We don't use exterior photos when building your 3D model as it isn't possible to trace an image capturing an unlimited space (such as open sky) inside the model without creating significant distortion inside the final result.
When building your 3D model we will use only your interior photos. If you have a terraced space or a balcony it may be possible to include this inside your 3D model if there is a significant overhead covering that our team can use during the construction process. However do please note that this doesn't guarantee that the unlimited space won't still appear mildly distorted inside the model.
