What Does the Change of Use Planning Permission Process Involve?
The first step in the change of use planning permission process is to figure out the property’s current “Use Class” of your property according to UK planning law. Every building is given a use class — like Class E for commercial or C3 for residential — and if you want to switch between them, you may need permission from the council.
Here, an architect decides if your change is a permitted development or if it requires a full planning consent. The purpose is to reduce the risk and speed up the approval process.
Such stages normally consist of:
- Understanding the existing and the new use classes.
- Creating design drawings and a planning statement.
- Making the application via the Planning Portal.
- Communicating with the council for comments or changes.
Pointing out a precise, well-structured application could be a huge time-saving tactic, e.g., months of delay could be avoided — and this is the main reason professional help is indispensable.
Meeting Planning Permission Change of Use Requirements
Each local authority has different criteria for a planning permission change of use requirements based on their local development plans, conservation policies, and environmental impact. By meeting these criteria, you make sure that your project is in line with the community’s objectives and at the same time, keep the design intact.
The core requirements normally consist of:
- Correct site and location plans.
- Current and proposed floor layouts.
- A Design and Access Statement giving details of the usage and the impact.
- An environmental or heritage assessment, if necessary.
Studio 20 Architects is always coordinating with the planning departments to be sure that all the paperwork is up to these standards, thus the risks of refusals or further questions are minimized.
Understanding the Change of Use Planning Permission Cost
An application for a change of use planning permission cost is going to be different by property type, location, and how complicated it is. A simple application may only require a few hundred pounds in local authority fees, whereas a complex development might need additional surveys and reports.
If we talk only about the fees charged by official authorities, it is the most clever investment to have professional design and planning support alongside, thus, your project will be approved at the first time.
Cost considerations include:
- Money needed for local council application.
- The cost of architectural drawings and the preparation of the technical documentation.
- The cost of planning and design consultancy services.
- The cost of additional assessments if the property is listed or in a conservation area.
At Studio 20 Architects, we believe in clear pricing that is inclusive of everything from the drawings to the submission thus our clients can make their budgets without any hidden costs.
