The basics of sunroom additions
A 200-square-foot sunroom addition, including footings and slab-on-grade foundation, post-and-beam construction that’s exposed on the interior, efficient windows, 10 operable skylights, ceiling fan, tile floor, and window shades, costs an average of $72,179 according to Remodeling magazine’s 2013 Cost vs. Value Report. You can expect to get about $33,529 of that investment (46.5%) back at resale, according to the study.
Since the whole point of a sunroom is to connect to the outside world, windows are a sunroom’s most important feature. A typical sunroom might have 20 windows, each costing from $250 to $1,200, depending on their style and quality. Choosing the right window type, material, and efficiency will maximize the beauty and function of your sunroom.
A cathedral ceiling (around $10,000) will give your sunroom a sense of spaciousness — and allow you to install skylights ($2,000 to $3,500 each, installed). These help to make the room feel like an indoor-outdoor space, especially at night, when you can watch the stars from the comfort of a rattan chair. As with windows, look for Energy Star-rated skylights to ensure that they’re efficient.
Ceramic tile makes the most durable sunroom floor because it won’t fade in the sunshine, get scratched by muddy boots, or stain where drinks spill. Plus, it’s nice and cool underfoot on hot summer day. A tiled floor costs $1,000 to $2,000 or more, depending on the tiles you choose.
If you want an area rug over the tile, today’s indoor-outdoor options are far better than the bright-green, plastic-turf style sunroom-rugs of yesteryear. You can get weatherproof carpet that’s soft and comfortable underfoot in nearly any color of the rainbow.
Window coverings control sun glare, improve the energy efficiency of the sunroom, and provide privacy at night. But traditional curtains can be too formal for a sunroom. Instead, consider pleated or cellular shades (also known as honeycomb) and wood or bamboo blinds.
You’ll pay $100 or more for wood and bamboo blinds per window opening; cloth, pleated, and cellular run $200 or more. There are even specially designed shades for skylights, which can drastically cut your air-conditioning costs.
A ceiling fan creates a gentle breeze that cools a hot sunroom — thanks to the wind-chill factor — and reduces the need for air conditioning, saving you money. Plus, it helps keep the sunroom warm in the winter, because as hot air rises, it pushes the heat back down on your family. Depending on style, ceiling fans run from $200 to $700.
