It's as close to a relationship with your home as you might ever feel. It's about feeling the soul that resonates through these walls, through these rooms and throughout the private outdoor living space which reminds you that you're home and that everything's right. When they talk about unique style, this property comes to mind. This home integrates with nature, sharing space with several tree species, a live pond and where bees sip nectar and birds sing. The west facing backyard living space is like no other. A sense of quiet and privacy emanates from every corner of this oversized lot. Let the burbling pond take you away to another place and time where the wind is the music. Combining traditional foursquare design with Japanese aesthetic and with materials and color palette here coincide with nature and make up the unique design and where strength and durability reign. If the home has a soul, then the main living area may well be the heart, with intentional and supremely functional design with 9' ceilings, a wood burning fireplace, rich crown molding, a large staircase and tall custom wood shelving. The renovated kitchen will entertain forever with custom soft-close drawers and cabinets, custom lighting, soapstone countertops and professional grade appliances. It's a community space for sharing moments around meals and stories with friends and family. With wood floors throughout, a large dining room, two living rooms and a custom wood-clad private study and a fully finished lower level with a large bedroom, three-quarter bath and separate walkout entrance, this home provides the ultimate in space comfort. When they talk about relationships, this home was built for it. It is a home that understands and responds to the improvements and updates. It's listening. To give is to get, and this home gives. There's a soul that resonates here, just ask the owners of the last 40 wonderful years, and you'll know. It's the sigma oasis - you're already there!
