Compact prefab houses up to 60 m²

The roof extends over a covered terrace that adds half a house again (21.6 m²): in a house this size, it is the living room for the good months.

It is a solid-log kit: floor, walls, roof structure and timber windows and doors. Per square metre it is one of the pricier kits (31% above the median for timber kits, across 132 houses from 8 manufacturers), and you can see what the extra pays for: the joinery, the VAT and delivery to the plot on mainland Spain, which a kit does not take for granted. The rest is up to you: the roof finish, insulation, assembly, foundations and services. For a couple or a small family with someone to finish it.

It is the only one on this page with three bedrooms, all on one floor next to the living room with the kitchen and the bathroom, so the rooms are small.

It is a kit of tongue-and-groove spruce planks to assemble on the plot: you get the walls, the roof boarding, the doors and the windows, with the screws and the instructions. Per square metre it is one of the cheap kits (49% below the median for timber kits, across 132 houses from 8 manufacturers), with VAT and delivery to mainland Spain included, and what it leaves out explains why: the roof finish, the flooring, the unloading, the assembly, the slab and all the services. The brand pitches it as a country cottage, guest house or holiday let, not for an urban plot with a building project.

Its kit is cheap per square metre (39% below the median for timber kits, across 132 houses from 8 manufacturers), although Avrame does not make clear whether that price includes the windows and the roof covering.

It is an A-frame: the roof comes down to the ground on both sides and forms the walls. Downstairs there is room for the living room with a galley kitchen, the bathroom and the bedroom, and upstairs an open loft for sleeping, working or storage; its floor area counts that loft. It arrives as pre-cut pieces from Estonia, and insulation, foundations, assembly and all the services are sorted out on site. For a mountain retreat, a guest house or a rural rental, if you see yourself building it or have carpenters nearby.

It is one of the few Avrame models already built in Spain: its project list includes a Duo 100 put up here in 2019.

Its floor area counts the loft: the ground floor is smaller (about 35 m²) and holds the living room with the kitchen, a closed bedroom and the bathroom. Per square metre the kit is cheap (26% below the median for timber kits, across 132 houses from 8 manufacturers), because you pay for the structure and the envelope: no VAT, no delivery from Estonia and no insulation, assembly or services. For a couple or a family of three ready to get involved in the build.

It is the only house on this page that travels folded and unfolds on the plot in a few hours, with delivery and installation included in the price.

It arrives finished: cross-laminated timber with wood-fibre insulation, bathroom and kitchen fitted, lighting, a fuse box and the water and drainage connections ready to hook up. What you save is building work and waiting on the plot; what it costs you have to ask, because it does not publish a price. The Latvian brand pitches it for living, working or renting, and it suits you if you want something habitable without getting into building work.

The living room and kitchen take up more than half the house (21.9 m²) and open onto a glass wall.

It is made by the Latvian firm Evermod and sold from Portugal by Inove Urban, which says it delivers anywhere in Europe. It arrives finished from the factory, with doors, windows and finishes, and delivery and foundations are extra. Evermod asks more for it on its own website than Inove Urban does: get the price confirmed in writing. Besides the living room, it has a good-sized bedroom (12.2 m²), the bathroom and a hallway. For one or two people: a first home, a studio or a rental.

It is the only house on this page with solar panels and a battery in the entry price, so it gives you power on a plot with no grid connection.

It is a one-piece module set down finished on ground already prepared. It is narrow (3 m wide on the outside), so everything goes in a row: the bathroom at one end, the kitchen and dining area in the middle and the sleeping area at the back, for two or, squeezed, four. Per square metre it is expensive (74% above the median for turnkey timber houses, across 47 houses from 10 manufacturers): you pay for self-sufficiency in very few square metres.

It is the only house on this page with two closed bedrooms that is sold finished and with a published price.

It is made by the Latvian firm Evermod and sold from Portugal by Inove Urban, which says it delivers anywhere in Europe. It arrives finished from the factory, with doors, windows and finishes, and delivery and foundations are extra. At Inove Urban's price, per square metre it costs what is normal for timber houses sold finished with assembly extra (the median is 1,176 €/m², across 56 houses from 10 manufacturers), but Evermod asks more for it on its own website: get the price confirmed in writing. The second bedroom is not a box room (10.3 m², and the main one 12.5), so it works for a couple with a child, for someone who needs a home office or for a rental used in winter too.
