I don't know what it was about the 70's but they built-in everything, down to a nook for a rotary phone! In our house the builder included this large built-in pantry in the dining space. I'm not sure how the people who lived here before us
only had one side of cabinets because this pantry is the
only space to store food. When we moved in I had to give it a massive scrub down because like every other surface in the house it was covered in smoke tar, but it was still remained that over-varnished orange color.
