A German-engineered sunroom that opens into a covered patio in seconds. The Berlin SolarVeranda by Hoklartherm attaches to your house, and its curved front panels slide open for an open-air pergola on nice days, then close into a sheltered, windproof sunroom when the weather turns.
Not sure which size or type fits? We'll pick it with you.
The Berlin comes in 4 depths (Berlin II to V, from 6'7" to 16'5" out from your wall), 7 lengths along the wall (Types 2 to 8, from 7'1" to 27'8") and 3 colors, so every project is a little different. Text us a photo of the wall you want it on, with its rough width and the height of your roofline or eave, at 732-806-7959. We'll recommend the right size and type for your space and send you a complete quote before you order.
We carry many sunroom, patio room and lean-to solutions, so if the Berlin isn't the perfect fit for your home or budget, we'll show you the options that are. See all garden & patio rooms →

Patio Roof, Pergola or Sunroom — You Choose, Day by Day
Traditional sunrooms overheat on sunny days. The Berlin solves that: its curved front elements glide open on Hoklartherm's Force-Assisted Sliding Technology (FAST), so on a warm day you're sitting under an open patio roof, and when it turns cold, windy or wet you slide them closed and stay protected on your terrace. Partly open them to fine-tune the temperature and airflow. A safety mechanism keeps the panels from dropping unexpectedly.
-
Converts in seconds: smooth, force-assisted sliding front panels and multi-sliding gable doors take it from enclosed winter garden to open-air patio lounge.
-
Fits where others don't: the mono-pitch lean-to design mounts against an existing wall and works well on homes with lower eave heights. It can even be installed on a balcony roof.
-
Comfortable all year: a lockable multi-panel sliding door with insulated glass, adjustable openings and optional roof vents with automatic or manual openers (Berlin III to V) keep the temperature right in every season.
-
Built to last: heavy-duty, warp-resistant aluminum and impact-resistant glazing, engineered in Germany to handle heavy snow and strong winds.
-
Glazing: the manufacturer recommends plexiglass for its strength and impact resistance; tempered glass is also available.
-
Room to spread out: from 6'7" to 16'5" deep and up to 27'8" long, in white, anthracite grey or silver/white aluminum, with other colors on request. Optional shading is available for the roof, the sliding panels or the full arch.

FAQ
How do I know which size and type to order?
The size (Berlin II to V) is how far it projects from your wall, and the type (2 to 8) is how long it runs along your wall. Text us a photo of the wall with its rough width and the height of your roofline or eave at 732-806-7959, and we'll recommend the right combination and send you a full quote before you order.
What if the Berlin isn't right for my home?
We have many other sunroom, patio room, lean-to and custom solutions. Tell us about your space and budget and we'll show you the best options.
Is it a greenhouse or a sunroom?
Both, depending on the day. Open, it's a covered patio or pergola; closed, it's a sheltered sunroom or summer garden you can use for plants, seating or dining.
Will it overheat in summer?
Much less than a traditional sunroom. Slide the front panels open and open the gable doors to let heat out, or open them partway to control the temperature. Optional roof vents add even more airflow on Berlin III to V.
Does my house need a tall wall?
No. The mono-pitch lean-to design is made for homes with lower eave heights, and it can also go on a balcony roof. Send us a photo and we'll confirm the fit.
Glass or plexiglass?
Hoklartherm recommends plexiglass for its strength and impact resistance. Tempered glass is available if you prefer it.
Is shipping included?
Yes, shipping is free.
Do I need a permit?
Often, since it attaches to your home. Requirements vary by town, so check with your local building department. We can help with the documents you need.
