I see the INTP macro-cosmos represented in my micro-cosmic idea of the ultimate home:
INTP houses would be designed by many small INTP architect firms to suit each individuals personal preference for space, utilisation of space, and as an abstract and also highly functional representation of their inner world.
For example, my house would be a small, minimalistic, ultramodern design with plenty of covered outdoor area so that I could enjoy scenery from all sections of the house. Solar panels would generate electricity and heat water, etc. I would trap rainwater in large tanks, and recycle all waste water through a communal multiple reed pond system, which would create habitat for wildlife and birds in close vicinity.
Internally the kitchen would be the main hub of the house, completely set up like a professional kitchen with stone surfaces all around and industrial type equipment for easy and effortless creation of highly nutritional meals. Adjacent would be a library/meditation/thinking room which would have walls lined with bookshelves and comfortable seats and floor cushions all around.
A separate area for entertainment: I always wanted a pool table, so a room dedicated to "INTP sports" such as darts, chess, pool, poker, etc...even an Ouija board for the more "out-there" mystical nights with a couple of friends
I would also like an atelier/workshop/laboratory complete with microscopes, chemistry equipment, camera gear, dark room, stuff for painting and electrical tools for fixing/inventing or building stuff.
A small observatory connected to my bedroom which would have partial glass ceiling that could be electronically darkened to shut out all light.
As far as furniture and other house necessities are concerned, everything would be designed with the idea of functional art; ergonomically designed as well as aesthetically pleasing using recycled materials where possible, and a subdued colour scheme for an overall calming effect.
Everything would be of a functional industrial as well as aesthetically pleasing design by many different talented designers and artists; the equipment would be sold through a co-op system which would exclude the middle-men, hence it would generate more work for small businesses and encourage personal invention.
I would fill the whole house with green plants which would give the place an overall lush look to break with the ultramodern designs, these would generate enough oxygen and keep the indoor air at optimal quality during the winter months.
And of course a music room, complete with Hi-Fi set up, computers for composing; a piano, violin and my vast music collection

, turntable, etc...
I can see an INTP culture as a larger version of my personal home, the culture would be based on learning, exploring, new invention, personal expression through the arts and sciences as the appreciation for art in all its forms is another form of scientific expression, or you could also reverse it and say that science could be artful....they go hand in hand and are equally fascinating.
And one would not need long holidays as a society based on this kind of lifestyle would produce content individuals with less longing for escape. One's work would be enjoyable, and one's home would be a sanctuary; sustainable living would require one to work shorter hours as the energy bills and rental fees would be more or less a thing of the past.....
And humans would have the required spare energy, calm and subsequent inspiration in order to evolve as a more noble, intelligent and refined species.
