This logo ranks first so far. However, our team is concerned about the oval shape. While we don't mind buildings, it is not a must to have a high rise on the logo.
Yeah, we don’t mind have buildings in the logo. However, more than half of the commercial renovation companies here have a city skyline in their logos.
I was thinking today to explore the buildings idea in another dimension: trough architecture drawings symbols (golden ratio, cross-section, etc); more in terms of inspiration for an abstract (or pictorial) mark than a direct reference to an architect’s firm.
I look forward for your proposals, and wish to interact with you to make a great logo.
