What you mean 16x16 you have to put the house together yourself with 16 bit tiles or ? or what part of the assets are 16x16, sorry I'm a bit confused though the pack looks quite normal with the colour pallet nice work there as far as I can say.

Hello! the interior of the house contain 16x16 tiles, and some larger furniture like 32x32.
For the interior, you will necessarily build with the tiles all the house.
For the exterior, the package contains larger roofs and walls to make it easier to build. also the package brings a png with ready-made houses.
