How much will my project cost?

Often when people call us about a project, they have no idea how much something will cost – and why should they?

Building an outdoor project is not something you do every day. But we do it every day, so we have put together the following general price guidelines to help you plan for your project.


The word sunroom means different things to different people. Normally, we think of a sunroom as an insulated, heated, and cooled year-round space attached to your house. We build a sunroom with the same level of foundation, structure, trim, and finishes as the rest of your home. Our goal is to design and build it to look like it was always there rather than an afterthought.

Sunrooms usually have a lot of windows to let the sunshine in. Often, when people ask us to build a sunroom, they are addressing a specific need that their house lacks. Perhaps they want a place to sew, to read, or to gather with friends. Because sunrooms represent air-conditioned space, they add to the square footage of your house. That means a sunroom will directly add value to your home when you decide to sell the house.

Usually our sunrooms start at around $50,000, while the average price is around $70,000. We often convert existing porches into fully finished sunrooms, and the cost of these conversions is much lower, starting at $35,000 and averaging $45,000. The biggest cost factor in a sunroom is usually how it will be heated. We’ll determine whether it can be tied in to your existing HVAC system. If not, we can add a new system to heat and cool the new space. Room size and flooring choices can also have a significant impact on the cost.

Wood Decks

An attractively-designed wood deck made from premium decking boards with wood railings and a few stairs can run from $10,000 on up. Premium wood decking means the wood is mostly free of knots and defects. We have built extensive, large wood decks with lots of amenities for as much as $75,000.

The average cost of the wood decks that Archadeck of Central South Carolina builds is between $15,000 and $30,000. The biggest variables in the cost of a wood deck are size, height off the ground, choice of railing types, and deck skirting.

The range of choices here is almost unlimited, so it’s difficult to pin down pricing, but here are some guidelines:

  • Basic concrete patios are the most economical option, starting at $6,000.
  • Stamped and stained concrete patios start at $7,000.
  • Paver patios start at $8,000.
  • Natural stone patios such as flagstone start at $12,000.
  • Firepits range from $1,200 for manufactured block fire pits to $4,000 for custom stone fire pits.
  • Outdoor fireplaces can cost from $8,000 to $30,000 depending on size and stone choices.
  • Outdoor kitchens start at $10,000 up to $30,000 depending on size and choices of appliances.

Factors significantly affecting the cost of hardscapes include project size, soil conditions, drainage, slope, roots and rocks, and accessibility of the area. Your Archadeck design consultant can help evaluate these factors on your specific project.

These are some rough guidelines to get you started. Your Archadeck design consultant can help you understand your options and how they affect your budget. We encourage you to be prepared to openly discuss your budgetary ideas with us during your design consultation. Understanding your budget helps us propose something that will work for you. Once we agree on a specific scope of work and sign a contract, your price won’t change unless you decide to make changes along the way.
