Are you looking for Modern Architecture House Design and have $10 million AUD in their bank accounts or can get a loan for that, I advise you to take a look at this Modern Architecture House Design called Walker House, in Sydney, Australia.In an exclusive and tranquil neighborhood located at 20 Lentara Rd, Bayview Heights, the $9.7 million USD (or €6.1 million) house packs 4 extremely modern bedrooms, 5 bathrooms, 3 garages and one lovely in ground pool.What got my attention? The Modern Architecture House Design, the vast ceiling spaces and the huge outdoor sliding glass that makes it look like a part of nature, plus the fact that it uses underfloor heating. Oh did I mention the 8 person outdoor spa? Guess not.If these things aren’t enough for that money, then here comes the cavalry: a championship lawn tennis court, cinema, smart home technology, more than 1 acre of manicured grounds, reverse cycle air conditioning, split-faced travertine and lots of terraces and recreation spaces.
