Most modular camp projects are decided by things that never appear on the unit drawing: how a truck reaches the pitch, where the crane stands, and how a service trench is routed without crossing a guest path. These are site questions, and they are cheaper to answer before the unit is designed.
Access decides the module
The largest unit that can be delivered is set by the narrowest point on the route: a village street, a bridge, a hairpin bend, a gate. Width and length limits translate directly into the floor area available, and therefore into the room programme. Confirming the route with photographs and measurements at the start prevents a design that cannot arrive.
On site, the same applies to the final approach. A unit placed thirty metres from the road needs a surface that can carry a delivery vehicle and a crane, in weather that may not be dry.
Ground and foundation
A camp on sloping ground or in a flood-prone valley needs a foundation strategy that suits both the terrain and the possibility of relocation. Screw piles and isolated pads are common because they are quick and reversible; strip footings suit flatter, more permanent layouts. Whichever is chosen, the level tolerance between units should be agreed before the frames are fabricated.
Spacing, privacy and view
Guests judge a camp by what they can see and hear from the bed. Unit spacing, orientation and screening matter more than facade detail. Two identical units can feel entirely different depending on whether the glazing faces a ridge or the neighbouring deck.
This is also where modular planning helps: because units are repeatable, testing three or four site layouts is quick. It is worth doing before fixing the unit type.
Services and phasing
Water, power, drainage and data have to reach every unit, and in a phased camp they have to reach future units too. Routing services along shared spines, with accessible connection points, avoids reopening finished paths each time the site expands.
Phasing has a second benefit: a first cluster can prove the concept and the operating model before the capital for the rest is committed. It also allows the second phase to correct what the first one learned.
Weather and season
A site that closes for winter needs units that can be shut down safely: drained services, protected exteriors and interiors that tolerate low humidity and cold. A site that operates year-round needs the opposite emphasis — thermal performance, ventilation and condensation control. Both are design decisions, not operating habits.
What to settle first
Before choosing a unit family, settle the route, the foundation approach, the service spine and the phasing plan. Those four decisions constrain the unit far more than a facade preference, and they are much cheaper to change on paper.
