Should I convert my house to a static mesh?

Hi I am kind of new to unreal and I have been wondering, should I convert my house to a static mesh?. So far I have just been making it out of geometry blocks and I heard that it will take long to load and it will cause other problems in the future should I convert it to a static mesh or do I have to start over?

It should not make much of a difference if you just leave it the way that it is. If you want to convert blocks to a static mesh, I would recommend to watch this video Converting Geometry (BSP Brush) to Static Mesh - #8 Unreal Engine 4: Level Design For Beginners - YouTube . There is no need to start over if everything is working well.
