How One DIYer Built a Premium 5.4m x 3m Garden Room with a Pent Haus Kit
When extra space became a top priority, one UK homeowner turned an unused area of their garden into a versatile 5.4m x 3m outdoor studio.
Designed as a true multi-use space, it functions as a productive home office by day and a quiet garden lounge for relaxing or entertaining by evening. Rather than paying £25,000+ for a fully installed bespoke build, they chose to take on the project themselves using a Pent Haus Self-Build Kit—delivering a durable, high-spec retreat at a fraction of the cost.
