As far as covenants go surely we all have a bit of common sense here to realise that unless they stipulate you can ONLY build a house ONE particular way, that there will always be a bit of variation in what people build. If you look at your estate covenants and what they set out, then compare that to the houses built that aren't to you taste, you'd likely find they actually comply with the covenants guidelines.
Not at all... if the house complies with the covenants, it can still be ugly and tasteless - but that's a whole other thing. It doesn't take a genius to understand that pale, pale beige is NOT the same as dark grey.
Um I think that was kind of my point?
