We have some very good quality builders in Manhattan. However, i would recommend you contact the Flint Hills Area Builders Association at (785) 532-9080 or firstname.lastname@example.org. Building a house is a very personal experience and you should build with a builder that you are comfortable with and who knows your wants and needs. I would highly recommend interviewing at least three builders before you decide who to build with. Also, the time of year is critical because many of the builders are already building custom homes for other people and they may not be able to get to you until a year out. Most builders in Manhattan already own their own building lots. It is highly unlikely that you could come to Manhattan and purchase a lot to build on within the city limits.
