Build a warm, sturdy cat shelter your cat will actually use
A complete guide from blueprint to construction — dimensioned plans, a full materials & tools list, seven illustrated build steps, and thermal, load & wind verification. No more flimsy, badly-sized commercial houses.
Everything you need to build it right
Every measurement, material choice, and step is based on a real build for an adult domestic shorthair (4–6 kg).
Precise dimensions
Why every number — field-tested 70×50×55 cm internal sizing, 18 cm door openings, and 20° roof pitch — for a cat that can stand, turn, and sleep comfortably.
Full materials & tools list
A categorized bill of materials with specs and quantities, plus the exact hardware and tools you need. Nothing left to guess.
7 illustrated steps
Clear, sequential build steps with diagrams — from cutting wood and assembling the frame to insulation, roofing, and finishing.
Thermal performance verified
Real heat-loss calculations show the insulation cuts loss ~5× versus bare wood, keeping your cat warmer in winter.
Load & wind stable
Engineering checks confirm a >20× safety margin and no tipping risk — sturdy enough for years of daily use.
Maintenance & FAQ
A seasonal upkeep schedule and answers to common questions — including how to convince a reluctant cat to go inside.
A structure designed around real cat behaviour

Frequently asked questions
▸My cat refuses to go inside.
Place a familiar blanket or worn garment inside. Position the entrance toward a quiet, sheltered direction.
▸Do I need a door flap?
In winter, a clear plastic or heavy cloth flap helps retain heat while allowing free entry/exit.
▸Can I use reclaimed materials?
Yes — old pallet wood, foam packaging, or insulated delivery bags can be repurposed. Just ensure they are non-toxic, splinter-free, and have no sharp edges.
