House sketches and ideas

I was struggling with getting the idea of how the houses would look in the world, because they cant be too neat and tidy because the water level is always rising slowly. In the book the buildings are described as being built up on top of the buildings below the water level, and all the parts such as the windows and door frames are then moved up above the water level, so houses are stacked up and built on top of each other. Above are some useful reference images that are relevant to what i need. 

 

Here are some sketches i came up with for a general idea on how the houses would look. i liked the idea of having cranes and winches set up on top of the buildings so supplies and building materials can be pulled up to continue the building process, but also to dry out wood and other materials so they are safe to use.
