Larger, more expensive garden sheds are typically constructed of wood and include features typically found in house construction, such as windows, a shingled roof, and electrical outlets. Larger garden sheds provide more space for engaging in hobbies such as gardening, small engine repair, or tinkering. Some garden sheds have small porches or include furniture, which allows them to be used for relaxation purposes. In some cases, teleworkers and home workers in general who live in mild climates use small- to medium-sized wooden garden sheds as outdoor offices. There is a growing industry in providing “off the peg” garden offices to cater for this demand, particularly in the UK but also in the US. Garden shed owners can customize wooden garden sheds to match the features (e.g., siding, trim, etc.) of the main house. A number of decorative options can be added to garden sheds , such as dormers, shutters, flowerboxes, finials, and weathervanes. As well, practical options can be added such as benches, ramps, ventilation systems (e.g., in cases where a swimming pool heater is installed in a shed), and electric lighting. Garden sheds designed for gardening, called “potting sheds”, often feature windows or skylights for illumination, ventilation grilles, and a potter’s bench for mixing soil and re-potting plants.
