Going to parrot below comments here and say that it's very hard to tell what's going on and that's a bit detrimental to the overall experience. Other than the camera zoom-out, maybe make it clearer as to what house is coming next, as the indicator at the top of the screen is a tad hard to read visually, at least for one of the more detailed house pieces (the long rectangular one). Maybe having the houses be detailed 2d sprites (like in the thumbnail) could help with that. Something that could also help is having the floor lighten up on the platform to indicate where exactly the piece will fall.
This is a very interesting concept, almost like physics-based 3D Death Tetris, which is super neat. I'd love to see it fleshed out a bit more!
