Conant Rd is deemed a scenic road which can have effects on properties located there. It would ultimately depend on the highest and best use of the home that you were previewing for sale. I would be more than happy to discuss this further and you can feel free to visit my website.
I have lived in Weston for 12 years, and I actually lived on the corner of Conant and Pigeon Hill Roads when I first moved to town. Conant Road is a busier road in Weston, but there are many beautiful homes on it - at all different price points, even some that are multi-million dollar homes. I would be happy to discuss this with you in greater detail if you'd like - please call or email me.
