It's a 15 y/o house with architectural shingles.

They can also give you a good idea about construction costs (in Seattle we cant built a home for less than $150/s.f. right now).Here is what I would do- print out a picture of the floor plan you like, look up 3-4 different architecture firms in your area and call them up (make sure you ask if they do residential, many focus on commercial), make an appointment and bring the floor plan, make a list of questions that you have for them (see list below), take dubious notes and have them all give you a proposal.

Almost all the construction managers I know have this degree, but some have degrees in construction technology, project management, or architecture.  

Consider what work has been done on the comps, because a raw piece of land vs. a prepped piece of land vs. a piece of land with an architectural plan and permits are not the same value.

The city permit center is also quite helpful, and they will help you navigate the approval process with the Architectural Review Board.

I am looking to build a shipping container apartment - does anyone know of architecture/engineering plans for sale?  

I am working happily as a principal at an international architecture firm based out of Kansas City.

I've had my eye on the North Avenue corridor between MICA and Broadway (surrounding immediate communities) and Penn North.I attended Morgan State where I studied architecture/planning.

I would like to use my architecture background to do some interesting (but inexpensive) designs in rundown properties to maximize profit potential!  

I've been in the KC architectural/construction community for 31 years for my day job and work with a number of multi-family developers.
