Preparation of a design brief, feasibility studies, planning and Listed Building applications, construction drawings and specifications, tender invitations and contract documentation, contract administration and on-site inspections, models and perspective illustrations, building surveys, advice on building defects and landscape and external works. Both modern and traditional methods are used to create plans in the practice. Hand-drawn plans are usually submitted for Listed Building applications as their appearance is more suited to those generated by computer aided design (CAD). But modern technology comes into its own for producing plans for Building Regulations approval. CAD drawings are flexible and faster to produce for on-site working drawings.
