Everyone weighing up an enclosed outdoor living space wants the same thing: real numbers, not a vague "it depends." It genuinely does depend on which type of enclosure you're after, but that just means there are four fairly distinct price bands rather than one number — from a basic screen enclosure through to a fully insulated glass room. Here's what actually sits in each band, what pushes a quote up or down within it, and the costs that catch people out because they're not part of the headline figure.
What Drives the Price Up or Down
Four things move a quote more than anything else: which enclosure type you choose, the size of the area, whether you're adding climate control, and how much work is needed to tie it into your existing roofline and home. A screen enclosure on an already-covered deck is a relatively contained job. A fully insulated glass room with double-glazing, a split system and new electrical circuits is a much bigger undertaking — closer to building a new room than adding an accessory to one. At a glance, here's roughly where each enclosure type sits:
- Screen & mesh enclosures: approximately $10,000–$18,000
- Hybrid systems (mixed glass and screen): approximately $18,000–$32,000
- Retractable glass wall systems: approximately $28,000–$45,000
- Fixed, fully insulated glass rooms: approximately $42,000 and up
Those are starting ranges for a straightforward job on an existing covered deck or patio — the sections below cover what typically pushes a given project toward the top or bottom of its band.
Screen and Mesh Enclosures: Price Range
Screen and mesh enclosures are the most affordable way in, typically landing between $10,000 and $18,000. You're paying for framing and fine mesh panels rather than glazing or climate control, which keeps material and labour costs down considerably. Where you land in that range mostly comes down to the size of the area and how much of the existing structure — posts, roofline, flooring — is already in place and usable versus needing rework. It's a three-season solution rather than a genuinely climate-controlled one, which is the main trade-off for the lower price.
Retractable Glass Systems: Price Range
Retractable glass wall systems generally run $28,000 to $45,000, sitting above screen enclosures because you're paying for a sliding or folding mechanism and proper glazing rather than fixed mesh panels. The payoff is flexibility — open the space up entirely on a good day, seal it off completely on a bad one. Price within this band is driven mainly by the width being enclosed (more panels means a longer track and more hardware) and the glazing spec, since better-performing glass costs more but pays off in comfort and running costs long-term.
Fixed Glass Rooms: Price Range
Fully insulated, fixed glass rooms sit at $42,000 and up, and it's not hard to see why once you break down what's included: double-glazed panels, insulated roof systems, proper sealing, and usually a heating and cooling solution like a split system or radiant heaters. This is the option that genuinely functions as year-round living space rather than a seasonal extra, and the price reflects that it's closer to a small home extension than an add-on. Larger footprints, higher-spec glazing, and more involved climate control all push a quote toward the upper end of this band.
Hybrid Systems: Price Range
Hybrid systems — glass on the weather-exposed side, screens on the sheltered side, sometimes a solid insulated panel on the western wall to block afternoon sun — typically land between $18,000 and $32,000. Because it's a mix-and-match approach built around your specific site, the exact figure depends heavily on the ratio of glass to screen: a hybrid that's mostly glass will sit toward the top of this range and start to overlap with retractable systems, while one that's mostly screen with a small glazed section will sit closer to the bottom.

Hidden Costs People Forget (Council Fees, Electrical, Insulation)
A few costs regularly catch people out because they're not part of the headline per-project figure. Council fees and engineering — where a Development Application or an engineering certificate is required — add a genuine line item, and it's worth confirming with your builder whether that's already folded into the quote or sitting on top of it. Electrical work for lighting, powerpoints, and any heating or cooling system is another common add-on, especially on a project moving from mesh to glass where climate control gets added partway through planning. Insulation upgrades — roof panels, sealing, sometimes wall insulation on a hybrid system — matter more in Canberra's climate than in milder states, and skipping them to save money upfront usually shows up later as high heating and cooling bills. Flooring transitions and matching finishes to the rest of the house can also add cost if the existing deck or patio surface isn't suitable as-is.

Getting an Accurate Quote for Your Block
These ranges are a genuinely useful starting point, but the number that matters is the one specific to your deck or patio — its size, orientation, how exposed it is, and what condition the existing structure is in. A free site visit, as part of our custom deck design and build process, is the fastest way to turn a range into an actual figure, with a proper breakdown of what's driving the cost for your particular space rather than a guess over the phone. If you're ready to see what an enclosed outdoor living space would cost for your home, our team can walk the site with you and put together a detailed, no-surprises quote.
