First to describe the exterior: the house is dilapidated, the lime wall flaking badly, the exposed bricks look dull; roof or walls with a little moss, appearing particularly old; doors and windows are rivers and rivers, stretched to the limit, a lot of places are broken seams, was pinched often up and down to open.
Then depict the interior: walk into the house, look around, the walls are yellowed, several places have broken holes; the floor inside the house is hard and uneven, pitted, obviously with the mark of the era; the corners of the walls hide cobwebs, there are flies or bugs in the corners, and there are bits of paper and rotten cloth on the wall or the floor, which are shattered at the slightest touch. Inside the house, there is no interior decoration, nor any furniture or decorations, only dust and rags piled up in a mountain, unbearable to look at.
Finally, it's the smell: the house is filled with a dreary atmosphere, the musty smell and dampness on the walls are unbearable, and there is also the faintly wafting rhyme of large objects. In short, the ancient dilapidated house has a strong color of the vicissitudes of time, and by describing it, the rendering atmosphere of the literary work can be achieved.
