Portable Exterior Buildings

Portable Exterior Buildings

Speed Space offers a variety of portable exterior buildings to meet the demands of almost any application and any external condition. We offer standard features such as raised floors, heavy insulation, thermal windows, and steel frames for greater durability. We’ll also design your building according to state and municipal coding requirements, and consider environmental factors such as snow loads, wind pressure, and seismic activity. Our units are comfortable, attractive, and long-lasting; in fact, our standard exterior siding comes with a 40-year guarantee against chipping and color fade!

The uses of our structures are only limited by your imagination. From guard houses and blast-resistant buildings to custom coffee houses and produce stands, Speed Space has your solution.

What Are Portable Exterior Buildings?

Portable buildings are structures that, rather than being constructed on top of a solid or permanent foundation, are built on skid foundations. Skid foundations have lumber planks that sit on the ground and support the floor frame of the building. Equipment can then lift and move the building to new locations with relative ease.

While skid foundations were conventionally used just for sheds, they are becoming increasingly popular for a growing variety of exterior buildings, home additions, and office or commercial buildings. Portable buildings can be custom builds or modular buildings, and they offer easier construction possibilities and more affordable custom construction options. For example, homeowners can add space to their property by purchasing pre-built, modifiable portable offices and installing them in the yard.

Benefits of Portable Exterior Buildings

Portable buildings offer several advantages over conventional constructions. Some of the key benefits of portable exterior buildings are:

  • Flexibility: Portable buildings can be routed to remote locations, busy properties, or residential backyards. They also offer a wide range of features, interior design options, and layouts so they can be custom-built to exact specifications.
  • Cost-effectiveness: Portable exterior buildings are prefabricated at a factory, with many components often using the same mold. This allows manufacturers to charge customers less while saving them the hassle of sourcing their own construction materials and workers to assemble the building.
  • Eco-friendliness: Portable building materials are recyclable. Once the building is no longer needed, the materials can be sold to a steel company to make new steel products or made into another portable building.
  • Portability: One of the key features of these buildings is that they are portable. They can be transported to a different area of a property or between properties (such as if homeowners move or if a business expands to a new location).
  • Durability: Today’s portable exterior buildings are long-lasting and durable. They often feature the same materials and follow many of the same building codes as conventional structures and permanent buildings.

At every stage of construction, transportation, assembly, and use, portable buildings are designed to provide flexible options and cost-effective building solutions.

Portable Buildings From Speed Space

At Speed Space, we design and construct portable exterior buildings and stackable buildings. We provide in-house construction and fabrication services so we can guarantee the quality of every single- and two-story building from start to finish, and then we deliver the buildings and complete installation. Unlike traditional buildings, our modular portable buildings made of aluminum, steel, and/or wood are easy to maintain and repair.

Custom-built stackable buildings are ideal for control rooms, parking booths, scale houses, guard houses, and other settings requiring good supervisory views. They take advantage of overhead space and optimize the use of your property or floor area. You can even purchase a single story now and add another story later if needed.

Our modular offices have built-in thermal insulation, sound control materials, and weather shields that eliminate the need for expensive mezzanine superstructures or decking. They are constructed to comply with the standards set out in the Indiana Fire Prevention and Building Safety Commission IC 22-15-4-2.

Once manufactured, Speed Space installs the structure in your facility, and it can be disassembled and reassembled easily using cranes and forklifts. Request a quote to start building your custom portable building today.
