FUNCTIONAL LAYOUT:
Barn House Optimum Long is an excellent proposal for a house project designed for narrow plots. It’s a single-story house, economical to build, optimized in terms of functions, structure, and energy efficiency. It features a simple, clear functional layout.
From the front side of the plot, a convenient two-car garage is designed, connected to the residential building through a utility room with a laundry area. The main entrance to the building, however, is designed on the side wall. This solution leads us directly into the vestibule, which is directly connected to the living area – the living room with the kitchen, which beautifully opens up to the garden through large windows. Upon entering such a high-ceilinged space, open to the roof structure, we will certainly make an impression on any visitor.
The interior is planned along a single communication axis, ending with the living room and dining area, along with an open, truly spacious kitchen. Large windows illuminate the space, visually enlarging it and providing a visual connection with the plot. In the living room, two large windows are designed, one of which, sliding type, leads us directly to the terrace, partially covered.
From the living room, stairs lead to the attic (the attic is unused, but can be adapted for residential purposes). In case of no attic adaptation, it is easy to dispense with the stairs, gaining square meters in the living room or bedrooms.
In the private part of the building, there are three bedrooms, including one with a bathroom. In addition, there is a shared bathroom and a room that can serve as an office or guest room.
BUILDING SHAPE:
This is a simple single-story house in the style of a modern barn, with a rectangular floor plan, covered by a symmetrical, double-pitched roof with a 30° slope. The building is maintained in a uniform and minimalist style. Accents in the form of awnings or eaves have been eliminated to make the building versatile, but above all, to avoid generating additional costs during construction.
The building has a very simple structural layout based on four axes, with a straightforward double-pitched roof and a wooden ceiling. This makes the house easy to build and cost-effective.
The facade of the building features white silicone plaster and dark wood, creating a visually appealing color scheme. There is the option to customize the materials to match the local context or the individual preferences of the investor.
BUILDING STANDARD AND CONSTRUCTION TECHNOLOGY
The building has been designed to an energy-efficient standard in accordance with the 2021 Technical Conditions – featuring underfloor heating, an air heat pump, and mechanical ventilation with heat recovery.
MASONRY WALLS: Two-layered construction – cellular concrete blocks + graphite polystyrene insulation; silicate partition walls.
ELEVATION: Wooden cladding, light-colored plaster.
CEILING: Wooden ceiling.
STAIRS: Wooden modular stairs.
ROOF: Standing seam metal roofing.
Additionally, the simple double-pitched roof allows for easy and aesthetically pleasing installation of photovoltaic panels (ideally on the southern or eastern/western slope).
MINIMUM PLOT DIMENSIONS:
The best positioning is with the entrance from the northern side of the plot, but entry from the eastern and western sides works well too. Below, we present various options for situating the building on the plot.
In the event of forgoing the garage, there is the possibility of siting the building on a shorter plot.
The drawing shows the minimum distances from the property boundary according to Polish building regulations. In your region, these distances may be different.
However, it is possible to request a change in technology.
If you are interested in changing technology – contact us by e-mail.
FRAME BARN HOUSE
We have the ability to easily change the construction of the house to either steel or wood frame technology.
Benefits of frame technology:
- wooden frameworks are more resistant to shocks and seismic forces than traditional masonry structures
- a more environmentally friendly solution
- shorter construction time, shorter working hours for workers
PREFABRICATED BARN HOUSE
Barn Houses Ideas collaborate with a company that specializes in manufacturing building components, like: ceilings, walls, roof, etc.- in factories and then transporting and assembling them on site.
The technology allows for a construction time reduction by half. You are able to build your barn house in 4-5 months.
Prefabricated construction is about 15-25% more expensive than comprehensive traditional construction.
What do you gain in return? Among other things:
- an ecological house made of natural materials
- quick realization of the house even in 4-5 months, and thus also immunity to unstable prices on the market
- minimal involvement in the construction – without the restriction of teams and materi
greater usable area of the building due to the smaller thickness of the walls - a house situated on a foundation slab
- guidance and advice from an experienced team
- noticeably better quality and durability of individual components.

Plan version

Standard Plan

Mirrored Plan
Plots have different shapes and entrances from different sides. To make it easier for you to adapt our warehouse plan to your plot of land, we offer you a choice between two versions of the warehouse plan: the standard plan and the mirror plan.
The most important factor in choosing between the two is the direction of the world from which the entrance is located. This determines which version of the plan will fit the most for your plot.
In the ‘Plot’ section of the product page, we provide a detailed description of our recommended entrance location. Take a look at this information and choose the variant that best suits your plot.
In addition to the option to change the building technology and construction, described in the “Construction Options” tab for each project, it is also possible to introduce additional modifications. We handle both minor changes and more advanced ones, such as modifing the layout of rooms in the house or changing the appearance of the facade.
If you are interested or have any questions regarding this, please contact us.
Describe in an email the modifications you are interested in, and we will price them individually.

The Barn House Idea is not just a blog and ready-made projects; it’s a way of thinking about construction, about choices and compromises to achieve the desired goal with full satisfaction. The Barn Project is about minimalism, functionality, simplicity, and energy efficiency, all guided by construction economics.
Our Barn House M has been inhabited for 6 years now. We didn’t expect that our construction and design efforts, which we document on the blog and through social media, would create a community around this idea. It could be said that The Barn Project is more than just projects; it’s also a forum for exchanging opinions and experiences. It’s a community that you can also be a part of.
