  • Details & Specifications

    This stylish garden building boasts a modern design with a sleek flat roof. The entire Prima Standard structure stands under 2.5m high, which often eliminates the need for planning permission.

    The Prima Standard is spacious enough to accommodate a desk, chair, bookshelves, and additional office essentials. Crafted from robust 44mm timber, including a sturdy 19mm timber floor, all wood used is sourced sustainably and can be stained or painted to match your preferences. Factory finishes are also available for a more refined look.

    This comprehensive garden building kit includes double-glazed windows, all necessary fixings and fastenings, high-quality door hardware, and detailed assembly instructions. It's designed for easy DIY assembly over a day or two, requiring only basic carpentry skills. Alternatively, you can opt for professional installation by Garden Affairs.

    • Can I view your garden buildings?

      Yes. Our display centre and offices are at Trowbridge Garden Centre, Trowbridge, Wiltshire, BA14 0DT. We have a variety of garden rooms from our range available to view. With literally hundreds of models available and the option to customise, we do not have every model, but we do have a "bit of everything" so that you can get a feel for the quality and options on offer.
