Preparing accurate planning application drawings is one of the most important steps in securing planning permission for your building project. Whether you are planning a house extension, renovation, conversion or new build property, professionally prepared architectural drawings for planning help ensure your application meets the requirements of your local planning authority.
Our Chartered Architectural Technologists provide detailed planning permission services for homeowners, developers and businesses across Cheshire, Manchester and Yorkshire, guiding projects from initial concept through to submission.
If you are extending your home, clear and compliant planning drawings for extensions are essential. These drawings communicate the design of your proposed development to the planning authority and demonstrate how the project will sit within the surrounding environment.
Typical house extension drawings prepared for planning applications include:
• Existing and proposed floor plans
• Existing and proposed elevations
• Site layout plans
• Roof plans where required
• Location plans for planning submissions
By preparing comprehensive architectural planning drawings, we help reduce delays and increase the likelihood of a successful planning outcome.
Local planning authorities require drawings to meet specific standards before an application can be validated. Our architectural drawings for planning are prepared in accordance with local authority requirements, ensuring that all necessary information is clearly presented.

Yes. We regularly assist clients with the planning application process.
This includes preparing the required drawings, submitting the application and advising on the likelihood of approval. We can also recommend specialist planning consultants if a project requires additional support.
There are several different types of planning applications depending on the project. These can include householder applications, full planning applications, outline applications and change-of-use applications.
Each type is assessed differently by the local planning authority. Choosing the correct application type is an important step in improving the chances of approval.
Yes. A refusal does not necessarily mean a project cannot proceed.
Sometimes a revised design or additional supporting information can address the reasons for refusal. In other cases a planning appeal may be appropriate. We can review the decision and advise on the best course of action.
Minor changes may be possible after approval, but sometimes a further application is required.
It is important that the construction matches the approved drawings. If the design changes significantly without permission it can lead to enforcement action. We can advise on the correct process for making design amendments.
Whether you need planning permission for an extension depends on the size, design and location of the proposed development. Some extensions can be built under permitted development rights, which allow certain types of work to be carried out without submitting a full planning application.
For example, many single-storey rear extensions, loft conversions and small alterations may fall within permitted development limits if they meet specific criteria relating to height, depth, materials and distance from neighbouring properties. These rules are intended to allow homeowners to improve their property while ensuring that the development does not negatively affect surrounding homes.
However, not all extensions qualify as permitted development. Planning permission is usually required if:
• The extension exceeds permitted development size limits
• The property is a flat, maisonette or commercial building
• The building is listed or located within a conservation area
• Permitted development rights have been restricted or removed by the local authority
• The proposed design significantly alters the appearance of the property
Because planning rules can vary depending on the property and location, it is always advisable to confirm the planning status of your project before starting work. In some cases homeowners choose to apply for a Lawful Development Certificate, which provides formal confirmation from the local authority that the extension is permitted development and does not require planning permission.
If you are unsure whether your proposed extension requires planning permission, seeking professional advice early in the process can help avoid delays, additional costs or potential planning enforcement issues.
