Depending on the services required and the constraints of the property – Conservation Area and/or Listed Building, as designers we charge from 3% of the estimated build cost to 15% for a full service. We advise on a budget cost at the earliest stage to make sure the scope of the project is within budget before progressing. In some cases, clients prefer fixed fees for the design stages, and we offer this alongside providing quotes from the required consultants for consideration. We would strongly recommend an independent Quantity Surveyor to provide the budget cost analysis and contract administration throughout the project. Other consultants/costs may include: Survey – Topographical and measured survey of the land and existing buildings. Principal Designer – normally included in our fees to the point of the project starting on site. Health & Safety Consultant – as required for the design stages. Planning / Heritage / Conservation Consultant – We will advise you as these are not always required. Ecology / Arboculturalist / Land / Flood Reports - as required. OS / Land Registry Maps – expect to pay a small fee (£20-60) for the required map in digital format. Local Authority fees – may include a Pre-Planning application, Outline Planning submission plus a Planning Permission and/or Lawful Development fees. When on site all projects require a Local Authority or Private Company Building Control Plan Submission and inspection fee; providing regular inspection and certification at the end of the completed project. Structural Engineer’s fee – required in most cases. Quantity Surveyor – to provide ongoing budget cost analysis, tender analysis, and contract administration. Project dependant Consultants: Principal Contractor, Health & Safety Consultant Heating engineer, Energy Efficiency/ Renewable and/or Retrofit consultants, Kitchen/Bathroom and Interior Design services, specialist sub-contractors for swimming pools and leisure suites, lighting, and security.
