"This is perfect for what I needed for storage in my backyard. Purchase went smoothly on the website. Thank you"
Tracy. K
"We desperately needed a backyard house but they’re astronomical prices. I came across NO Bull Shed online and was surprised with the prices and the great reviews. We went ahead and paid for the install too which was so easy and efficient. The guys did a great job! It’s a very nice quality budget shed!"

"Purchased a 9". Installer arrived at scheduled time. Completed the entire install in less than 6hrs. I was skeptical about the quality but it is a solid diy cube. Plenty of room. 100% satisfied."

The largest MO House in the range, offering 11.4 m² of insulated interior space for a more complete backyard office, studio, guest room, or private retreat.
The MO House 2.3 × 6.0 m gives you significantly more room to create distinct living and functional zones while maintaining the clean, narrow profile of the MO House collection. Its 11.4 m² interior is well suited to layouts that combine a workspace, sleeping area, lounge, hobby space, or other everyday uses in one compact backyard building.
The structure is built from pinewood and insulated with 100 mm stone wool through the walls, floor, and roof. Pinewood cladding finishes both the interior and exterior, while the standard set also includes linoleum flooring, electrical installation, painted wooden windows and doors, and an internal wall with a sliding door.
Large glazed openings across the front bring natural light into the main room and give the building a contemporary architectural appearance. Delivered assembled, this model is designed for buyers looking for a substantial insulated backyard room rather than a basic garden shed or unfinished shell.
Why Choose the MO House 2.3 × 6.0 m?
11.4 m² interior: The largest MO House size gives you more flexibility for work, guests, hobbies, relaxation, or a multi-purpose backyard room.
Fully insulated construction: 100 mm stone wool insulation is used in the walls, floor, and roof.
Separate interior zone: An internal wall with sliding door helps divide the space into distinct functional areas.
Bright contemporary design: Large painted wooden windows and double doors create an open connection to the outdoors.
Finished surfaces: Interior and exterior pinewood cladding plus linoleum flooring are included in the standard structure.
Electrical installation included: The building comes prepared with electrical installation as part of the standard set.
Delivered assembled: The main structure arrives assembled for a more straightforward installation process.

Warranty
Your structure is backed by warranty coverage based on its delivery and assembly format.

Customer Reviews
Overall rating: 5.0 / 5 from 3 reviews.
We use the Aspen as a guest room for my parents. They particularly appreciate having their own bathroom and not needing to come into the house at night. From the outside it looks very modern, but inside the lighter wood makes it feel warm and welcoming.
This is now my full-time backyard office. I added a monitor setup and a comfortable chair, and there is still space left for someone to stay overnight. Walking a few metres through the garden at the end of the day is a surprisingly good substitute for a commute.
We needed a real extra room, not just somewhere to store things, and the 6 metre model finally gave us enough separation between sleeping, working and washing areas. My partner can be at the desk while I read on the bed without us sitting on top of each other.
We want you to be able to enjoy your space as you like. Customize it by your preferences with our team.

Our collection includes different types of premium timber structures, from flat-packed DIY backyard studios to fully assembled and insulated modular houses. Each product page shows the exact construction, dimensions, delivery format, and included features for that model.
2. What is included with my purchase?
What's included depends on the product and configuration. Each product page includes a Standard Set showing the main components and features included with that specific model.
MO House models can include significantly more finished construction and features than DIY Cube models, so always refer to the individual product specifications.
3. Are the buildings delivered assembled?
Delivery format varies by product. DIY cubes are easy to assemble yourself and mo-houses you shall receive pre-built.
4. Are the buildings insulated?
It depends on the model.
MO House models feature insulated construction, including insulation in the walls, floor, and roof. DIY Cube models use a different construction system and should not be assumed to include the same insulation package.
Check the individual product's Insulation and Construction specifications for exact details.
5. What are the buildings made from?
The structures primarily use natural timber construction, with specifications varying by model. Depending on the product, this can include pinewood framing, timber cladding, insulated wall systems, timber flooring, and model-specific roof construction.
Exact materials and construction specifications are listed on each product page.
6. What can I use the building for?
Depending on the model, these structures can create additional space for a home office, garden room, creative studio, hobby room, workspace, gym, guest space, retreat, or other residential uses.
The intended use should always be considered together with the specific building's insulation, layout, utilities, local regulations, and installation requirements.
7. Do I need a foundation?
Yes. A properly prepared and level foundation is important for installation and long-term performance.
Foundation requirements vary between models. Where available, the appropriate Foundation Plan can be downloaded from the Plans & Resources section of the product page.
8. Do I need a building permit?
Permit, zoning, and building-code requirements depend on your location, building size, foundation, and intended use.
Customers should confirm applicable local requirements before ordering and installation.
9. Can I customize my building?
YES! And Available options vary by model. Depending on the building, options may be available for elements such as the facade, exterior finish, doors, windows, interior finishes, or other components.
Check the individual product's Options section or contact our team to discuss the configuration you're considering.
10. How is my building delivered?
Delivery depends on the selected model, configuration, and destination.
Some structures are shipped flat-packed for on-site assembly, while others, including MO House models, are transported as assembled modular structures.
Because these are oversized products, delivery requirements are assessed according to the specific order and destination.
11. How do I choose between DIY Cube and MO House?
Choose DIY Cube if you're looking for a modern timber backyard room supplied as a flat-packed structure for on-site assembly.
Choose MO House if you're looking for a more complete modular building with insulated construction and assembled delivery.
Within each collection, you can then compare sizes, layouts, specifications, and available options to find the best fit for your property.
