Adding a conservatory to your house is a popular way to increase your living area and dazzle guests. To attract more homebuyers, you might consider expanding your property by adding a new room. Rather than spending a lot of money and time on an extension, you might increase your home's value with little effort. The addition of a well-constructed conservatory might add as much as 5% to the value of your property. However, like with any renovation, a number of variables might affect how much a conservatory actually increases the value of a home. Size and materials used are two of the most crucial factors.
