Create four graphic images

This project is for four black and white graphic images. The style should be simple, and use clean lines, imitating architectural drawings. However, this is not a drafting project. It's for drawings or CGI images. The first shows a standard tent on a platform (see illustration). You'll have to make the platform larger than shown in the illustration. The second shows a very small house on the same platform (see illustration). The third shows the platforms (approximately 25) laid out on a grid pattern with tents on them. The fourth shows the platforms (approximately 25) laid out on a grid pattern with very small houses on them. There should be no background images, landscapes or scenes. There should be room enough between the tents and very small houses for people to walk. Imagine that there are four meters between them, and 'boardwalk' style sidewalks (see illustration). As the graphic artist, you'll have to "make it work." I don't have the measurements for the very small house. The illustrations should all show the platform as the same size. Please look at the images attached to this project, and do your work based on those. Please don't add any of your own designs or design elements wihtout approval. I have posted projects in the past that got bids in the thousands, but were completed for just a few bucks. Please be competitive in your bidding. Please link to your portfolio, if you have one.
