The biggest complaint I've had about my homes is that they weren't built in a forward looking fashion.
All of the wiring was designed and installed in a fashion which requires the house to be gutted to upgrade it to code.
Some of the materials used were designed to be replaced or fail (eg. cheap orangeberg sewage utility plumbing), with difficulty in replacing.
No foresight was given to the durability of the structure (eg. having to replace the roof every couple years due to hail) in terms of costly maintenance and time.
So for my list:
* The structure would be a large monolithic dome, for durability.
* The entire structure would be built with 'false walls' between the living space and the exterior wall(s) to allow for easy access to eg. power runs.
* There would be a raised floor, to allow for easy access to...
* Heating, which would be run in a similar fashion as electric, eg. under the floor water heat, provided by eg. pex tubing.
* Since the structure is basically a large faraday cage, fibre would be run to an external structure to allow for outdoor wireless technology expansion.
* Solar would naturally be integrated, with the wiring put in place to allow for future expansion if necessary (both in the utility room via additional capacity on the fuse box, but also at wherever the power is generated). If Google can leave a large amount of their fibre dark to await capacity, I don't see why I can't do this with copper.
* Several additional sub-juncture fuse boxes would be placed throughout the house - one for the kitchen, one for the garage, one for the basement. Just something small. No point in having a purely single-star power topography.
* Solar concentrators windows/lights on the roof would assist by providing light to the house while at the same time powering solar.
* The house would undoubtedly leverage geothermal for power (hopefully) and heating/cooling, as heat exchangers are quite efficient and monolythic domes have notably low energy cost.
* Large windows (where appropriate) would have the newer panes which automatically dim the environment and/or can be used for projection purposes.
* Power outlets would be placed every 5 feet along walls and counters.
For security, I would likely install something like UniFi (ubiquiti) based cameras. I'm a fan of their power control systems as well, so those would also be used for lighting and such. I'd probably also consider using x10, simply because it offers a bit more flexibility and no lock-in.
But then, replacing eg. in-wall power outlets is fairly straightforward.
