I personally like the logo, perfectly designed and very clean. Looking at the previous one, you can easily tell that you have worked on it very nicely. Keep it up
The thing is if you look at a row of identical houses, they will look like a graph from a distance too, especially if they're doing the staggered build a lot seem to do now.Just noticed it looks like a graph increase too - double edged sword with this.
You could use the house shape for bar charts etc. in infographics.
