Some houses are built. A very few are conceived. This is not an AI listing, this is real. MT Hood Views & 3 others when trees are trimmed. Hidden in Milwaukie, The Mountain House is a RARE, remarkably intact residence designed by legendary architect Pietro Belluschi in 1949-50 for J.D. Kroeker. Belluschi's original project is documented in the architect's archive as placing this home squarely within the period when he was defining what would become known as Northwest Regional Modernism.What makes this property extraordinary is not simply its pedigree, but its authenticity. More than seven decades later, the house retains its original character, materials, design, and even its original zonal hot-water radiant floor heating system, an innovative feature that reveals Belluschi's belief that beautiful architecture should also work beautifully.Set on approximately 3.1 acres, the home is an exercise in restraint: natural materials, warmth, light, proportion, and a quiet relationship with the landscape. Nothing feels manufactured for nostalgia. There is no imitation of mid-century design here-the experience is of stepping into the architecture as Belluschi intended it.Belluschi's legacy reaches from Oregon to the national stage, but his most revealing work may be found in the homes he designed to be lived in. This home is one of those rare places where architecture becomes inseparable from daily life.Uncommon to say the least. 3 beds, 2 baths, trees with Mt Hood Views. Original, enduring, and quietly extraordinary where the landscape become the architecture.
