You can make a reasonably correct estimation of the price for the construction of your sunroom by making a research with respect to the material costs, labor costs and furniture items that you will need for sunroom construction. If you really intend to add a sunroom to your home you must not wait till the last minute as prices keep escalating with time and by delaying you may find yourself in an undesirable financial crunch at the time of construction. You need to first make a budget to include not only the best construction materials and labor costs but also the roofing materials, furniture items and heating and cooling equipment as well.
The price of your sunroom will vary according to its size and the materials required for construction as also on the area and the place of your residence. If you live in a place that has a relatively warm climate you may have to spend more on cooling equipment, whereas if you live in a cold climate expenses on installing and running a heating system may entail extra costs. You will do well to start planning small and as you proceed increase the area/space you think you may need because the bigger the sunroom, the higher will be the cost.
Although your sunroom does repay the major part of the cost you incur, still you would not like to add a $45,000 sunroom to a home costing $100,000 when other homes in the locality cost in the range of $85,000 to $90,000.
Depending upon the size of your sunroom, its design and the materials used the cost of building the sunroom can start from $10,000 and go up to $70,000. It would totally depend on the style of the sunroom, the desired features you require, the total area involved in the construction, the type of foundation needed for constructing the sunroom and the total labor cost required.

“According to NARI, the National Association of the Remodeling Industry(http://www.nari.org), a sunroom repays you back more than 70% of the cost that you invest on its construction”
The cost of building materials for an average sunroom comes to about $10,000. If you also need to build a deck add another $1500 to the material cost. Materials for the stairs will be another $250 and floor upgrading will cost approx $1200 additionally. Adding up everything the material cost will come to roughly $13,000.
As for the labor cost for the construction of the average sunroom it will be approx $10,000. Labor cost for deck construction will be around $1600 plus say another $300 as stair construction cost. Thus the total labor cost will be around $12,000. This needs to be added to the material cost estimated earlier. If your budget is constrained, you should opt for vinyl framework for your sunroom.
Aluminum framework for sunrooms is more costly than the vinyl framework. Wood framing is the costliest with the highest maintenance costs as well. When you use wood framing it will be best to use matching furniture, for example rattan or wicker furniture items, for giving your sunroom a natural and earthy look.
The cost of building a sunroom may seem to be huge but it is much cheaper than a traditional brick and mortar extension to add a den or a guest bedroom. You can save a big chunk it you opt for a do-it-yourself sunroom kit that will knock off the labor charges giving you much more value for your investment.
