Extension Plans and Planning: Expert Plan and Drawings Services for House Extensions and Home Extension Projects

Need Extension Plans Drawn? That’s What We Do.

100% Fixed Fee House Extension Plans With No Hidden Charges

We get asked all the time — “how much do extension plans cost?” or “do I need an architect, or just someone to draw it up?”

Here’s the truth: you don’t need a glossy design firm or a bloke with a biro. You need an experienced professional who knows how to design your extension properly, draw it up accurately, and get it through planning without all the faff.

That’s exactly what we do.

With nearly 30 years in architectural design and 1,000+ projects under our belt, we’ve helped homeowners, builders, and developers turn ideas into solid, buildable plans — the kind councils approve and builders respect.

So whether you’re searching for:

Extension drawings
Plans drawn up for your extension
Architectural plans at a fair price
Or just someone who knows how to get your project moving…

We’ll survey, design, draw, and submit — and we’ll give you a fixed, all-in price.

Prices start at £595.00 for planning drawings for a single storey extension.
Building regs plans? That’s £695.00.
Want both done in one hit? Just £995.00.

No hidden costs. No stress. Just accurate plans, done properly.

We Make Measuring Effortless

No tape measures. No handheld lasers. We use LiDAR scanning technology — the same used in self-driving cars — to capture your home with millimetre precision. That means zero guesswork, zero stress, and a perfect foundation for your plans.

We create your Extension Plans

We turn your scan into ultra-precise, council-ready drawings — typically within 10 working days. The level of accuracy we provide is unrivalled by most traditional methods.

We Handle Everything Until You’re Approved

Our agents manage the entire application process — from submission to decision. We deal with the council on your behalf, so you don’t have to chase updates, respond to queries, or deal with any of the stress.

Kevin is flexible, listens to what has been asked. He is knowlegeable about ideas and suggestions and gives you leave options. The plans were clear to read and were done to a professional high standard. If you live in Essex and want a good value price then Kevin is the man to contact. My plans were submitted on Monday as the price is going out and they were done in a timely manner.

What Are Extension Plans and Why Do They Matter?

Extension plans are the blueprint for your house extension, transforming your vision into a practical design. Quality planning ensures your extension fits your needs and property, addressing key services like electrics and plumbing. Thorough plans factor in building regulations, so your home extension meets every requirement.

Professional extension services streamline the whole design process, saving you time and money. Whether you’re just starting or refining existing ideas, tailored extension plans turn potential into reality. Trust experts in building planning to deliver a house extension that blends seamlessly, giving you peace of mind and a beautifully designed, functional new space.

Understanding the Essentials for Seamless House Extensions

Getting a smooth extension for your home starts with understanding the essentials. Whether you’re after a bigger house or more space, seamless planning is key for building that extra room without headaches. Good extension designers bring specialist services, creating practical, tailored extension plans that fit your vision and the council’s rules.

With thorough planning, extensions feel like part of the house, not an afterthought. The right building approach means everything flows – from initial idea to final build. With reliable extension plans, quality extension services, and expert guidance, your extension project is a breeze, not a battle.
