Hello, I like # 100 because of the building plan in the logo. This idea is good. yet It is a regular plan i.e. this logo would have worked as well for an architect. What is missing in my sense is 1. the link to offices that are or specific area of expertise and 2. the transformation/rejuvenation Idea. We need to express in that logo that we relift spaces and transform them to a better, sexier or more productive places... Can the background plan eventually change from left to right to express that. It is just an Idea...
Last comment is that I do not get the point on the "L": does it mean a person on a desk??? Please clarify.
