LocationAlbion, MI, United States

This 1100 sqft modular house design is composed of two intersecting diagonal axes centered around social area - dining room as a meeting place. One axis incorporates the bedrooms, the other axis includes the living room and public entry hall. The design consists of two modules and uses new modular technology - Kullman Frame System (KFS), which allows build modular homes of prefabricated steel hollow tube frames. This prefabricated system has capacity to achieve 12 stories height and uses patented connection technology that speeds the overall construction process and minimizes field finishing.

Description by architects

Koby Cottage was designed to accommodate families visiting their children attending a boarding school for troubled teens. Surrounded by nature, it provides a peaceful, private domestic setting for reuniting families.

The eleven hundred square foot cottage has an X-shaped plan formed by joining two prefabricated steel modules. One wing is for parents, the other for their child. A dining table is situated where the two wings cross to create a place for meeting, discussion and to express family bonds. The structure is raised above the ground and the space between the modules is sheathed with glass to show the landscape as continuous and nature as enveloping.

Koby is a prototype constructed using the KFS (Kullman Frame System), an extremely strong and efficient modular space frame consisting of hollow tubular steel that allows for large cantilevers and window openings. The structural system was developed for the construction of multi-story modular buildings. Its tubular steel space frame has the unique capacity to achieve heights of twelve stories using patented connections that minimize field finishing and speed the overall construction process. The cottage features a high level of craftsmanship and detail as well as number of high performance components.

Prefab SIP Panel House

Built with Structural Insulated Panels (SIP), this prefab SIP panel house is conceived as an attempt to achieve a maximum optimization of dimensional and structural qualities of this construction material. This modular house was built in 10 days with 40 split-level panels (21 cm x 488 cm x 122 cm) and 71 wall panels (11.4 cm x 244 cm x 122 cm). The SIP panels exposed on the facade are fashioned as terraces on the third and second floors.

This modular prefab elevated home on stilts is composed entirely of ready-made components and off-site manufactured elements, assembled in less than six weeks. The install process begins with off-site manufactured ceiling and floor panels. They distribute cold and hot water, radiant heating, waste water, electricity and ventilation through the building. Fully integrated mechanical room and bathroom modules are lifted into planned position. Wall panels containing insulation, structure, windows, exterior rain screen and interior finishes complete the cladding.

Description from architects

How can we holistically transform the way we make architecture, compressing the construction timespan and making use of technology to create a truly sustainable, aesthetically moving shelter?

Loblolly House was inspired by the childhood urge to build tree houses. An effort to bring back the magic of a house in the trees — one that requires climbing up to gain a view — Loblolly House appeals to a primal instinct about how we inhabit space. It also represents a home that is uniquely integrated with its setting among the tall loblolly pines from which it takes its name.


Positioned between a dense grove of pines and a lush foreground of saltmeadow cordgrass leading to the bay, the prefab modular elevated home on stilts is formed about and within the elements of trees, tall grasses, the sea, the horizon, the sky, and the western sun. The skewed piles upon which the foundation rests mimic the form of the forest, fusing the natural elements of this barrier island to architectural form.

Loblolly House also reflects an environmental ethic; by lifting it off the ground, we ensure that it touches the site very lightly. Our desire in conceiving this stilt home was to reimagine what was possible in the realm of building — with the intention to improve the productivity of design and construction, enhance affordability and quality, and do so in an ethical and aesthetically moving manner.


Most houses are built from thousands of parts, which are transported separately to the construction site and pieced together by hand — a process of extraordinary duration, cost, and environmental impact. With the prefab home made from pre-built modules, by contrast, we wanted to use integrated assemblies of those parts, fabricated off site, to build a house in an entirely different way. Specification was no longer structured around the 50 divisions of the Construction Specifications Institute traditionally used to organize the multitude of parts. Instead, the conception and detailing were formed about four new elements of architecture: scaffold, cartridge, block, and equipment. The connections between elements were designed to be made using only simple hand tools.

Each element — and its junctures with other elements — was first digitally modeled to an exquisite level of detail. At the time, in 2004, parametric modeling software was in its nascent stages and required significant effort, but its use ensured that elements fabricated simultaneously would fit together perfectly. The assemblies were then fabricated off site, anticipating their attachment to the aluminum scaffold system that would eventually support and connect them. Unlike a traditional building process, in which construction must happen sequentially from the ground up, with the prefab home made from pre-built modules, the various elements could be prepared at the same time, shifting 70 percent of the effort to the factory. All of the modular prefab elevated home's systems were pre-integrated into the floor and ceiling panels, termed smart cartridges, to distribute radiant heating, hot and cold water, waste water, ventilation, and electricity throughout the prefab elevated house on stilts.


At the Taylors Island site, the building began with traditional, site-based preparation of the foundation. However, once the aluminum frame was in place, the assembly process could continue apace. Floor and ceiling cartridges and pre-built modules — including entire bathrooms and mechanical blocks — were lifted and fitted into place. Exterior wall panels containing structure, insulation, windows, interior finishes, and a wood rain screen of western red cedar completed the cladding. From the platform up, the prefab home made from pre-built modules was assembled in less than six weeks.

As you approach this modular stilt home from the 800-foot-long drive in the afternoon, when the sun shifts to the west, you can see a mysterious glow at its center: the orange glass of the footbridge connecting the main house to the guest quarters. Like its perch amidst the trees, this is one of the elements of magic to the structure of the prefab elevated house on stilts, accentuating the daily ritual of the passing of the sun. With this project, we wanted not only to envision anew the process of design and construction, embedding within it an environmental ethic, but also to create a house that evokes the extraordinary natural world that is its home.

This 440 sq ft 1 bedroom prefab home serves as a simple retreat space on the beautiful remote area outside an arts colony in Texas. It is the first of three prefab modules that are planned to install for the site. The module installed complete with an outdoor shed and a fully finished exterior and interior, leaving only sun-shielding canopies, decks and utility hookups to be assembled on-site.

Description by architects.

This weeHouse and its cool, calming interior serves as a simple 440 SF retreat space on the fairly remote site outside a small arts colony in West Texas. It is designed to be the first of three weeHouse modules that are planned for the site.

The module arrived complete with an outdoor shed (housing w/d + hot water heater) and a fully finished interior and exterior, leaving only utility hookups, decks and sun-shielding canopies to be installed on- site. A stepped foundation provides a proud platform for sweeping views of an amazing landscape.


The client wanted a modestly-scaled retreat that sat lightly on the landscape in a remote site, 20 minutes outside the small arts colony of Marfa, in West Texas. The initial house is a do-all outpost, the first of three modules that are planned for the site. The module arrived complete with an outdoor shed and a fully finished interior and exterior, leaving only utility hookups, decks and prefabricated sun-shielding canopies to be installed on-site. The architects sought to re-imagine the ideal of luxury based on size, instead looking to leverage the uniqueness of place through effcient multi-use space with simple, elegant detailing. They also concentrated design efforts on the process of producing high-quality work within a modest budget and a geographically challenging location.

The house is reduced to a floor and ceiling, the end walls creating a TUBE that locates a nexus on the landscape.

The simplicity of the living space and its amenities offer livability and a sense of luxury without detracting from the reason to be there in the first place: respite. Expansive decks promote outdoor living, the glass allows natural cross ventilation, and large awnings that block the intense SW Texas sunshine.


The remoteness of the site created unique challenges to delivering high quality architecture. The Client contracted with the Architect to purchase not only design services but also the actual house - as a product.- prefabricated in a modular factory. This gave the Architects complete control over the process: from concept to completion, and allowed the house to be "plugged in" with all electrical, infloor heating, and final plumbing items compelte upon delivery. 

The house is located in the high deserts of Texas and is a minimalist refuge. One room serves as bedroom, kitchen, dining room and living room. The adjacent room is a luxurious bathroom with views of mountains to the north and south. A prefabricated utility shed houses an outdoor kitchen and laundry,
leaving the rest of the essentials to the main module. 


  • Size: the project consists of a 15’ x 35’ house (525 sf of conditioned space) and a 4’ x 15’ shed, for a total of 585 sf.
  • Cost: modular work and design, $155k. Site costs withheld.
  • Structure: standard wood frame with simple “framing square” type bolt-on moment brackets to reduce cost, weight, installation labor.
  • Ceiling height: 8’.
  • Siding: fibercement panels and trim, painted with an oxidized latex paint with suspended iron filings.
  • Windows: standard Andersen 8’x8’ sliding doors.
  • Roof: Epdm rubber, vented.
  • Heating: The house is heated via wood-burning fireplace, on-demand electric boiler with hydronic in-floor heating located in the bath cabinet. A small 19-seer rated split wall AC unit provides all the cooling needed.

Curtain tracks are integrated into the ceiling/door trim.

About Easy Domes

Design: Easy Domes (Denmark)

Domes and polyhedron shaped buildings and designs are seen all around the world. Old and ancient examples are mostly churches, minarets, the arctic igloo. Today we have high-tech examples of geodesics from added super-domes in different sizes and materials, to simplified and nature orientated and sustainable buildings.

The structural behavior of Platonic polyhedra - from first experiments and full scale buildings made by Buckminster Fuller, architect and engineer, to other experiments showing the fact, that plate structures are not a type of lattice structure, but a independent type of structure with dual properties to the lattice structures. This was confirmed when the basic equation of stability for plate structures was found.

Plates and lattices are duals like axial and shear forces, like the closed and the open, and in the same way as yin and yang are incompatible, but yet form some interesting combinations.

Conditions of stability to convex singular coherent polyhedra, as combinations of these form the basis for nearly all buildings considered with characteristics of pi-free three dimensional geometry. Topology, stability and geometry are similar seen in quite different levels: The carbon molecule structure with 60 atoms on each vertice - similar to the geometry of the truncated icosahedron. Resent NASA´s Spitzer Space Telescope discovered small "buckeyballs" in space 6.500 light-years away stacked together in enormous structures hundred of millions of miles wide. In the biological world Radiolaria and Foramifera as high frequency plate polyhedra. The structural concept of honeycomb, and maybe a good example of pure plate structure, the sea Urchin.

Introducing the Easy Domes concept, the word easy can be regarded as a key word. The Easy Domes building kits are manufactured as high quality wooden sections ready for mounting at building site. The prefab dome construction is easy to assemble with only steel bolts and nuts. Small prefab domes can be erected by manpower while bigger prefab geodesic domes need a crane. The structure is suitable for all kind of terrain and implementable to any climate condition.

This page will highlight news and developments from around the world - in light of polyhedra to sinus related trans-formations - updated to new concepts, ideas as full scale examples.

The prefab geodesic dome home design offers an easy and quick assembling of the structure. On a timber or concrete basic it takes only one day to raise the building which is made of quality materials: 3x6" and 3x4” timber in pinewood and plywood. All sections are pre manufactured and ready to assemble with nuts and bolts and the sealing with rubber or asphaltpaper. This prefab geodesic dome homes are certified and with quality and precision installation, meet international building standards and rules. Delivery is easy in container and lifting crane is not needed to build structures until 50 SF. The prefab domes are proposed as passive or low-energy solutions with eco friendly energy efficient technology in heating and electricity.

Each prefab dome home is designed and manufactured for personal wishes on room arrangements, windows, in- and out- side building materials,  flooring, water- and energy supply a.m.

One prefab geodesic dome-building kit  includes the 21 wooden sections, the load construction, and two wall sections for main door. Fittings for mounting the sections are included a delivery.

Special designed windows in hard-wood or aluminum are to each delivery. Here aluminum-skylight are offered too. The needed aluminum flashing for  secure against rain, is the third manufactured product.

About Add a Room

Design and manufacture: Add a Room
Photography: Addaroom, Matti Marttinen

This small modular house is a concept from cooperation between Sweden and Denmark. The various modules can be connected in different ways to meet different needs and assemble a variety of designs, kind of lego structure blocks for adults. The house includes pergola and deck as well as possibility to link other facilities such as outdoor shower, prefab sauna and outdoor kitchen.

Interview with Owners and Designers

Would you like a holiday home but don't have the money for a big one? Well, why not start small, and then let the house grow by adding rooms?

It is in all its brilliant simplicity, the idea behind the Swedish company, Addaroom. Their modular house concept based on adding a room and that is exactly what the concept is all about.

Lots of design magazines have already spotted the Addaroom, and have written about the concept. So far, sales have not quite met the interest; But hopefully this will come now, states Susanne Aarup, who is the woman behind the Addaroom idea with her Swedish husband, Sven Hansson.

She has also found a company that will produce the cozy little house modules, namely Hansen & Larsen. And that it became the Dejbjerg company, is not entirely coincidental, says economist-educated Susanne Aarup.

She is from Højmark, Denmark, but has lived in Sweden for many years. When she and her husband were in searching of a producer and partner closer to the markets down in Europe than their hometown, Stockholm, she asked her siblings if there was a West Jutland company they could recommend. There was!

Production in Skjern

Hansen & Larsen were immediately on the idea. Karsten Larsen and his sister and brother-in-law, Dorte and Brian Meldgaard, who own the company together with Meta Larsen and Flemming Nissen, would like to spread the activities a bit more.

"We thought it was a good idea. Some times of the year there is not as much to look at as others, and we saw that in this way we could fill in some gaps", says Karsten Larsen.

"We started production last April. It's something completely new to us, so it took a little more time than we had imagined, but now we're running it in", says Dorthe Meldgaard.

"However, conditions in Dejbjerg are not entirely optimal, so we are considering moving production to Skjern. One of the advantages of building such small modular houses is that production can take place inside, and thus does not depend on the weather", says Karsten Larsen.

Karsten Larsen and Dorte and Brian Meldgaard believe so much that this type of modular house can face something of a breakthrough that today they are co-owners of Addaroom with Susanne and Svenne Hansson.

"The trend is towards these types of houses that are both simple and compact, and where outside and inside are merging. We are early in the trend and the crisis has left its mark; interest has been there but people have kept buying again. Hopefully that will change now", says Susanne Aarup.

Architectural Prefab Modular Design

"My husband and I got the idea when we saw that many Swedish holiday homes were in a bad condition. But replacing an entire house is a big step, so we thought, why not start small with something much more compact, and then add or subtract modules as needed", she continues.

She adds that the prefab house modules can also be used for other than leisure accommodation. She and her husband - who are carpenters - agreed that design and quality should not be given anywhere. The prefab houses are for year-round use in the North Europe climate and therefore they can easily be used for, for example, student or youth housing or in connection with holiday centers, or - why not? - on top of high-rise buildings!

Susanne Aarup also sees great opportunities in so-called business to busines, i.e. trading with other business companies.

The fact that Addaroom has aroused such high regard in design circles is not strange. Susanne Aarup and Sven Hansson have allied themselves with well-known architect, Lars Frank Nielsen, co-founder of the architectural firm 3xN; she came into contact with him through the furniture company OneCollection in Ringkøbing, their furniture she has in Sweden.

Lars Frank Nielsen also liked the idea. Together with Susanne Aarup and Sven Hansson, he designed an almost minimalist house that could easily be stand alone small prefab house, but which could also be assembled with several units.

Multiple Modules

The basic module is 15 or 20 square meters, i.e. 3x5 m or 3x6.6 m, and a porch of 3x2.4 m with pergola 3x1.5 m in extension of the small modular house.

These prefab modules can be connected directly to each other, or they can be connected with outdoor or indoor modules, so that you can create outdoor environments with atrium, outdoor kitchen and outside shower or, for example, get two separate sleeping areas with a shared bathroom and kitchen in the middle.

It has been a goal to blur boundaries between outside and inside as much as possible, so of course there is also a sauna module!

Prefab Sauna Module

"It's a year-round home we're building", states Susanne Aarup, and continues: "We have made every effort to make the houses so simple and to build them in such solid materials that only minimal maintenance is required. When you are in a holiday home, you do not want to spend the time on maintenance".

LocationYucca Valley, Mojave Desert, California

This off-the-grid modular prefab desert home in California is 1000 sq ft and situated in the arid region Yucca Valley. The main principles of the prefab modular house design are sustainability, adaptability, economy and durability. Emphasis was given to ensure minimal plot disruption while retaining privacy and maximizing views. Solar technologies provide space heating, hot water and electricity. The house was completed with an 8 week construction in 2009, at $270/SF.

Description by architects

A collaborative effort between o2 architects' Martin Brunner and Lance O'Donnell and Prefabricated Home developer Blue Sky Building Systems; this 1,000 square foot 1000 sq ft 2 bedroom modular home is located in the Mojave Desert region at 4,000’ above sea level. The program called for a sustainable, modestly scaled residence to serve as a prototype for a prefabricated line of homes. Special attention was paid to site placement and building orientation. Inspired by Le Corbusier's "Domino"; the building contains a pure structure of columns and planes. Adaptability is created by the non-load bearing walls and openings that can be moved within the structure to satisfy a variety of site conditions.

The 1000 sq ft 2 bedroom off-the-grid prefab modular home in California is positioned above the site on moment-resisting columns and beams of cold-formed, light gauge steel. The building envelope is composed by a grid of pre-manufactured wall panels and standardized building components. The bathroom module, containing all home MEP systems, is built off-site and delivered finished. Interior spaces are defined by the placement of storage cabinetry, eliminating interior framed walls. Solar technologies provide electricity, hot water and space heating.

The flat-packed building components minimize transportation volume and promote sustainability through material/structural efficiency and can be dissembled and relocated. The inherent nature of prefabricated design ensures low embodied energy and minimizes site waste. The 2 bedroom prefab desert home was completed in May of 2009 after a construction schedule of 8 weeks and a construction budget of $270/sf.
