Prefab Outdoor Office

Heinrich Brothers, Inc. will help you find a prefabricated building, prefab guard shack and prefab outdoor office to meet your needs.
We sell and install standard and custom fully assembled buildings, as well as modular building kits. Whether you require an outdoor building for a prefabricated guard house, prefabricated equipment enclosures, prefab guard shacks or booths, a lunchroom, or a cleanroom, we can help.


Heinrich Brothers offers two types of prefabricated office buildings and prefab guard booths. The first type is together and forkliftable, and the second type is not together and is modular. Each type of prefabricated guard booths and prefab office building has its advantages. A forkliftable building is a good choice if you want a structure that you do not need to put together. On the other hand, a modular building is the better option if you do not mind putting the building together and want a prefab office for the warehouse.


Prefabricated Buildings Components:

The components in our prefab builds are of the highest quality. You have several options to choose from when it comes to the wiring posts, panels, electrical components, roof, ceiling, deck, and windows.


Wiring Posts:

Wiring posts in the prefab guard shacks are either 20ga or 16ga painted steel or 6063T-5 aluminum extrusions with a satin anodized finish. In addition to supporting the structure, all posts act as wiring chases and have friction fit (steel posts) or snap in (aluminum) cover plates to allow easy access for electrical and telecommunications wiring. The non-progressive post design allows you to replace or rearrange the panels without impacting adjacent panels or ceiling.



Panels are either 1-3/4″ or 3″ thick and available with vinyl covered 1/8″ hardboard or 1/2″ gypsum with polystyrene cores. Other surfaces available for prefabricated warehouse offices include painted gypsum, FRP, 24ga Steel, and cement board. Custom Colors are available in most surfaces, consult the factory.



Lights are 160Watt 2×4 lay-in T-8 fixtures with an acrylic lens. Single pole and 3-way switches as well as duplex outlets are provided in accordance with a standard layout. Circuit breaker panels consists of 125A panels with 70A main breakers. Individual breakers are 15A. Electrical wiring, conduit, and light bulbs are furnished by others.


Roof Deck and Ceiling:

Roof deck is painted 22ga corrugated B-deck. Ceiling is acoustical grid type, including white metal grid, hangar wire, and 5/8″ thick 2×4 lay-in fiber board tiles.

Outdoor buildings often arrive pre-assembled, and there are limits as to what you can ship on a flatbed truck or trailer. Outdoor buildings that are for prefabricated guard shacks, equipment enclosures, prefabricated modular offices, restrooms, or locker rooms can ship as multiple prefabricated pieces or sections and joined together once they arrive at the destination.


Doors and Windows:

We have standard pre-hung doors in the prefab guard booths 3070 (3″ wide x 7″ tall) x 1-3/4″ thick. Hardware includes hinges, weep, and a key-in-knob locket. Windows are 1/4″ thick tempered safety glass preinstalled in anodized aluminum frames. Standard glass dimensions are 37″ tall by full panel width.
