As an AI language model, I cannot provide real-time information. However, if you are inquiring about a specific house or famous interior design project, it is possible that original drawings, plans, or documents related to the interior design may exist. These can include sketches, blueprints, mood boards, 3D renderings, material swatches, and correspondence between designers and clients. For specific cases, it would be best to research the particular house or designer you are curious about to find more information on their documentation or collection of original design materials.
