WiFi enabled HA is a bad idea. Please one of my earlier posts as to why. To recap, though (since you're self-proclaimed lazy and all): Wifi is subject to a single transceiver - that does not automatically extend. This is a big problem in tight spaces, because generally the smaller you go, the worse reception / transmission power you'll have in these systems. What you want is a mesh network (i.e. ZigBee, Z-Wave, Insteon, etc) that will automatically handle the mesh aspect of being able to continually extend itself as you build out. It is also much less maintenance long term as well (for a variety of reasons). But if you think that there aren't drop in replacement wall switches already - there are. Aeon Labs (http://aeotec.com/z-wave-in-wall-switches http://aeotec.com/z-wave-in-wall-switches) makes some killer stuff that is in-wall, and there are a multitude of others. Check it out - everything you want is out there. And you can build an entire HA system in a decent size living space for far less than $750 USD.
