One of the main features buyers look for in a home is an attractive outdoor area – the bigger the better – preferably with an easy connection to the living room and kitchen.

If you're a vendor, it pays to address the issue of outdoor space before putting your home on the market. According to real-estate agent Angus Campbell-Jones of Campbell Jones Property in Bowral, NSW, a well-designed and integrated outdoor room can add as much as 10 per cent to the value of a house. "More importantly," he adds, "it can make the difference between a sale or no sale."

If you are a buyer looking at a home without an existing deck or patio, consider whether it would be feasible to create one yourself. The answer may determine whether or not you should make an offer.

For houses, the options are fairly straightforward. Depending on the lie of the land and aesthetic concerns, you could build a deck, lay a concrete slab or define an entertaining area with paving. The choice of finishes is endless. Timber can be oiled, painted or stained. Pavers come in concrete, clay or natural materials such as sandstone. There are some fabulous new concrete pavers on the market that mimic natural finishes.

To be truly functional, an outdoor area should be covered so that it can be used in all weather and throughout the year. Here again, there's plenty of choice – metal or polycarbonate roofing, sails and awnings in fixed or retractable styles.

To make the whole package work well, it pays to install a wide opening between the indoor and outdoor living zones. This is both a functional and a visual element, blending the two rooms into one large living space with a common aesthetic. What you can do depends on the structure of the house and how much you're prepared to spend. If there is an existing window, the job should be relatively easy since the opening will already be supported. The options are french, bifold, sliding or stacking doors, in timber or aluminium.

If you live in a unit, adding an outdoor room is trickier. If your property is on the ground floor, you could seek permission from the body corporate to pave or screen off an area outside your unit. A more ambitious approach is to persuade the body corporate to retro fit larger verandahs to all units. Or perhaps you could fit an awning over the space, create a wider door opening or cantilever a barbecue off the railing. Sometimes all that is possible is to creatively furnish an existing verandah. Whatever you achieve, improving the indoor-outdoor interaction in your home will add value to the property.
