Prepared with real technical understanding
Prepared with real technical understanding
Even though this service provides planning drawings only, you benefit from our knowledge of building regulations and construction techniques. We prepare your plans with the same care and technical awareness we apply to full working drawings, so your project can progress smoothly to the next stage if you decide to continue. In some cases, and depending on the proposal, we can also assist with the next stages of the design process if you require more detailed drawings later on.
We go the extra mile

We treat every project with the same attention to detail we would expect for our own homes. This means clear drawings, thoughtful layouts and a genuine commitment to getting your application right.
We do not leave you on your own
We do not leave you on your own
Most online services stop at producing drawings and leave clients to deal with the planning process themselves. We do not work that way. If you wish, we can manage the entire planning application on your behalf, including submission, liaison with the council and handling any queries that arise. We do not leave you on your own.

Transparent, Fixed Fee Planning Drawings
Transparent, Fixed Fee Planning Drawings
We believe clients deserve complete clarity from the very beginning. Our online planning drawings start from a fixed fee of £465 for the most basic projects, but every home and every proposal is slightly different. A small extension, a dropped kerb, a fence alteration or a solar installation can each require different drawings, checks and supporting information. Publishing a single price for all projects would either mislead clients or force us to add hidden extras later, which is something we never do.
To help you understand what to expect, here are typical prices for the most common types of small domestic projects:
Extensions
Extensions
• Small extensions with simple footprints
• Typical price: £696 to £950
Garage Conversions & Outbuildings
• Garage conversions
• Garage conversions
• Outbuildings and garden rooms
• Typical price: £525 to £700
Other Common Projects
Other Common Projects
• Dropped kerbs
• Enclosing existing carports
• Solar PV installations
• ASHP installations
• External wall insulation (EWI)
• Porches, canopies and minor additions
• Permitted Development Certificates (LDCs)
• Typical price: £465 to £700
These figures are a helpful guide, but the exact fee always depends on the details of your proposal.
We therefore provide a free, no‑obligation quote tailored to your project. Your quote is clear, easy to understand and includes everything you need to budget properly. We set out our fee with no hidden charges, and we also include any statutory fees or third‑party costs that may apply. The aim is to give you the most accurate and complete understanding of the total cost of your project from the very beginning, so you can make an informed decision with confidence.

Frequently Asked Questions
Frequently Asked Questions
What information do I need to provide?
What information do I need to provide?
For most applications you probably won’t need to provide anything at all. We use OS Maps, which are included in our fee, to obtain accurate site dimensions, check boundaries and understand the layout of your property. We also review previous planning applications for your address and, where appropriate, we can estimate measurements based on standard construction proportions. Depending on the type of application, we may occasionally ask for photos of the rear or side of the property, a simple sketch of the internal layout, confirmation of a key measurement or a quick check of the boundary line against your title deeds, but in many cases none of this is required. The process is designed to be straightforward and to minimise the amount of information you need to provide.
How accurate are the drawings without a site visit?
How accurate are the drawings without a site visit?
Our drawings are fairly accurate and more than sufficient for planning purposes. We obtain most of the key information from OS measurements, previous planning applications and other reliable mapping data, all of which allow us to produce precise plans without a site visit. In some cases we may need to confirm a specific measurement if it is important for the application, but this is usually quick and straightforward. Overall, the level of accuracy is exactly what councils expect for planning submissions, and more than adequate for the type of applications we prepare.
What is included in the fixed fee?
What is included in the fixed fee?
Your fixed fee includes a full set of existing and proposed planning drawings prepared at a scale of 1:100, including plans and elevations as required for your specific application. Where certain information is unnecessary (for example first floor layouts or the internal arrangement of the house when the proposal relates only to an outbuilding, porch or other external change) we simply omit it to keep the submission clear and relevant. You also receive a scaled Site Plan and a basic planning design statement to support the application. If you choose for us to manage the application, we will prepare and submit it on your behalf and communicate with the council throughout the process [planning fees and Planning Portal fees are not included in our price].
How long does it take?
How long does it take?
Most drawing packages are completed within three to five days, with simpler applications sometimes ready in one to two days and more detailed extensions taking up to two weeks. Once the drawings are finished, the timescale for the application itself depends entirely on the council, as each local authority has its own validation times and decision periods.
Can you submit the planning application for me?
Can you submit the planning application for me?
Yes. We can prepare and submit the full application on your behalf if you prefer.
What if I’m not sure what permission I need?
What if I’m not sure what permission I need?
If you are not sure what type of permission you need, we will advise you when you request your quote. We review your proposal, check the relevant planning rules and confirm whether it should be submitted as Planning Permission or as a Lawful Development Certificate. If we believe it falls under permitted development, we will quote for an LDC instead, as this is usually the most cost‑effective option and can save you money.
Is this valid for listed buildings or conservation areas?
Is this valid for listed buildings or conservation areas?
Most of the time yes, our drawings are suitable for applications in conservation areas and for listed buildings, although the planning department may require additional documents such as a heritage statement or a more detailed design justification depending on the sensitivity of the site. We can often provide these documents for an additional fee if the requirements are straightforward, but in some cases the council may ask for input from other specialists such as bat surveys, glare assessments or similar technical reports.
