Special Extension / Conversion Packages

We pride ourselves on offering our clients a one-to-one architectural service that provides the lowest cost architectural drawings in Leeds, Harrogate and West Yorkshire, without comprising quality or technical knowledge.

Below are our special packages that can save you money in the long run. If you order your Planning Drawings and also your Building Regulations in a combined package and they are compiled at the same time (rather than waiting for a decision from the planners before getting your building control upgrade) you can get these packages at these reduced prices.

Structural Calculations

To ensure every client gets the best possible value for money we do not provide structural calculations in our packages.

If you think that you will need steel supports for proposed openings etc, then as a rule of thumb you should expect to pay about £150.00 in structural engineer’s fees for each steel beam that you will require.
