Sliding walls
Multi-section sliding panels open the front almost completely, so you go from closed sunroom to open patio in seconds.


The Berlin Solarveranda is a German-made lean-to sunroom that attaches to your house wall and turns a patio into a bright, sheltered garden room. Its graceful curved aluminum frame rises from the ground to your wall, and the front is made of large sliding panels that glide open almost completely. Open it up on warm days for a shaded patio roof, or close it when the weather turns and enjoy a protected summer garden for plants, dining and relaxing.
Each Berlin is built to order by Hoklartherm (KGT) in Germany, the maker of the famous Riga greenhouses, and is sold in the US through Exaco. Choose from four depths (6 ft 7 in to 16 ft 5 in) and widths from 7 ft 1 in to 27 ft 8 in along your wall, in three frame colors.
Depth is how far the Berlin reaches out from your wall. Width is the length along your wall. Height is at the wall connection.

The Berlin Solarveranda is designed, engineered and manufactured in Germany by Hoklartherm, a leading manufacturer of hobby and commercial greenhouses, conservatories and garden structures.

Free curbside freight delivery
Choose your size, color and options. Your greenhouse ships from the manufacturer's warehouse, packed for freight.
We'll contact you to set up a delivery time frame that works for you.
Delivery is by LTL motor freight on an 18-wheeler. Let us know about tight roads or low wires so we can plan ahead.
Someone needs to be there to receive the delivery. The driver does most of the work but may need a hand.
Foundations and bases are bulky, so we recommend ordering them together with your greenhouse to avoid a separate freight charge.
