ONKO Large Owl House 23x14x10 in – Outdoor Nesting Box for Great Horned Owls, Weatherproof & Easy Assembly

A spacious home for larger owls

The ONKO Large Owl House is designed to welcome bigger species such as Great Horned Owls and Barn Owls. Exterior dimensions measure 23 by 14 by 10 inches, while the interior offers about 13.78 inches in length, 10.24 inches in width, and 22.83 inches in height. This thoughtful sizing mirrors natural tree cavities and provides generous space for adult owls to move, stretch wings, and nurture their young without feeling cramped. The elevated build keeps the interior away from ground moisture and typical hazards, creating a discreet sanctuary in outdoor spaces.

Weatherproof and durable shelter

Constructed from waterproof materials, this owl house stands up to seasonal rain and wind while keeping occupants dry and comfortable. Ventilation holes and a smart drainage system prevent moisture buildup and help maintain a stable interior climate. The sturdy panels resist warping and decay, offering a reliable nesting environment year after year.

Easy to install and maintain

Despite its generous size, setup is approachable for a single person. The panels align for a precise fit, and all hardware plus clear instructions are included with no special tools required. A secure latch enables quick access for debris removal and routine checks, helping maintain a tidy habitat.

Ventilation, moisture control, and hygiene

Angled side panels create balanced airflow while built in gaps promote ventilation. Moisture management helps keep the interior dry and comfortable for nesting and roosting. Regular inspections and light cleaning support a welcoming and long lasting nesting site.
