Services We Offer

We generate ideas and carry out design work for a variety of both existing, and new buildings. Using advanced computer analysis, allowing for accurate designs, particularly for geometrically complex structures, we ensure that the structural design is of the highest quality.  This process subsequently results in the production of construction drawings, details, specifications and reports.


​Virtual modelling helps the design team see how all components of the project amalgamate. By analysing past solutions, sharing experiences and skills, we are always refining our ability to design stable, durable, elegant and economic buildings.
