Building a house is an overwhelming process and usually designed 'backwards'. You look at plans and find ones you like that may or may not meet your needs. Higharc has software that allows you to 'flip' the process and start with your needs and then generate 3D plans from there. With the 3D plans, you can visualize your plans completely to 'try on' the design of your house. You could even envision this paired with virtual reality to take home design to the next level. Higharc has raised ~$5m to bring their idea to life.
