Mabox buildings to three.js scene

I am using mapbox and three js in a project where I would like to:

  1. Query the geometry of buildings within a given distance from a position. (All buildings in the same layer within a given radius)
  2. convert these geometries to three.js meshes and add them to my three.js scene.

I have set up the scene already but does anyone have inputs regarding how to to the ideas above
