Josh Grant just answered a similar issue [here](https://forums.unrealengine.com/t/i-cant-build-on-my-uefn-map-even-on-custom-mesh-or-fornite-props/2448050/3)

For quick reference:

> From my experience, this is the best flow for making custom meshes that support player builds:
> 
> 1. Create a Blueprint and select the Building Prop option.
> 2. In the Blueprint editor, select your mesh
> 3. Enable ‘Is Player Buildable’
> 4. Enable ‘Do Not Block Building’
> 5. Enable ‘Structurally Support Overlapping Actors’
> 6. Compile your Blueprint
> 7. Drag your Blueprint in
> 8. Build on it!
