Combining assets into one (blueprint?)

Hi, my question is next: what is the right approach to combine assets for instance, i got a house with windows and doors as blueprints set to match in the world, furniture, spot lights, and reflection boxes also. I would like to merge it all into one group so i can place it all together in the world so that all components match their position.
Also can I and how add afterwards more assets in that blueprint.

Make each element of house as a components and then in single blueprint place them in way you want, alternatively you can use child actor component to place actor blueprints as a components.


You can use Victory plugin for combining and convert static meshes to instance mesh actor. But keep in mind, instances work only on Desktop. Mobile not support instansing.
