Your logos definitely seem to capture the feel of Barcelona. We have two pieces of feedback to consider.
The first would be to continue to explore the color palette. The second is just a view into our thinking. What we're bringing to social housing projects is a lot of new technology and one of the ways we're able to rapidly build these large scale developments is through the use of uniform materials/panels. The more organic nature of your designs doesn't really fit that. However, we might make a decision that a bit more organic logo softens our image and offsets what we do, versus reinforces it. We don't know the answer yet, but wanted you to have the benefit of knowing that is something we will be considering.
