New Logo for Achitecture Company

Krenzer

Architektur in Glas

We build hiqh-quality, high-price conservatories and modern extensions with great windows, clear geometrical lines and flat roofs. Maybe it would be best if you had a short look on our website: http://www.krenzer.de
We increasingly sell minimalistic glasshouses with extraodinarily large glazing elements, in the so-called Bauhaus style, for instance to enlarge the living space or to roof a swimming pool. Besides that we also offer modern and Victorian conservatories but the logo should be rather abstract/geometric.
All products are made in Germany and we do our best to achieve the highest standards of quality.
Our typical customer segment are wealthy private individuals, and more and more also hotels and restaurants.
Besides that, we growingly cooperate with well-known architects to directly sell the glazing elements. In this regard, we intend to expand into the high-end architecture scene. Thus, it would be nice if the logo could convey this, too.

See old logo uploaded.

I have uploaded two files, among that our single old logo with some rounded corners and colour gradient. We think that this is outdated now and therefore we would like to renew it. We have already tried some new designs on our own (see the other file with various drafts).
However, we are not yet content with those ones, but we hope that you recognize the direction. The logo should fit our new website (http://www.krenzer.de) which is much lighter and more minimalistic than the old one. It should be clearly structured without any curved design and contain our company colours (orange and (light) grey/black). Please use the same orange as in the logos uploaded. Furthermore, the logo should include a visual icon that may be rather geometric and abstract but relates to our portfolio in some sense, for instance our minimalistic glasshouses. It should be well recognizable after some time by our clients. In contrast to the old logo, it would be nice if it was more filigree and sleek. Maybe it would be more modern not to use any gradient colouring like in the old logo. Moreover, it should show our new slogan 'Architektur in Glas', possibly in capital letters.
It would be great if you could check out our website (http://www.krenzer.de) first as the logo should be in line with it. Many thanks in advance!
