Livingten Greenhouse By KGT/Hoklartherm

Description

The Hoklartherm Livingten is the most thermally advanced glass structure available in the United States — a premium dual-pane greenhouse engineered to deliver genuine four-season indoor-outdoor living regardless of climate. Its defining technology is a 22mm double-pane ISO safety glass system with a 14mm air pocket between the panes, achieving an R-value of 2.5 that virtually eliminates condensation and maintains interior comfort in conditions that would render a standard glass structure uninhabitable. Paired with a thermally separated aluminum frame — a proprietary composite cold-wall barrier that breaks the transfer of heat and cold through the frame itself — the Livingten operates at a level of insulation engineering that no single-glazed structure can approach.

Inside, the Livingten offers a soaring 10’8” peak height and 7’ sidewalls, creating an interior volume that accommodates everything from a fully furnished outdoor entertaining suite to a glass-walled executive office or a private wellness retreat. Every unit includes a full-length LED light bar and integrated electrical outlets, transforming the interior after dark into a glowing architectural feature. Three sets of double-sided roll-up shade curtains with a reflective aluminum weave are included as standard — not an optional extra — giving you immediate control over light and privacy. Two sets of lockable double sliding doors with 61-inch openings provide wide, accessible entry from both the gable end and the sidewall.

Available in three sizes from approximately 164 to 228 square feet, the Livingten is engineered in Germany by KGT/Hoklartherm to a standard of construction that is without peer in the US market. It represents the definitive answer for the buyer who refuses to let climate dictate how they use their outdoor space.

Why You’ll Love It

The Most Insulated Glass Structure in the US Market.

A 22mm double-pane glass system with an R-value of 2.5 is not incremental engineering — it’s a categorical difference. The Livingten maintains a genuinely comfortable interior in conditions that would make a standard glass structure unusable. For a property where outdoor living is a year-round priority, this is the structure that delivers on that commitment without compromise.

A Frame That Breaks the Laws of Thermal Conduction.

Most aluminum-framed structures transfer cold and heat directly through the frame, undermining even the best glazing system. The Livingten’s proprietary cold-wall composite barrier breaks that transfer entirely — the interior stays warm in winter, cool in summer, and condensation-free throughout.

Built for After Dark, Not Just Daylight.

The full-length LED light bar and integrated electrical outlets that come standard with every Livingten are not afterthoughts — they transform the structure into an illuminated architectural feature after sunset, suitable for evening entertaining, working late, or simply enjoying the garden in a different light.

Unlimited Potential, Fully Furnished from Day One.

Three sets of double-sided shade curtains with reflective aluminum weave are included as standard — not an upgrade. Two sets of 61-inch wide double sliding doors provide wide, unobstructed access from two faces of the structure. The Livingten is genuinely ready to use the day it’s installed.

An Architectural Signature for the Estate.

The Livingten’s two-tone design — anthracite grey exterior, light-reflecting silver interior — is a deliberate design choice that gives it a presence unlike any standard greenhouse or garden room. From the outside, it reads as a contemporary architectural statement. From the inside, the silver interior maximizes light and creates an interior that is as beautiful as it is functional.

Engineered for the Extreme, Available for the Exceptional.

A 120 MPH wind rating, 30 PSF snow load capacity, and German precision construction mean the Livingten is overbuilt by any standard residential measure — which is precisely why it inspires confidence for decades of ownership. This is the structure for the buyer who demands the very best.
