Explanation:
There are three main things that should be implemented/incorporated into your design and these are Access Points, Home Server, and Virtual Assistant/IOT connected devices. Access Points for Ethernet, and HDMI should be located in various important walls near outlets. This would allow you to easily connect your devices without having to run cables around the house. A home server will allow you to easily access your data from multiple devices in your home, and if you connect it to the internet you can access that info from anywhere around the world. Lastly, would be a virtual assistant with IOT connected devices. This would allow you to control various functions of your home with your voice including lights, temperature, and locks.
