With many of us spending more time in the house, home sweet home may be feeling like a bit of a tight squeeze. Whether you're after a garden room, a home office or simply a quiet space to grab a moment's peace, these ingenious tiny homes could offer the ideal solution – and best of all, you can build them yourself. Delivered straight to your door in a handy kit, all you'll need is a little DIY know-how to tackle the ultimate flat-pack project.

What's not to love about a classic A-frame tiny cabin? This sleek design is part of the SOLO series from kit home aficionados Avrame. With floor plans ranging from 141 to 247 square feet, these snug retreats can accommodate up to four people. The flat-pack structural kit for the SOLO 57, which includes materials, blueprints and assembly instructions, will set you back a rather reasonable £8,300 ($10.4k).

Offering worldwide shipping, you'll need to lay your own foundation prior to construction, however, Avrame says that two people with reasonable experience should be able to build the kit cabin themselves. You can also purchase separate kits to add to the main structure, including an interiors package with doors, panelling and framing, plus a selection of exterior finishes that range from French doors to Velux skylights.

Floor plan options vary from a single-room layout, encompassing a kitchenette and sleeping zone, to a more spacious design complete with a kitchen-diner and a separate bedroom. As with any outbuildings you decide to add to your property, it's always a good idea to consult your local planning authority to see if consent is required.

Clad in rustic, warm wood panelling, the Acorn tiny home is a great option for homeowners in need of an extra living space. Manufacturers Backcountry Tiny Homes offer a shell-only option for newbie builders who'd like to try their hand at constructing their own small dwelling. Rather than starting completely from scratch, the kit includes wall, roof and loft framing, exterior siding, windows and doors.

To create the petite tiny home, which covers a 90-square-foot interior and a pocket-sized deck, the shell kit will cost you £13,700 ($17k). The Washington-based company can ship across the United States and they're happy to receive queries regarding deliveries to Canada, as well as destinations further afield.

Inside, large picture windows allow plenty of light to spill into the open-plan living area, which features a compact kitchen, a combined living and sleeping area and a separate bathroom. With no end of customisation options and a smart, space-efficient design, this nifty structure fits a whole lot into a snug space. And best of all, you'll get the satisfaction of building it yourself!

If you're looking for a contemporary garden building that doesn't scrimp on style, look no further than Walden's Modern Loft Cabin. At a relatively generous 240 square feet, it offers the perfect guest annexe or hideaway, with a living space, bathroom, kitchenette and sleeping loft. 

Clad in dramatic blackened wood, you can recreate the streamlined, minimalist home in your own backyard thanks to Walden's handy DIY kit, which you can purchase for £16,000 ($20k). The considered design incorporates large picture windows and an industrial-style metal corrugated roof, as well as provisions for a wood-burning stove to warm the space come winter. 

Delivering across the United States, the kit offers a high standard of finish, with zoned living areas carefully situated for a seamless flow. We love the way the snug kitchen unit is incorporated into the dividing wall, while the cathedral-style vaulted ceiling in the sitting area adds real wow-factor to the compact space. All that's left to do is bribe a few family members or friends to help you build it.

Australian kit home company Tiny Blox offers a large range of affordable, flat-pack structures that you pop up in your garden in no time. With delivery available across Australia, everything you need to construct this stylish design, known as The Alpine, can be purchased for £14,600 ($18k).

The petite interior encompasses 290 square feet of living space, including a kitchen-diner, bedroom and bathroom. While the floor plan lends itself to a self-contained guest annexe, you could easily repurpose it as a remote home office. Outside, there's also a 64-square-foot covered deck – the ideal spot to soak up the sunshine on a lazy afternoon.

Each kit comes complete with steel framework, roof and ceiling structures, sliding glass doors, insulation, cladding, fixtures and fittings, plus interior flooring. Tiny Blox's customisable package also allows you to add on extras to the basic construction package, from kitchen units to eco-toilets, showers and air-con. All you need to do is install a concrete slab foundation or steel footings in your garden and you'll be ready to go when your flat-pack tiny home arrives!

Created by The Backcountry Hut Company, this stylish mini cabin is the ultimate customisable retreat. Designed to blur the lines between indoor and outdoor living, the angular structure covers 185 square feet of interior accommodation, including a sleeping loft. Depending on your needs, multiple units can be combined to create a larger space too.

The shell system can be shipped within the United States and Canada and comes at a starting cost of £21,200 (£26.4k) for System 01. While the design is slightly more detailed than other tiny homes in our round-up, the company says that a few DIY amateurs are more than up to taking on the assembly.

Snug but space-efficient, the pine-clad interior puts every inch of the floor plan to use. Shown here with skylights, a loft bedroom is tucked away in the eaves, while downstairs, built-in cabinets and seating provide functional living spaces for guests.

Kentucky-based Mighty Small Homes offers an array of self-assembly homebuilding kits, however, it's their quaint Cottage model, which has a snug 385-square-foot layout, that caught our eye. The charming design can be customised to include characterful architectural features, including a pitched roof and a loft.

At a cost of £34,500 ($43k) - £41,500 ($51.6k), the kit contains all the tools and materials you need to build the home's exterior shell, roof and interior walls. Additions such as skylights, windows and doors can be thrown in for an extra cost. A perfect beginner's self build project, the company offers international freight shipping, with costs dependent on the location.

Bright, airy and modern, this completed design has more than enough space for guests to reside in comfort or it could even be used as permanent accommodation for adult children or older family members. The Cottage's interior features an open-plan kitchen and living area, while the master bedroom and bathroom sit at the rear. Opting for the loft upgrade adds 96 square feet of additional room that could offer a second bedroom or a cosy nook, plus extra storage in the eaves.

With 230 square feet of accommodation across a compact 100-square-foot footprint, Summerwood's Bala Bunkie is a great way to add extra space to a more compact backyard. One for lovers of the great outdoors, its rustic cedar siding and traditional gabled roof evoke all the charm of a wilderness retreat.

The pre-cut kit will set you back around £7,000 ($8.7k) and includes all the prepared materials you need, from doors and windows to hardware, plus an instructional video. Assembly takes around four days with a novice team of at least two. Best of all, Summerwood says that in general, the cabins can be constructed without a building permit, though you should still check with your local planning department.

Inside, there's enough space for a day bed and a sitting area, while the airy ceilings and overhang create a usable loft space, perfect for sleepovers or summer staycations in the garden. International shipping is available and the company endeavours to deliver to even the most remote locations.

If you’ve ever dreamed of having your own cosy getaway at the end of the garden, look no further than the Writer’s Haven cabin by Jamaica Cottage Shop. Starting from £3,100 ($3.9k) for the frame, this rustic property offers a magical tiny home kit for a bargain price tag.

Framed by a spectacular vaulted ceiling and swathes of windows, the open-plan model offers a single, airy living room. This snug space has no shortage of character and would work perfectly as a quirky home office or hobby room.

Coming in at a compact 132 square feet, this cosy cabin is somewhat smaller than the typical tiny house, though there's enough space inside for a daybed and built-in desk. The property takes a mere 34 hours for two people to construct, with shipping available across the United States and Eastern Canada.

For a little more space than your average garden room, Backcountry Tiny Homes' Basecamp model might fit the bill. An adventurous design spread over three storeys, the 337-square-foot living area is a triumph in tiny craftsmanship. One of the structure's most unique selling points is the rooftop deck – add a few cushions and soft furnishings and you've got yourself the perfect spot for stargazing when night falls.

Available as a DIY shell package, complete with a trailer, framing, siding, roofing, doors and windows, the kit to build this family-sized tiny home costs £28,100 ($35k). The flexible design can be personalised to each buyer's needs – and there's plenty of space to play with. In this completed model, the lounge area can be transformed into a sleeping zone, while the loft above offers extra storage. At the other end of the structure sits a larger loft housing the master bedroom.

As with their Acorn model, shipping is available across the United States, while customers are welcome to inquire about deliveries more further afield. Complete with a trailer and wheels, this ingenious design is fitted out for globetrotting, so there's no reason for this mobile tiny home to stay in your backyard!

If you fancy building your own log cabin, look no further than the Timbertrail kit from Coventry Log Homes. Featuring a rustic log construction and a quaint front porch, the charming design offers an easy to assemble woodland retreat. Available from £25,900 ($32.1k), the package includes everything you need, from exterior and interior walls to a metal roof, windows and doors.

On the more generous side of small with a 392-square-foot floor plan, the cabin includes a living area, bedroom and bathroom, along with a loft space that could be used as extra sleeping accommodation. According to the company, the simple wood structure can be created in three to four weekends with the help of a few DIY-savvy friends.

Interior finishes are pared-back and minimalist, with plenty of exposed pine used throughout. Shipping the tiny home kit across the US's Eastern Time Zone is charged at $1. Buyers in other areas should contact the New Hampshire-based company directly for delivery information.

Developed by award-winning architects Studio Bark, U-Build was created to simplify building construction and empower ordinary homeowners to get involved with the process. A great way for DIY novices to create their own garden rooms, the structure's parts are precision-cut and delivered to your door.

For a unit made from spruce, measuring around 107 square feet, you'd be looking at just over £10,000 ($12.4k) for the kit, which includes the structural elements, windows, doors, roof lights, insulation and membranes, plus detailed instructions. The U-Build system can be delivered across the UK, while aspiring builders from further afield should get in touch with the company directly for shipping queries.

This completed garden room in East London is used as an additional family space and art studio, as well as for storage. A large picture window bathes the plywood-clad space in light, while clever skylights set into the ceiling banish dingy corners. U-Build says its construction requires surprisingly few tools – as a guide, you'll need a minimum toolkit of a rubber mallet and a battery-powered drill.

Arched Cabins is a family-owned business that produces cost-effective prefabricated homes. Sustainable and quick to assemble, these rustic retreats have become extremely popular among tiny house communities. Featuring distinctive arched roofs, designs come in a number of sizes ranging from an eight-foot-wide single-room cabin to a large family-sized model with up to three bedrooms.

For a 144-square-foot wide arched cabin, the DIY kit comes in at just over £3,000 ($3.8k), not including delivery. Inside, there's enough room to comfortably fit a bedroom, kitchen and bathroom, with larger models accommodating a sleeping loft in the eaves.

The clever flat-pack cabin kit arrives with everything you need to construct your rustic escape, including a user-friendly instruction manual that will guide you through the build process. While the Texas-based company primarily ships within the US, they invite customers to reach out about international shipping.

This miniature marvel is pretty as a picture, with its gabled roof, ornate windows and architectural detailing. A multipurpose garden room, Summerwood's Copper Creek Shed can accommodate everything from an art studio to a yoga retreat or even your very own home bar. 

Available in a range of finishes, the elegant 96-square-foot structure would make a stunning addition to a landscaped garden or pristine patio. The pre-cut kit, which can be shipped internationally, has a price tag of just over £4,000 ($5k), while optional extras, such as the quaint casement windows, can be added on to the package.

These homeowners have personalised their tiny house with durable siding on the exterior and traditional finishes inside. Used as a refined garden room, we love the addition of the regal cornicing and the gorgeous stained-glass door panels!
