The type of furniture you need should be the first consideration. If you prefer modern or rustic wooden chairs and tables, make sure to use both functional and comfortable things.
If you’re going to use cushions and pillows, make sure they’re weather resistant and can withstand the heat, wind, and rain. Second, decide on a lighting scheme. If you don’t have access to an electrical socket, candle lanterns or battery-powered fairy lights are good options.
Finally, consider incorporating a large number of potted plants. Summer not only brings out the best in most plants, but it also brings out the best in some flowers and greenery, which help to create a welcoming and lively porch.
