Tiny house container : living in a shipping container
From the garden studio of 20 feet to the family home of three modules, the shipping container has become a real alternative for compact, modern and economical housing. What you need to know before starting: actual prices, standard plans, regulatory points, pitfalls to avoid.
Three standard plans

1 × 40 feet high cube. 28 m² gross, 23-24 m² habitable after insulation. Living room + kitchenette + bathroom + sleeping area. Ideal for single person, holiday cottage, residential office.
£14,057 – £43,313
T2 two modules
2 × 40 feet HC joined together. 56 m² gross, 48-50 m² habitable. Living room + kitchen + bedroom + bathroom. Format for couples, second home, Airbnb rental.
£27,612 – £74,813
Family Home 3-4 Modules
3 or 4 × 40 ft HC, potentially on two levels. 80 to 120 m² of living space. Living room, kitchen, 2-3 bedrooms, 2 bathrooms. Main family residence.
£47,693 – £141,750
The 5 Key Decisions for Your Project
- Number of Modules. Start with the targeted living space area, multiply by 1.2 (for insulation loss), then divide by 28 to determine the number of 40 ft HC containers needed. Allow extra space for circulation.
- Brand New or One-Trip Containers. For housing, never use Grade B or C used containers. Brand new for a perfect showcase, one-trip to save 15-20%.
- Interior or Exterior Insulation. Interior: faster and cheaper, but thermal bridges must be dealt with. Exterior: better thermal performance, more expensive, needs cladding. Exterior insulation is usually preferred for a permanent home.
- Foundation Type. Concrete slabs (easy, demountable), perimeter longline (balance), concrete slab (most stable, but fixed habitation). Choose according to your tolerance for future relocation.
- Architect required or not. Strongly recommended from two modules, for structural checks and a solid application. Planning and building-control requirements differ between the four UK nations: confirm the drawings, structural design and professional involvement needed, and agree the scope and fees in writing.
Frequently Asked Questions
Can one really live in a shipping container on a daily basis?
Yes, provided you choose the right format and do not skimp on insulation. A 40ft high cube offers 28 m² of floor space and 2.69 m of internal height before insulation, the equivalent of a studio flat. For a couple, two modules side by side (56 m² gross) make a comfortable one-bedroom home.
How much does a tiny house shipping container cost?
Indicatively, a single 40ft high cube converted into a studio (23–24 m² of living space) costs £14,057 – £43,313 turnkey; a two-module home (48–50 m²) £27,612 – £74,813; a family home of 3–4 modules (80–120 m²) £47,693 – £141,750. Excluding land, connections (£5,250 – £15,750), taxes and any fees. Compare offers with comparable equipment and delivery.
Is this really a 'tiny house'?
Strictly speaking, a tiny house is a mobile home on a trailer, usually under 20 m², so a 28 m² container home is more than a tiny house: it is better described as a minimalist home. For a true tiny house on wheels, a 20ft container can be mounted on a flatbed trailer, within the weight and size limits that apply on the road; a standard container is lower than a high cube.
What regulations apply to a tiny house shipping container?
The rules for any home apply. In the UK, planning permission and building regulations (a building warrant in Scotland) are separate checks, with different systems in England, Wales, Scotland and Northern Ireland. A container on wheels must also meet road requirements, and mobility does not create a general exemption from planning permission. Plan the water, drainage and electricity connections or an off-grid system, and confirm the project’s status with the local authority.
Is insulation really the critical point?
Yes. An uninsulated container becomes an oven in summer (interior at 45 °C with exterior temperature of 30 °C) and a freezer in winter. For habitation, minimum requirement: 80 mm of sprayed polyurethane to walls and ceiling, 50 mm under the floor. Budget £4,725 – £8,400 for a 40 ft HC. Never insulate 'internally with glass wool panels' without thermal bridge break — classic mistake that generates condensation and mould.
Can a tiny house container be moved once installed?
Yes, if it is placed on concrete blocks or sleepers (not on a full slab). Dismantle connections, load by crane onto flatbed truck, transport, reinstall. Cost: £1,575 – £4,200 per trip for one module. For multiple assembled modules, the assembly must be disassembled, which becomes more complex. Plan from conception if mobility is a criterion.
