How long will it take to get plans for construction?

It depends upon the size of the project naturally. But some guidelines are as follows:

Design of project with client: 4-6 weeks depending upon size
Request of Permit:
         - Maplewood: 10 working days
         - South Orange: 21 working days
Construction Documents: 4-6 weeks
Bid Process: 2 weeks

Thus if you are planning to do a project you have to start meeting with the Architect at least three months prior to the time that you want to start construction.
