DO NOT make the house an entity period.Rather split your house in sections.Floors ceilings and walls and make segments.
For floors to work correctly they have to be 100 x 100 units either the height or the length may be shorter for example 100 X 50 units.
Both height and length may be smaller but there is no guarantee that it will work correctly.
Walls and Ceiling have to be above or below crawl or jump height for proper collision period.
A single entity with ceilings floors and walls as a combined mesh will NOT work.
It is recommended.....well I am telling you that entities will NOT work correctly 100% even with no or reduced collision, any thing that either the player or entity needs to walk on HAS to be a segment and comply with 100 unit by 100 unit rule to work period.
