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.

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 not required to be added.
