Contemporary architects, inspired by the presence of affordable and versatile materials and technology, are producing designs for a wide variety of covered, private and recreational spaces. And hot on their heels are the manufacturers with desirable, stylish constructions, whether off-the-shelf or custom designed. Many are easy-build and often eco-friendly. This book aims to inspire anyone who would like to expand their living space: whether to create a conservatory extension or covered roof terrace, convert an existing outhouse or design a freestanding space at the bottom of the garden. This book presents designs, sizes and uses - from the smallest lean-to reading room to an elegant pavilion for special entertaining. It also features detailed case studies and practical guidance on how to work with architects and builders and source materials.
