Expand Your Living Or Storage Space with An Outbuilding
When it comes to extending your home, building a garden room, home office, or garage can be one of the smartest and most versatile investments you make.
Outbuildings offer incredible flexibility, whether you need a peaceful home office, a stylish guest suite, a gym, a creative studio, or simply more storage. Designed properly, they don’t just add valuable space to your lifestyle; they also add significant value to your property.
Unlike traditional extensions, outbuildings are often quicker to construct, more cost-effective, and, in many cases, can be built without the need for full planning permission. They allow you to make the most of underused areas of your garden or land, creating a beautiful, functional space that's separate from your main home.
At Plans4Extensions, we design outbuildings that perfectly complement your property and meet your needs, whether you’re looking to create a quiet retreat, a practical workspace, or even a future-proofed annexe for family living.
Outbuilding Types
01. Garden Rooms
Unlock the Potential of Your Garden with a Garden Room
A garden room is one of the most versatile and rewarding ways to extend your living space—without the disruption of a major home renovation.
Whether you dream of a peaceful home office, a bright and airy gym, an inspiring art studio, a music room, a relaxing guest suite, or even a dedicated entertainment space, a beautifully designed garden room can make it happen. Offering year-round comfort and style, a garden room allows you to create a space that feels like an extension of your home, while giving you valuable separation and privacy.
Garden rooms are often quicker to build, require less disruption to your home, and in many cases can be created without the need for full planning permission. They are incredibly energy-efficient, thoughtfully designed, and tailored to suit your lifestyle.
Beyond the day-to-day benefits, a well-designed garden room can significantly enhance the value of your property, making it a smart investment for the future.
At Plans4Extensions, we work closely with you to design a bespoke garden room that complements your home, your garden, and your aspirations.


02. Single or Double Garage
A Garage: Practical, Valuable, and More Space for Your Home
Adding a garage to your home isn’t just about somewhere to park the car, it’s an investment that brings flexibility, security, and real value to your property.
A well-designed garage offers so much more than shelter for your vehicle. It provides secure storage for tools, bikes, garden equipment, or even seasonal belongings. It can double as a home workshop, a hobby space, a utility room, or even be future-proofed for conversion into a home office or annexe down the line.
A garage also enhances the kerb appeal of your property and can significantly increase resale value. Homes with additional, secure parking or extra storage are highly attractive to future buyers, making a garage a smart choice whether you plan to stay long-term or eventually sell.
In many cases, garages can be built with minimal disruption to your existing home and, depending on size and location, may not require full planning permission, making the process quicker and more cost-effective than you might expect.
At Plans4Extensions, we design garages that are functional, stylish, and tailored to fit both your needs and your property perfectly.
03. Garage Extension
Build Above Your Garage to Unlock Hidden Potential
If you have an existing detached garage, extending upwards is possible and is a smart way to add valuable living space without losing any garden or driveway area.
An over-garage extension can create a stunning home office, or playroom or a games room, all while enhancing the overall value and functionality of your home.
At Plans4Extensions, we specialise in designing seamless over-garage extensions that blend perfectly with your property's existing style, giving you the extra space you need without the cost and complexity of moving.
