London's Bert and May Group recently launched a series of clever prefabricated box homes that take as little as one day to set up. The design firm has created four different versions of its prefabricated Big Box home, ranging from a 46-sq m (495-sq ft), two-bedroom family home, down to a 7.7-sq m (82-sq ft) tiny home. Created in collaboration with local architectural studio Box 9 Design and taking 14 weeks to manufacture, the fully-functional tiny dwellings boast a rustic appeal, eco-friendly materials, structural insulation and a green roof.

The Bert and May Group was inspired to design the Big Box home from its firm belief that everyone should have access to an affordable and sustainable home without compromising on space or quality. The design of the Big Box home therefore has a strong focus on storage space, efficient heating, insulation, abundance of natural light and good air flow. Furthermore, each home has been built using reclaimed and sustainable materials, such as weathered barn oak for the exterior and interior walls, reclaimed timber for the flooring, double glazed aluminum doors and toughened glass windows.

Made with a steel frame and strong wood cladding, each Big Box home is straightforward to install and takes as little as day to get the job done. The prefab homes are also expected to withstand most weather conditions and come with a 10 year structural guarantee. The home's green roof helps to retain interior heat during the winter months while also keeping the home cool in the summer. Buyers will also be given the choice to add an exterior edible garden wall and a solar thermal energy system with air source heat pump to their home.

The Big Box homes come complete with either a Luxury Fit or Premium Luxury Fit. The former includes a 43-inch Sony TV, Sonos music system with ceiling speakers, polished chrome and brushed nickel fittings in the bathroom and kitchen, while the latter fit-out includes a 49-inch Sony TV, Autonomics Mirage music system with Amina invisible ceiling speakers, custom home automation system with single handset or iPad control for the TV, music, lighting and heating, and gun metal and aged brass-ware fittings in the bathroom and kitchen. Each Big Box home comes as standard with Nest learning thermostats and smoke detector, Luxul Desk router, Water Monopoly sanitary-ware and Factory Lux industrial lighting.

Here's a look at the four different tiny homes on offer:

Two Bedroom Big Box

The two bedroom Big Box squeezes into an area of 46 sqm (495 sq ft) and features an European wall kitchen and open plan dining and living area that opens up onto the outdoor terrace. The tiny home also includes a central bathroom with retractable wall for showering in the open, a single bedroom or study and private master bedroom positioned at the end of the house.

  • Exterior: 4.2 x 20 x 3.4 m (13.8 x 65.6 x 11 ft) (WxLxH), including terrace
  • Interior: 4.2 x 17.2 x 2.4 m (13.8 x 56 x 7.9 ft) (WxLxH)
  • Price: £175,000 (US$269,000) for the Luxury Fit and £225,000 (US$345,850) for Premium Luxury Fit

One Bedroom Big Box

The one bedroom Big Box home is practically identical to the two bedroom version, but has slightly lower exterior height and doesn't have the smaller second bedroom. This provides room for a more spacious open plan living and dining area and master bedroom as a result.

  • Exterior: 4.2 x 20 x 3 m (13.8 x 65.6 x 9.8 ft) (W x L x H) - including terrace
  • Interior: 4.2 x 17.2 x 2.4 m (13.8 x 56.4 x 7.9 ft) (W x L x H)
  • Price: £150,000 (US$230,500) for the Luxury Fit and £200,000 (US$307,300) for the Premium Luxury Fit

Little Box

The Little Box is a 19-sq m (205-sq ft), one-bedroom, self-contained studio home with separate bathroom. The home is fitted with large windows and sliding doors which open out to the surrounding landscape. Its layout is not that different to a large hotel suite and, being inspired by the seaside, the interior and exterior aesthetic of this home is lighter than the larger versions. Little Box could be ideal as a great little country escape, beach side retreat, backyard guest house or tiny house for a teenager or young adult.

  • Exterior: 3.4 x 7.5 x 3.4 m (11 x 24.6 x 11 ft) (W x L x H)
  • Interior: 2.8 x 6.9 x 2.4 m (9.2 x 22.6 x 7.9 ft) (W x L x H)
  • Price: £70,000 (US$107,550) for the Luxury Fit and £120,000 (US$184,400) for the Premium Luxury Fit

Teeny Box

The 7.7-sq m (82-sq ft) Teeny Box is a an urban-inspired private open space unit. It is a single room shelter without a bathroom, kitchen or amenities. The Teeny Box could fit the bill as a quiet tiny retreat, backyard home office, guest room or art studio.

  • Exterior: 3.4 x 3.4 x 3.4 m (11 x 11 x 11 ft)
  • Interior: 2.8 x 2.8 x 2.4 m (9.2 x 9.2 x 7.9 ft) (W x L x H)
  • Price: £25,000 (US$38,400) for the Luxury Fit and £50,000 (US$76,800) for Premium Luxury Fit

All of the Bert and May Big Boxes can come fully furnished, with final prices on request.
