Maintaining an estate of AIIA modular accommodation: documented guarantees, reduced maintenance, and what is not yet documented.
A single modular unit and an estate of several modular units do not raise exactly the same maintenance question. As soon as an outdoor hospitality operator deploys several units on the same site, maintenance becomes a matter of organisation at the scale of the estate, not just of a single dwelling.
Understanding the subject
In outdoor hospitality in general, maintaining an estate of accommodation covers interventions of different kinds: some are corrective, to repair a fault found during the season, others are more preventive, such as checking drainage and plumbing networks, servicing automatic watering systems, or frost-proofing installations before winter. Preparing the site before the high season, in particular bringing accommodation back into service after the winter, is among the tasks most often cited in the sector's professional guidelines.
For AIIA accommodation, part of this preventive maintenance is already covered by commitments documented from delivery: a 10-year structural guarantee on the steel structure and main welds against any manufacturing defect, a 5-year watertightness guarantee on the roof, walls and exterior joinery against water infiltration, and a 3-year installations guarantee on electrics and plumbing against any operating defect. Each module also undergoes a factory quality check before dispatch. Full details of these guarantees are available on the Our approach page and are the subject of a dedicated article on what the guarantees of a modular home cover.
Going further
Beyond the guarantees, the materials themselves are chosen to limit routine maintenance over time: galvanised steel treated against corrosion, class 3 or 4 treated timber cladding resistant to UV and weathering, powder-coated aluminium joinery. A maintenance guide is handed over on delivery of each unit. At the scale of an estate of several units, this means that the maintenance baseline of each unit remains comparable from one unit to the next, which simplifies planning compared with an estate made up of heterogeneous constructions.
Organising the operation of an estate nevertheless means adding a layer specific to managing several units: a guarantee calendar per unit, since each unit may be delivered on a different date, centralisation of the maintenance guides handed over on delivery, and tracking of seasonal deadlines (de-winterising, checking utility connections, inspecting outdoor equipment) generally recommended in the outdoor hospitality sector. AIIA, for its part, provides lifetime technical support and guidance from a dedicated contact for professional projects, from the study stage to delivery.
Practical advice
In practice, the professional maintenance guidelines for outdoor hospitality come back to a few simple habits: bring accommodation back into service before each high season rather than in reaction to a fault, frost-proof cold-sensitive installations before winter, and monitor the condition of shared outdoor equipment, such as play areas, over time. These general principles, specific to the sector, apply to any estate of accommodation, whatever its manufacturer.
AIIA does not currently publish a dedicated, costed maintenance programme specific to operating an estate of several units (for example, a contractual intervention frequency or the cost of a multi-unit maintenance contract): this data is not publicly available to date, and we prefer to say so clearly rather than assert it by extrapolation. Operators considering a project of several units can talk directly with our team dedicated to outdoor hospitality to assess the needs specific to their site.
