Some of you may remember, that I've posted before about our family's dream concept for a multigenerational two-family home for that will be our retirement home and we will share with our daughter and son-in-law. We have been considering in a small "new urban" subdivision in a great location near the base of a ski resort and will probably make an offer in the next few weeks. The upside of the subdivision is the location close to everything and there are several very pretty duplex lots on a bench overlooking a beautiful mountain creek. The trade off and the lots are small. The lot we are considering is about 135 x 135 and has a building envelope of about 96 x 97.
The lot slopes front to back (south to north) and a bit west to east (Lowest point is the NE corner). A few of the key design guidelines are require one porch to a minimum of 100 sq feet, minimum width 10', minimum depth 8 even with or on the front plane; the west garage must be be side loaded; 60% of the front facade of the structure must be within 5' of the minimum front setback (porches may be used to meet this requirement). We would like to preserve at least some back yard space for the dogs and back yard fences are permitted.

I've sketched out a bare bones concept plan pasted below for the main floor and scaled it on a plat of the building envelope just in an exercise to try to get an idea if our idea would even work on this lot (and, besides, it was fun to do during some recent down time). The concept is to create separate private living spaces for each generation with the ability to share some spaces which may be technically part of one unit (Unit B in the concept) but arranged so accessible from both, while still preserving privacy between units. Goal would be about 4600-5200 sq ft. living space, excluding basement, (approximately 2300-2600 sq. ft per side). Unit B (older generation) must have primarily one level living for us, but may have a guest suite upstairs. Must have an office that will also occasionally serve as a snore room, but may be utilitarian. Unit A (younger generation, possibility of a child in the future) should have living down and 2 bedrooms/2 baths up, but potential for a bedroom on main.
I haven't even attempted to draw the upstairs of either unit or the basement. If we move forward we will use an architect, who will probably scrap the whole thing, but at least walking thru this might provide a starting point for the conversation and will give an idea as to our priorities and how we want to live. We probably won't build for a few years, but when we do, we will use an architect, so repeating this is just a conceptual design trying to see if the purchase is even worth pursuing.
My primary question is do you think this will work? This is JUST a concept plan and is missing many details. I don't want to go down this road and later find out that to be able to build what we want given the space lot constraints and budget. Just FYI. Somewhat comparable newer duplexes and town homes sell between 500,000 and 700,000 per unit. Outs would be mid-grade, nothing fancy. I hope this to be all in, lot plus house for about 2 times that (2units). All cash, no financing.
Sorry this is so long. I omitted a number of things. I would be very grateful for your imput, on overall layout, etc. (so long as it doesn't add additional cost or size). Btw, I did layout furniture in this and I think it works). Any imput on how to manage that long hall would be great.
