BillyOh Bella 8x8 vs Petra 10x8 for a Garden Gaming Room (UK)

Quick answer: Pick the BillyOh Petra 10x8 if you want desk depth + walking space for a gaming room. Take the Bella 8x8 if the plot is tight and you will keep the kit compact. Neither is a turnkey insulated office — both are garden-room shells.

UK buying reality

Honest UK caveats: (1) power is almost never included — budget a qualified electrician for an outdoor RCD-protected circuit; (2) damp/condensation kills electronics and rusts iron — plan a vapour barrier, dehumidifier, and ventilation; (3) size labels (8x6, 10x8) are external — measure internal floor before desk or rack layouts; (4) security matters for kits — upgrade locks/hasp; (5) planning — many small outbuildings sit under permitted development, but height, eaves, listed settings, and “garden office” use can push you into needing permission. Check your local authority; we are not planners.
