exact same promise: comfort without artifice. Outside, terraces and porches featuring flamed granite and traditional Portuguese cobblestone (calçada portuguesa) create a sequence of spaces that alternate between intimacy and contemplation. Here, you will find areas for alfresco dining, a private pool, and a valley that unfolds in absolute silence. Separated from the main residence, the guesthouse is a complete and independent sanctuary in its own right, featuring its own living room, kitchen, and bedrooms. It is ideal for family, close friends, or high-end rental use. Built in 2008 on the footprint of a ruined farmhouse and updated in 2025, the property marries traditional stonework mastery with contemporary engineering: double-layer walls with high-density insulation, aluminum window frames with Gris Patine thermal break, and ash wood cabinetry. A finalist in the Grand Designs Awards (International category), the project was subsequently published in 21st Century Houses: 150 of the World's Best (Images Publishing) and Build-On: Converted Architecture & Transformed Buildings (Gestalten, 2009). Self-sufficient in water supply and sanitation, it was designed for those who value independence as much as design. Main House: Floor 1: Two en-suite bedrooms with outdoor access and an elevator. Floor 2: Living room with an open-plan kitchen and mountain views, the master suite, and a guest bathroom. This floor has direct access to the
