Don't overthink, relax, visualize it and enjoy the adventure!

Just about any color will work on that style of house.COLOR VISUALIZER

Yes, basically I'd like a relatively cheap system (say $1000 or less) where the FedEx guy (or anyone) can call the tenant, it rings on their phone, they can visually see who it is, and click a buzzer to let them in.

I can see where they would make a big visual difference, but the quality seemed very low and they felt very cheap.

Try to stay away from adding a row of similarly sized and shaped shrubs along the foundation - it's already quite boxy so you want to use landscaping to create a little visual interest with heights, shapes and colours.  

Also...everyone has some really good ideas it seems but honestly it is hard to visualize from simple text.

Obviously I'm not going to be putting walnut doors and granite countertops in the houses, but I will make sure they are at least structurally sound and visually appealing.

Google maps or any map service, actually, can give you a visual on banks on location.

No need to tie into the rest of the house, since there are units that can be used just to condition (heat and cool) a small space like that.I believe that the electrical wiring can be surface mounted in channels or in conduit or in metal jacketed cable, but those aren't as visually attractive as being behind a wall.You want this to be living space - anything in particular (family room, office, etc)?

It was a nice visual I was hoping to borrow for something I'm working on.Thanks for looking, though.
