Place them both on the same UV space and use just one texture for both items, that way you save up on resources.
It is better if you do a 2K even 4K texture for it, so you have enough resolution for if you want to show your asset separately in close ups and stuff. Then for the actual interior house scene you can down-res and create a 1080×1080 out of one of those high res, so we save up on memory.
