Gardens attached to urban houses are generally small. Narrow gardens are best subdivided to give the illusion of greater space. Simplicity is the key to getting the most from a small space particularly courtyards.
You need to consider what uses you plan for your garden. Is it needed for play, entertaining, gardening or relaxing? Draw up an accurate plan to show existing features such as services, boundaries, trees, changes in level or views. Make a special note of aspect and which parts receive the most sun at different times of day or year, whether part of the garden is exposed to wind or is frosty in winter. You often need to live in the property for some time to assess these points. Photocopy the plan and then use the copies to try out different ideas and plans.
A well-designed garden will get the most from a small space and add value to the property. Designs can be by garden designers, professional landscapers or yourself. Many colleges offer part courses in garden design for the home gardener.
Beware planting large trees or tall hedges as they may overwhelm the garden and neighbours rather than provide privacy. Large trees and hedges can cast too much shade and make growing other plants difficult. Climbers on trellis can soften boundaries and provide year round interest. Larger shrubs or features such as arbours may provide a focal feature and privacy. Any feature plants should have more than one season of interest and successive planting such as spring bulbs under summer-flowering shrubs will give a succession of interest in a small space.
