Site layout drawings
These documents are tailored to meet planning authority requirements and help builders and engineers understand your project clearly. Whether you're submitting for planning approval or starting construction, we ensure everything is covered with precision.
3D Visualisations & Concept Design
Our 3D architectural renderings give you a realistic view of your project before work begins. Whether you're exploring internal layouts or visualising your extension in the context of your home, our visualisations help:

Frequently Asked Questions
Do I need planning permission for my project?
Not always. Many home extensions fall under permitted development. We’ll review your plans and advise whether a full application is needed.
How long does it take to get drawings?
Typically, architectural drawings take 1–2 weeks to complete after the initial site survey. This can vary depending on the complexity of the design.
What’s the difference between planning drawings and building regulation drawings?
Planning drawings are used for gaining planning permission, while building regulation drawings include technical details for construction and compliance with building control.
Can you help if my application is refused?
Yes — we can revise your design, address any objections, and re-submit the application on your behalf.
