What we help with
From a first idea to planning-ready drawings
Whatever stage you're at, there's a service to suit. Design only — we don't carry out the building work, which keeps our advice focused on getting your design right.
Plain English
Not sure what drawings you need?
Most projects involve one or two different sets of drawings, prepared at different stages. Here's the quick version — and a guide for each.
Planning drawings
Show the council what you want to build and how it looks. Needed when your project requires planning permission.
Do I need planning permission?Building-regulations drawings
Show how the work is built and meets safety and energy standards. Needed for almost all building work.
Do I need building regs?Builder-quote drawings
Let several builders price the same scope, so you compare like with like and the build matches what you agreed.
What drawings do builders need?Local knowledge
Local design knowledge across Wirral
Working right across Wirral, we know the local housing and the planning context that shapes what's achievable — and where to take extra care.
- Period homes in Wallasey, Birkenhead and Oxton that reward a sympathetic design approach.
- Conservation sensitivity around Port Sunlight, Oxton and parts of Bebington — confirmed with Wirral Council for your address.
- Coastal & sloping sites in Heswall, West Kirby and Hoylake, designed around light, levels and outlook.
- Family extensions across Bromborough, Moreton, Upton and Greasby that add real, everyday space.

Project examples & design visuals
We keep these two things separate and honest: illustrative concept visualisations now, and real project case studies as they're ready.
Concept visualisations
AI before/after examples that show the kind of transformation good design makes possible. Clearly labelled as illustrative — not completed projects.
Real project case studies
Real SC Design Wirral projects — home extensions and remodels across Wirral, plus commercial and conversion work — each with the brief, the design response and the drawings prepared.

Frequently asked questions
Yes — that is often the best time to involve us. We help you explore what is possible and shape the brief, turning a rough idea into a clear architectural design you feel confident about.
Please do. A few photos and a short description of what you're hoping to achieve let us give you an honest first view before any commitment. You can send them by WhatsApp, email or the contact form.
Usually quickly. Once we've seen a few photos and your postcode, we aim to come back to you with an honest first view of the likely route — there's no obligation.
It depends on the size, position and type of your project, and on your property. Many home projects fall under permitted development, but plenty do not. We advise on the likely route and prepare the drawings you need — always confirmed with your local planning authority.
We prepare the drawings and support the submission. The application is made in your name (or your builder's), and we guide you through the process and any requested changes.
Permitted development rights let you build certain things without a full planning application, within strict limits. Whether your project qualifies depends on its size, position and your property — and some homes (flats, conservation areas, Article 4 areas) have reduced or no rights.

“Used Sean for the first time after a recommendation from a close friend and I couldn't be happier. Honest, hard working lad who has made our build and design smooth and effortless. Will be recommending him to everyone. Thank you so much Sean.”

“I used Sean a couple of years ago for a small scale rear extension. His drawings are extremely readable so for me as a builder it made the job run smoothly and more important the ordering of materials was clear. Since then I always use Sean for small scale and large scale projects.”

“Would highly recommend. From initial briefing to completion of the drawing pack Sean was outstanding with his knowledge. Would use again in a heartbeat.”
