TDV Constructions Pty LtdLogo Design Contest

i think it is all a bit conservative can we make it more modern. i do not like roof and building shapes as i have had it in the past. i like a lighter blue and would like you to come up with some contrasting colours.
I like the idea of a symbol picture etc not just letters.
i had an accident this morning cannot type with right hand only using 1 finger left hand a bit hard however as i am stuck home i will try and post comments.
I believe i need more time how do i extend the lenght of the contest as i was unable to asses entries over the weekend
