Garden Office in Forest Hill - A Happy Customer's Story

We recently built this spectacular 5m x 3.5m Maxi garden office for a Forest Hill couple who both work in creative industries. Their sloping garden presented an interesting challenge, but our clever design made the most of the gradient with a raised deck and stunning views across South London. The space features a generous workstation for two, a cosy reading nook, and floor-to-ceiling windows that flood the room with natural light. They’re absolutely thrilled with how warm and comfortable it stays year-round thanks to our premium insulation. The garden office has completely transformed their work life, giving them a professional space that’s separate from their Victorian home while eliminating their commute and saving substantial travel costs.

Family Room in Forest Hill - Customer Success

This impressive 7m x 4.5m Multi+ garden room has completely revolutionised how our Forest Hill clients enjoy their property. With three growing teenagers in their Edwardian home, they desperately needed extra space for family activities. The versatile garden building now serves as a multi-functional entertainment zone with distinct areas for gaming, movie watching, and a compact home gym. The contemporary bi-fold doors create a seamless connection with their landscaped garden, perfect for summer gatherings yet cosy enough for winter movie nights. Our clients tell us this purpose-built space has brought the family together in ways they hadn’t expected, providing the perfect teenage hangout that’s close enough for parental peace of mind but separate enough to give everyone their independence.
