Pricing

Every project is bespoke, due to site conditions, existing house, client brief and technical considerations.

However, below is an outline guide to fees for different scales of projects [updated April 2019].

Further to carrying out an initial consultation, I would provide a fixed fee for stages 1-4 for your project.

The Tendering and Construction phases are charged on an hourly rate, depending on hours accrued. Ad-hoc site stage services are not provided. VAT is not currently required to be added.
