One thing that is a given is that it would be good to orient your house with the long walls facing directly north and south if you can do that on your site. A decent overhang on the south wall will keep the sun out all summer while letting it in in the winter (if you have real winter) minimizing cooling and maximizing free heat.
It sounds like you are planning standard stick construction and materials. Would there be anything you would build yourselves, either now or later? (Four teenagers are likely to want more space than you have ) What kind of lifestyle are you looking at? Animals, gardens, ??
Sorry for my lack of info...I should know better. Truly apologize about that.
Location: Central Texas
Land: 7.5 acres
ETA: December 2017 full time homesteading
Plan: Homestead with large garden, rabbits, chickens, pigs.
House: Planning on prefab Derksen portable building for this first structure. It'll be 16x50 = 800sqft. Then we will also have two lofts for kiddos. We only plan on being in this building for 2 years. Like you mentioned, our kids will be much bigger by then!! We will have a 9 year old at that time. Then we plan on have a 360* wrap around covered porch for outdoor cooking and homeschooling.
#1-- We goal is to be debt and mortgage free!!! We have complete passive income that we can work from anywhere. So we want to start with this prefab and document us finishing it out. Then on the second building taking on more framing, plumbing, etc.
Designing a bathroom so that, either now or later with small modifications, it has separate compartments for sink(s), toilet and shower can let multiple people use it at the same time, making sharing much easier. If the bath is at the edge where the addition will join, part of the addition could be a relocated fixture that then allows the separate compartments to be built. It could also be directly accessible from the addition instead of having to go back through the house to reach it.

Assuming you intend to supplement, an obvious first step in interior layout is to plan for how you will expand. It sounds like your climate lets you be outdoors most of the year? If so, you may be able to have neighboring structures joined by a porch. You would want a plan that lets you either have your ultimate master bedroom now and expand for kids' rooms, or let kids expand into current MBR and you build new MBR in the addition.
Oooo! That could be a cool thought, turning our MBR into the kids room down the line. Neat idea!!
--When you say, "It sounds like your climate lets you be outdoors most of the year?" We are in Texas. So June-August is brutal here. Hot. Humid. Terrible. So finding a way to place the structure is top on our list to get as much passive cooling as possible.
PORCH-- YEP! This is our plan to attach the buildings with a covered porch.
Glenn Herbert wrote:For bathrooms, your video discussed master bath versus guest (kids') bath; would you ultimately want three bathrooms, or would you want the addition to easily access the current bath? Three bathrooms doesn't even sound like small house to me, never mind tiny
ha ha ha ha!! You are correct...3 bathrooms doesn't sound like small. But hey!! I will have 4 KIDDOS!! lol My wife just keeps wanting more kids.
So the long term plan would be 1st structure (16x50 and two lofts) to house all 6 of us. MORTGAGE FREE!! Then a year later build a 12x14ish guest cottage. If we need this to house our big kids then that'll be great. But I honestly think we will plan something different if we have another kid or once our bigs are teenagers.
LIKE A TRUE TINY HOUSE ON WHEELS!!!
We plan on our property to be an Air BNB of sorts.
First, I would plan the loft. Do you plan to have a bath in the loft? In the middle by the stairs? Then decide where you want to put the stairs.
A friend of our made child size stairs as in the width of the steps. When the kids got older the stairs had to be rebuilt to accommodate adult size feet.
Next I would design the bath/baths. You will want to keep all your plumbing in a central area to save on costs. Then the rest of the house can be designed.
