UK rules permit certain building works to proceed without the need for full planning permission, thanks to permitted development rights. These rights are a key aspect of UK planning law, allowing homeowners to undertake specific types of extensions and alterations without applying for full planning permission, as long as they adhere to strict rules and limits.
While planning permission evaluates whether the development is acceptable in principle, permitted development focuses on pre-approved criteria such as size, height, position, and use. If your project remains within these guidelines, it can typically move forward without requiring a full planning application.
Common projects that may qualify under permitted development rights include architectural drawings for single-storey rear extensions, loft conversions and dormers, garage conversions, side extensions (subject to limits), roof alterations (like Velux or rooflights), and internal alterations (non-structural).
However, not all homes are eligible. Flats, maisonettes, listed buildings, and properties in conservation areas may face restricted or entirely removed permitted development rights.
Even though full planning permission may not be required, accurate architectural drawings are essential to demonstrate that your project complies with permitted development rights and to avoid future issues.
Permitted development drawings support:
✅ Assessment of PD eligibility before you build
✅ Clear confirmation that size, height, and location limits are met
✅ Lawful Development Certificate (LDC) applications
✅ Builder clarity and accurate pricing
✅ Mortgage, solicitor, and future sale requirements
Without proper architectural drawings and checks, homeowners risk:
Breaching permitted development rights unknowingly
Enforcement action from the council
Problems selling or refinancing the property
Costly redesigns or retrospective applications
Planning Permission
Is this development allowed in principle?
Design and appearance
Neighbour and street impact
Policy compliance
Permitted Development Rights
Does the proposal stay within pre-approved limits?
Size, height and volume
Position relative to boundaries
Use and roof alterations
Key Differences
✅ Planning permission decides if you can build
✅ Permitted development rights determine whether permission is required
Permitted development rights typically control various aspects, including maximum extension depth and height, roof volume increases for loft conversions, and the required distance from boundaries. Additionally, these rules outline the use of materials to ensure a similar appearance, the position of structures relative to highways, and the property's use as a single dwelling. For any alterations that exceed these limits, full planning permission will usually be required, often accompanied by architectural drawings.
Many projects require architectural drawings, and while permitted development rights may allow you to bypass planning permission, Building Regulations still apply. Approval for Building Regulations is typically necessary before construction begins.

A Lawful Development Certificate (LDC) is official council confirmation that your project is lawful and did not require planning permission. Obtaining an LDC is essential for demonstrating compliance with permitted development rights, and it serves as: ✅ Legal proof of compliance ✅ Commonly requested by solicitors during sales ✅ Required by many mortgage lenders ✅ Strongly recommended for peace of mind. To apply for an LDC, permitted development drawings are a core requirement.
We design the architectural drawings to stay within permitted development rights, ensuring:
Size and height compliance
Roof and dormer restrictions are met
Position and use rules are followed
Any risks are flagged early before planning permission drawings are finalized.
We produce a comprehensive pack of architectural drawings suitable for: Lawful Development Certificate applications, builder reference, and property records, ensuring compliance with permitted development rights and planning permission requirements.
You can:
Submit the LDC application yourself, or
Ask AS Global to assist you with the architectural drawings and guide you through the process of obtaining planning permission under your permitted development rights.
We remain available to answer any council queries if needed.

Yes — in most cases. Planning permission confirms the proposal is acceptable in principle (appearance, impact, policy compliance), but Building Regulations approval confirms the design is technically compliant and buildable.*
Building Regulations drawings are typically required for:
Even where planning isn’t required (e.g. Permitted Development), Building Regulations often still apply.
Yes. AS Global produces Building Control-ready technical drawing packages suitable for submission to:
Our drawing packs are prepared in a clear “Full Plans” format and typically include:
This helps reduce back-and-forth queries and supports a smoother approval route.
Structural calculations are not always required, but they are commonly needed where the project involves structural change, including:
Where required, we can coordinate with a structural engineer so that:
Our Building Regulations drawings are prepared to provide practical construction guidance and demonstrate compliance. Depending on project scope, packs can include:
These drawings are far more detailed than planning drawings and are designed to be used by builders n site.
Timescales vary depending on the Building Control provider and the submission route, but typically:
We strongly recommend Full Plans for most projects, as it gives greater certainty before construction starts and reduces risk of costly changes later.
Yes — very often. Permitted Development only relates to planning permission, not construction compliance.
Even if planning is not required, Building Regulations may still apply to:
If you’re unsure, AS Global can advise you before you start.
Yes — in many cases we can work from:
However, for Building Regulations accuracy we may also require:
If the information is limited, we’ll confirm what is missing and the best way to proceed.

If queries are raised, AS Global can assist with amendments and responses to keep the approval process moving quickly.
Yes — this is one of the biggest benefits of a Building Regulations package.
Building Regulations drawings reduce uncertainty by clearly defining:
This typically results in:
✅ more accurate builder quotes
✅ fewer “unknowns” and provisional sums
✅ reduced risk of cost increases during the build
Yes — our drawing packages are prepared with the key Approved Documents in mind, including:
The exact requirements vary by project type and layout, and we tailor notes accordingly.
