The windows and door make up the D & H, too obscure?
Yeah did think about a single brick, 3 bricks and then house but how do you put that in a logo lol. We're based in Shrewsbury, the birthplace of Darwin so it is a cool idea, no idea how to implement that mind.
I'm going to be a little different, I don't like the ISO one, probably because I'm just seeing the technicalities of it which are wrong (you wouldn't see the 'hidden lines' or they'd be a different line weight). The lettering is a little obscure too and the 'windows' aren't at the same angle.
I kind of like the idea of the first one though, it's not perfect and I'm definitely not keen on the font choice but I kind of like the simple 'roof' shape (lose the vertical 'wall') and think you could maybe play with that a bit more. You could also do a 'condensed' version using just DH.
Just a random thought and not sure how this would actually play out but what about making the DH into a 'terrace' of houses.
I think you have to be really clever to pull this kind of thing off but I totally think this one's very much getting there.
I like the one with four stages and although the negative space for the door and the I is nice, it doesn't balance as well as the one that aligns to the right but it's personal choice.
I can instantly get the Darwin, building and the evolution of man thing.
