Classroom portables are relocatable buildings used to provide instructional or support space on a school campus. They are often brought in when enrollment rises, a permanent building is renovated, or a district needs space before a larger project is ready. The building may be new or previously used, leased or purchased, and placed temporarily or […]
Concrete prefab slabs, also called precast concrete floor or roof units, are cast and cured away from the building site, then transported and installed as part of a structure. Common forms include solid slabs, hollow-core units, double tees, and other prestressed or reinforced products. Some systems act as a complete structural floor; others receive a […]
Multifamily modular homes are residential buildings that contain more than one dwelling unit and use factory-produced modules or assemblies. They can include duplexes, triplexes, townhomes, stacked flats, courtyard housing, or larger apartment-style projects. The term describes a combination of building use and delivery method; it does not imply one standard layout, building height, code category, […]
The cost of a modular school building depends on what the district needs, what the manufacturer supplies, and how much work remains on the campus. A modular classroom price is only one part of the project. The full budget may include design, code review, site work, foundations, utilities, accessibility, delivery, cranes, installation, technology, furniture, inspection, […]
Small prefabricated homes can support older adults who want a more manageable home, an accessible layout, or a way to live near family while keeping a separate household. A compact factory-built house is not automatically senior-friendly. Its usefulness depends on the resident’s abilities and preferences, the site, the home’s code and approval path, access to […]
Prefabricated restroom buildings for parks are restroom facilities assembled in a factory or shop and delivered to a park for installation. They may arrive as a complete building or as panels and components that are assembled on the prepared site. The project still needs a suitable location, foundation or support system, accessible routes, utility connections, […]
A modular home is built in sections at a factory, transported to a prepared homesite, and assembled into a dwelling. The finished home is intended to remain at the selected property and connect to a site-specific foundation and utilities. Buying one for your lot involves more than choosing a floor plan: you also need to […]
The cost of a modular apartment building depends on the entire project, not only the factory price of its modules. The estimate may include design and engineering, factory production, transportation, foundations, crane operations, field connections, site utilities, permits, inspections, commissioning, and the land and financing costs that apply to any development. Because project scope, location, […]
Stick-built construction is a method in which a building’s framing is assembled piece by piece at the project site. The “sticks” may be wood members or, in broader usage, individual framing members such as steel studs. In U.S. residential construction, the term commonly refers to site-built wood framing for walls, floors, roofs, and partitions. The […]
A modular structure is a building or building section assembled from coordinated units manufactured away from the final site. The units may be three-dimensional rooms, two-dimensional panels, or repeated structural assemblies. They are joined at the site and integrated with foundations, utilities, circulation, and enclosure systems. The term describes how the structure is organized and […]
Design for Manufacture and Assembly (DfMA) is a design approach that considers how components will be made and joined while the design is being developed. In construction, it asks architects, engineers, contractors, and manufacturers to simplify and coordinate building elements so they can be fabricated, inspected, transported, installed, and maintained efficiently. DfMA can support prefabrication, […]
Modular building design is the process of planning a building as coordinated units or assemblies that can be manufactured away from the site and then transported, connected, and completed at the project location. It affects more than the size of a box. The module grid influences rooms, structure, façade, services, shipping, lifting, fire and acoustic […]
