Raised chicken coop with slatted floor and wide roof overhang near the coast

Coastal Humidity Coop Plan

Raised, cross-ventilated housing for damp air and salt wind

This layout was drawn for the KwaZulu-Natal and Eastern Cape coast, where a coop rots long before it freezes. Damp bedding, salt-laden air and summer downpours do more damage to a run than any cold snap, so the plan starts from drainage and airflow rather than insulation.

The structure sits on a raised platform with a galvanised frame and a slatted floor, which keeps litter off the ground and lets moisture fall through instead of sitting under the birds. The ridge vent is screened so driving rain cannot blow straight in, and the roof overhang runs to 600 mm to push water clear of the walls.

Frame and floor

Galvanised frame on a raised platform, slatted floor above grade. Bedding stays dry through humid summers and can be scraped out without lifting boards.

Roof and ventilation

600 mm overhang on all sides, screened ridge vent, cross-flow openings on the leeward wall. Air moves through without rain or salt spray following it in.

Wall panels

Treated pine or marine ply, with a fittings schedule that flags where stainless replaces mild steel. Hinges, screws and latches are the first things to fail near the sea.

Run and drainage

Dimensions assume sandy or clay ground. A gravel strip runs the full perimeter so runoff has somewhere to go instead of pooling at the door.

Where it suits

Best for coastal smallholders running six to ten birds. Inland, the Highveld winter plan handles frost better than this one does.

What it is not

Not an insulated build and not a predator solution on its own. Pair it with buried mesh if jackal or mongoose work your perimeter.

Request the Coastal plan

Ask about panel specs, or compare it with the Highveld winter layout before you commit to timber.

Who drew the Coastal Humidity Coop Plan

The layout was put together by Marlene Fourie, who has kept dual-purpose birds on a smallholding outside Port Shepstone for eleven years. Most of what she knows about damp housing came the hard way: a first coop built like an inland design, with a solid timber floor and mild-steel hinges, that turned into a mould problem by the second summer and needed new door hardware twice in three years.

Since then she has rebuilt twice, worked through slatted floors, marine ply and galvanised frames, and now runs about forty birds across three raised units. Her notes on this plan come from that rebuild, plus feedback from keepers in Ballito, East London and the Tsitsikamma who tried earlier versions and reported where water still crept in.

She is not a builder by trade. The plan is written for someone with basic tools, a level and patience, and it flags the points where a welder or a carpenter is worth calling in rather than improvising.
