Modular staff housing: several units

Can a company house its teams in several modular homes on the same site? Models, scope and points to check.

Housing a team on an isolated site, or adding homes to an existing establishment, raises a recurring question for companies and local authorities: build conventionally, rent, or opt for modular housing that can be delivered as several units? AIIA offers modular homes from the Maison Collection, designed and built in the workshop for permanent or temporary residential use, which can be deployed in several units on the same site.

Understanding the subject

Because AIIA's models are built industrially in a workshop, the same model can be reproduced several times for a staff housing programme, rather than designing each unit to measure. Each home in the Maison Collection, from 40 to 160 m² depending on the model (Line, Level, Vista, Axis, Block, Form, Scope or Court), is delivered turnkey: structure, insulation, joinery and glazing, interior electrics, interior plumbing, fitted kitchen, fitted bathroom and water heater are included at no extra cost, whatever the number of units ordered.

The choice of model depends above all on the profile of the teams to be housed. A compact individual residence points rather towards the Tiny Collection or an entry-level Maison model such as Line (40 m²) or Level (48 m²); a family home or one shared by several people may justify a larger model such as Block (73 m², two bedrooms) or Court (160 m²). No feature beyond what each model's product page confirms should be assumed for professional use: some options, such as air conditioning, a terrace or furniture, remain customisation choices and not elements of habitability.

Going further

Deploying several units on a site remains governed by the same scope as an individual project. AIIA designs the modular homes, has them built and delivers them; the land, connections to the public networks (water, electricity) and administrative procedures (prior declaration or building permit depending on the combined floor area) always remain the responsibility of the company or local authority leading the project, never AIIA's. For a programme of several units, this scope must be planned at the scale of the whole site (access, networks sufficient to supply each home), not unit by unit.

The regulations applicable to staff housing, whether they fall under employment law or under planning rules for several buildings on the same plot, depend on the exact intended use of the homes and the status of the company. This point is not covered in detail in this article: it must be checked case by case, ideally with a legal professional or the local planning department. This article does not constitute legal advice.

Practical advice

Before structuring a multi-unit modular staff housing project, a few questions are worth asking: how many homes are really needed, and for what use, temporary or permanent? Does the site already have sufficient access and networks, or do they need to be created? Which administrative procedures apply to placing several buildings on the same plot? No documented multi-unit project has been published by AIIA to date: these criteria remain principles to check against your own project, not a case study already completed.
