This branding/identity was for a group of construction and architecture+planning companies based in Berlin, Germany. I think the logo is simple, bold and memorable. I'm also tickled they transferred their brand onto tools too! I see that the chevron pattern also looks like a building, but I am concerned the logo might not be timeless because this bold chevron pattern seems to be trendy.
Diker Bau - The Teal Blue color choice posistions the the direction to the Sky, whereas the Red touch gives the brand the feel of warmth and heat from the sun. The Typeface part harmonically coresponds with the logo mark curves and helps to reach the balance in the whole Logo.
