Following Mike Oehler’s life work with underground housing added with Finnish traditional log cabin building. https://undergroundhousing.com/ My dream home plan (Luxury versio) – Kitchen and bedroom– Music studio– Sauna + Movie corner + Art working places– Underground “castle like” hallways connecting each section– Fireplaces in each and electricity 100% from solar panels Kitchen and bedroom section digging progress: too much huge stones came out, I then started digging other places but it is going to be too swampy as they are on flat land. I would need dynamite with this. Mike Oehler’s idea. Basic structure. I dream about making 7-corner model build with finnish log cabin style. First ideas. The chimney must come out from the front to take all the heat in use. Rocket heater is also one idea what I am thinking to look for.
