In modern architecture, there are many methods of
prefabrication. Since it is still an
evolving field of study, many firms experiment with different approaches and
strategies. Some assembly techniques
work well for certain building types and in specific environments while others
may differ in their benefits. Most of
these experiments in off-site fabrication occur in the housing market due to
their little value. Houses are cheaper
to build, so if the new technique fails, it has little impact whereas it would
be unethical to experiment on a large public building. There have been many designers in the past
decade that have chosen to specialize in prefabrication and see its potential.
The
ultimate form of prefabrication would be to complete the building in its
entirety before arrival to the site.
Issues arise very quickly when trying to accomplish this task
though. Limitations in size appear to be
the biggest issue with this approach.
The building can only be as big as the means of transportation that it
takes to arrive on site. For most cases,
this means the size is determined by what fits on a truck. Usually the width of the unit must be sixteen
feet or under to fit within most transportation laws. With the size limitation being such a strict
constraint, these drop in place buildings are usually small retreat shelters or
tiny homes. Studio Aisslinger created
one of these drop in place shelters in 2003 labeled as the LoftCube. The firm began to sell these small cubic
shelters to be used in all sorts of locations.
Structurally they were steel frame boxes skinned with fiberglass to
create a futuristic look, while being easy to fabricate. These boxes could be designed to serve
multiple functions – retreat houses, viewing cabins, etc.
If
dropped in place prefab had limitations with size what then would be the
remedy? Modular construction provides a
pretty successful solution. By splitting
the building up into different modules that each fit within the transportation
constraints, larger buildings can be constructed. Many houses are currently being sold as
modular units which usually are comprised a couple four to five modules. These units are craned in place with
everything complete except for the exterior façade. This can drastically reduce the on-site
construction time on a project which can be very desirable for housing
developments. There are multiple firms
that specialize in modular construction such as Hive Modular, Square Root
Architecture, and RES: 4 Architecture.
RES: 4 Architecture breaks down the programmatic spaces of a house into
their basic shapes and then uses those building blocks to create custom houses
using a modular approach. This
self-titled, “Modern Modular” process works well for the firm which has dozens
of completed homes across the United States.
Their first project, the Dwell Home, was created using five modules to
create an L shaped house. The project
not only was prefabricated, but it provided a well-designed, site specific home
to the client.
