Modern luxury in perfection

KOYA garden house is a space module with exceptional design, developed for aesthetic demands, while providing the user with the highest quality and comfort. 

In the design language of the product, the KOYA architects and engineers have placed particular emphasis on a cubist form that appears both angular and soft thanks to slightly rounded edges. Thanks to a metal and glass façade flush with the outside, the design garden house has a uniform appearance - as if it were made of one piece.


An integrated flat roof with internal drainage ensures that this modern garden house retains its external appearance. Slightly inwardly offset adjustable feet make the eye believe that the building is floating lightly.

The design garden house is available in several sizes and can be freely placed in your garden, terraces or other areas.

A KOYA garden house can be ideally used as a guest house, pool house or fitness room but also, for example, as a garden lounge. The system can also be designed and used as a modern vacation home and Tiny House.


The garden houses are made especially for you, with a special eye for detail, in Germany.


Delivery is made in whole and assembly is uncomplicated and performed quickly.


The luxury garden house is insulated and winterized. The exterior and interior can be freely designed according to your wishes.

We offer a wide range of options and valuable accessories, so each garden house Cube is unique.

Design the facade of your luxury garden house

The outer appearance of the KOYA design garden house is strongly defined by the high-quality facade elements.


Would you like your garden cube to be more open and transparent? Or do you want elements that are hidden from view at certain points? With a fine selection of openable and fixed glazed windows, doors and opaque side walls, we can customize each room module to meet the customer's individual needs.

The design facades were conceived by KOYA architects so that they are exactly in one plane with the outer skin of the garden house. Viewed from outside, there is no protrusion due to window or door frames. The same applies to the wall elements, which are also installed absolutely flush with the outer skin.


All in all, the facades, together with the metallic outer skin of the modern-looking garden house, form a uniform and harmonious overall picture.

In addition, all wall and window elements are insulated. This ensures year-round use in both winter and summer months. High-quality triple glazing with high insulation is used for windows and doors.

Wall and ceiling panels in KOYA luxury garden houses are always made with a solid 70mm insulation.

Configure the roof structure for your garden house Cube

Incidence of light through the roof or ceiling of the design garden house can greatly enhance the interior and the user's experience of the room. In addition, a skylight also provides additional daylight from above during the autumn and winter months. In the summer, a skylight gives you the option of venting heated, low-oxygen air and promotes fresh air and cross-ventilation within the garden room.


The flat roof of the garden house can be designed in three variants. For the KOYA system, you can get skylights with clean, harmonious lines, which are square or round. 

A very special highlight is the possible design of the garden house with an erectable sleeping roof. With this innovative KOYA product development, another room is created on the roof of the Cube within a few seconds, which can be used for resting, "power naps" or even for overnight stays.

Valuable accessories for your modern garden house


A modern garden house requires not only a special design, but also high-quality and practical technical equipment. For this reason, we can equip your garden cube with important accessories with the help of which your KOYA becomes a full-fledged residential building that is in no way inferior to a solid house.

The product can be optionally equipped with a heater, air conditioner, built-in sockets and so on.

During the development, the designers and architects have also paid special attention to a sophisticated lighting of the room. It has been proven that a balanced lighting concept contributes significantly to the well-being and mood in a room. If desired, KOYA can be equipped either with free power outlets or with permanently installed indirect lighting.

  • How much does a KOYA garden shed office cost?
    The prices for a KOYA home office vary depending on the desired size, facade design and the wide range of accessories. In our detailed price list with pictures and explanations you will get exact information about our exclusive products. Contact our customer service and inquire directly here!

Our placement department will be happy to assist you with the correct placement of your garden cube and clarify with you all requirements regarding the ground, fastening, etc. Also a visualization on the basis of a photo or a 3D representation can be very helpful for a better idea of the project.

  • Can I customize KOYA Office?
    Yes, you can design and configure your own personal Office Garden House within our range. If you do not find what you are looking for in our program, we can discuss your individual wishes together with our special department: These could be: -Special areas of use or requirements -Commercial use -Special sizes outside the KOYA program -Addition of several modules -Individual planning and visualization -Special facade and opening elements -Special colors or materials Together we will find the right solution for your needs.
  • How is the KOYA Garden Office built?
    KOYA Office Cubes are "Plug & Play" and are completely prefabricated in production. The finished modules are delivered as a whole via freight forwarding. For the assembly, only a truck-mounted crane is needed to place the garden house home offices in the desired location. The assembly and placement of the modules is supervised by a KOYA assembly team upon request.
  • How to make the foundation for a KOYA Garden House Office?
    KOYA should ideally be firmly connected to the ground. The best way to fix the module is to use small concrete bases at the corners of the KOYA. For this purpose, the room module has provided small adjustable feet with holes. Alternatively, prefabricated concrete slabs or a concrete floor can be used as a base. You will receive from us detailed instructions for the execution of the foundations. The dimensions of the foundations strongly depend on the size of the ordered room module and therefore vary for the different models. In order to save costs, the foundations are ideally implemented by a GALA construction company (gardening and landscaping) in your vicinity. After delivery, the adjustable feet are then connected to the foundation by means of concrete anchors.
  • How is the power connection made?
    The Office Cube requires a 230V connection. The connection is laid by an electrician with an underground cable to the desired installation site. The cable for the power connection is located on delivery, open, on the underside of the garden house. For legal reasons, the connection of the connection or the connection to the power source may only be made by a certified electrician. Upon delivery of your garden home office, the electrician will establish the power supply with a waterproof plug. Then your Office Cube is fully ready for use.
  • How is the Office KOYA transported?
    The transport of your individual garden office is carried out by a forwarding company we trust. KOYA is prefabricated in the factory and delivered fully assembled. Complete transport of the finished product means less stress for you on site with a tedious assembly, which is usually necessary with other manufacturers and takes a lot of time in addition to the cost.
  • What are the delivery times for a KOYA Office Cube
    KOYA is a product that is manufactured individually for you according to your wishes. The current delivery times are seasonal and will be communicated to you in writing together with our offer. You can usually get a first estimate already in a conversation with our sales team.
  • Is a garden shed office tax deductible?
    In principle, a garden office is easier to deduct for tax purposes than a home office in a private household, as the question of use never arises with an external home office. In the case of a garden office, all costs from the purchase to the maintenance and the operating costs can normally be claimed against tax. Annoying questions of the tax office regarding the exclusive use or the actual working time spent in the office are completely eliminated. What to consider when using a Gratenoffice for tax deductions: -The garden shed office should be detached if possible and not connected to the house. -Use exclusively as a home office - No garden shed, no garden tools, etc. -The year-round usability by means of thermal insulation should be given. - The equipment of the garden office should correspond to a Arbeitsplat, at which can be worked all year round.
