I would want braille labeled appliances. Also, make every light switch give off a sound when the light is first turned on, so I could tell if I had just turned the lights on or off.

Well-lit stairs with high contrasting edges on the steps. Some steps at houses (especially hardwood floors) are death-traps, especially among older people. For people with significant mobility issues, an elevator or lift along the stairs, but size of the house would be a factor.

Adjustable lighting. Full Spectrum bulbs if possible. Even better if voice controlled instead of a switch, but switches should be good for most people. Some people find too much light to be bad, others find too little light to be bad. Make it adjustable so they can decide.

Heated path/driveway for northern climates. Makes it so much easier to travel when there isn't ice/snow on the path.

Honestly, I don't know. I'd do the obvious (make everything high contrast, design the rooms so you couldn't easily trip over things, etc)w My two first ideas would be;:

* Put full Dolby Atmos surround sound systems in each room, wiring them all together in such a way that any room can choose to listen to any source, so you could, for example, start a podcast on your phone, then just walk into the kitchen, flick a switch and the sound would follow you. This of course comes from audio being important to blind people (at least to me, anyway).
* Abolish round tables. This is very much a personal thing for me, but I hate them. They're either in the middle of the room, which is the most efficient place to put them, but means it's much easier to walk into things when crossing the room, or they're in a corner, which wastes space and leaves gaps, which just bugs my OCD.

I've discovered from writing this not that I want to live in a mansion, but that I have a very strange, specific design taste.

oh man this is a good question. heres my list
1: No corners except for doorways. This means the counter as well. Also the counter needs to be level with my belt. You have no idea how many times my counter has kidney punched me. I have literally split my head open on a wall courner. Screw corners.
2: acoustics need to be well thought out. setting it up where kitchen noises make noise only in the kitchen. Where the doorbell can reverberate throughout the house. Set it up where footsteps echo in hallways but not in openings.

3: Chairmolding: That wall moulding that you can place in the center of the wall. To stop chair tops from hurting the wall. I use them as a tracer for my fingers while i am walking, that way I dont get fingerprints all over my wall. I don't see the fingerprints, but it is always nice to surprise people. "How do you keep your walls so clean?" ""because i gave myself an area i am able to touch. then all i need to clean is the moulding.

4: Every doorway makes a small noise when aproached. Same for windows. the noise can change for : Open/closed/ajar/locked/unlocked

5:suspended wood floors. face it blind people drop things. Stuff has a higher chance of survival if it lands on a wood floor. so much glass has been lost to tile and cement :(

6: Installed with a smarthome system of somesort. Just make sure that it is locked down, we dont need our houses and doorways whispering to us in the night.

7: Exterior: This is important. Make a clear sidewalk to the mailbox. Then put a fence up. Trust me man that little critter scurring around get alot creepier when you can see it. also a garden of nice smelling plants. Make sure there is a hammock in the backyard under the shade of a tree. Make sure there is a path to that hammock. Also get a robot lawnmower, better a robot cut my grass than me the blind guy. lol

The furniture is built into the walls and floor so theres no under/above space collecting dust that needs cleaning.

Maybe a 'workstation' with a pretty big screen.

A place to park my lambo

Different textured walls so you know what room you're entering/leaving. It would help a bunch when first getting used to the house.

Also, stove/oven that's voice controlled. Putting your hand over a flame to see how high or low it is isn't a good idea lol

Everyone has awesome responses. In addition, I would like a spacious workspace to accommodate bulky assistive technology and accessible materials. I enjoy hard copy Braille books, and I want to have plenty of shelving space to store them. I would want large desks with several drawers. This might sound odd, but easy access to multiple outlets is essential since some visually impaired people will often have extra devices to charge.

We want to build a house in a few years and I think the things I want could mostly be accomplished on a reasonable house-building budget.

* Really good lighting throughout that's voice controlled
* Smart thermostat that's also voice controlled
* Of course this means an Alexa/Google Home type device in every room
* Good audio system throughout to go with that
* A really big TV
* Hardwood/tile flooring in general, but if there's carpet, I want it to be the really nice plush kind
* Cabinet doors with hinges that make the doors close automatically, so I can't accidentally forget, leave a door open, then turn around and bang my head
* Under-cabinet lighting for well-list countertops
* Pantry/interior cabinet lighting in places where it makes sense
* Cabinets with large drawers for storing pots and pans, because it seems like it would make things so much easier to find/access
* The kitchen island should have rounded corners for all those times I'll inevitably walk into it at night.
* A securely fenced yard with good exterior lighting - and by that I mean a well-constructed fence that I don't have to worry about the dog finding/making a gap I didn't see, not necessarily a security fence.

Now the pie-in-the-sky things I want that I'm not going to get:

* Heated driveway/sidewalk so they wouldn't accumulate ice in the winter.
* Someone to clean it for me at regular intervals. ;)

Probably some pretty strong lights, and enough cooling to keep it cool anyway.
