I had not realised how many different consultants you can invite into a project like this. The consultants that our architect is engaging are as follows:
Structural engineer – who also provides civil engineering services which, I think, means anything under the ground as opposed to structures above the ground, load bearing and materials. I wonder whether the civil engineer advises on the borehole, sewage treatment plant and other water management.
Mechanical/Electrical/Environmental consultant – I presume they play a central role in designing the off-grid elements of the building, energy needs and provision. I wonder whether they have input into the design and choices about the water management as above.
Quantity surveyor – I think this person can also recommend the use of alternative materials that might be cheaper.
VAT consultant – I didn’t know these people exist but can see how important they are because some elements of the build are zero rated for VAT while others attract 20% and some a reduced rate. They cost about £1500 and I can see they could save much more than their fee.
