Pecasa is a Watford garden room company. We design and manufacture bespoke, fully insulated garden rooms at our factory at Unit 3, 8 Colonial Way, Watford WD24 4PT, and install them across Watford and the surrounding area. Prices start from £23,000 including VAT for a 3 m × 2.8 m garden room. Every Pecasa building is bespoke, and your final quotation reflects the design, specification and site requirements.
Our Watford site is a factory and showroom. You can see samples of our cladding, flooring, doors and finishes, and talk through your design with our team. Visits are by appointment only. The showroom displays materials; we do not have a completed garden room on display.
Opening hours: Monday to Friday 9:00–17:00, Saturday 10:00–14:00 . Call 020 8146 2200 to book.

Contact us to book your free design consultation. A member of our survey team visits, measures your garden in Watford, checks access and discusses how you will use the room. It usually takes 10–30 minutes. You will also receive a free 3D design and a written, VAT-inclusive quotation, normally within seven days of your survey.
