Today I want to show you an underground vacation home (located in Switzerland)that was designed by Bjarne Mastenbroek and Christian Müller [architectural offices SeARCH and CMA].
This only access to villa Vals is an underground tunnel which runs straight through the mountainside.
Wood & concrete are the main ingredients for this recipe.
I really wish I was there right now.
ps: Villa Vals can be booked for €1750 to €3450 per week, depending on the season
