It is one of our primary services to ensure the safe and high-quality execution of construction projects. This involves conducting on-site assessments, holding discussions and advisory sessions on proposed plans, conducting site measurement surveys, and creating comprehensive photographic documentation.
It is the service that our proficient team will coordinate with the council and manage the entire submission process on your behalf. It does not include the planning application fee and permitted development fee themselves.
The costs for planning and drawing, site surveying, council submission, and building regulations will vary depending on the size, location, and type of property. Additional fees may be required depending on the condition of the property and the services needed. These charges will be calculated based on every aspect of the planning process.
Your written proposal confirms the scope, deliverables, programme and fees before you appoint us.
