The package should reflect the local property type, neighbouring context, likely local authority expectations, and the stage of the project. In Harpenden, that means avoiding generic drawings that ignore planning, structure, access, or buildability constraints.

Yes. When the project needs to move beyond the initial drawing or planning stage, we can help align building regulation information, structural coordination, or construction-stage requirements so the package stays coherent.
