This House Comes in a Kit
Like all Avrame houses, this house comes in a construction kit.
The content of the kit can be configured according to your wishes, allowing you to source materials locally to save money on transport.
Every house shipped by Avrame kit will contain the “Structural Kit“.
The “Interior Kit” and “Exterior Kit” can be added to your order and shipped to your construction site in one single delivery.
We do ship worldwide.

A flexible solution
Building your new house with a house kit puts you in control of every little detail.
This way, not only you get to choose how your house will look and feel like, but you also can save a considerable amount of money.
How?
By deciding which parts of the house you'll buy locally and which ones you want to have ship to you by Avrame.
To help you choose, we divided our house kits into three main components:
- Structural kit;
- Exterior Kit (optional but recommended);
- Interior Kit (optional but recommended).
You can start configuring your house by customizing each of the 3 components of the kit (our team will help you with that).
Here are the details about each component of the house kit...
The Structural Kit
The structural kit is the basic component of all Avrame's house kits, therefore it is included in every order.
Avrame’s structural kit includes the A-frame structure of the house and everything you need to build a sturdy and reliable framework for your dream home.

All the beams in the kit are pre-cut in Avrame's factory, so that you can start the assembly immediately and you will have minimal waste of material on your construction site.
Building with one of pre-cut kits saves a considerable amount of time.
The A-frame structure of the house will be up in just a few days and can be assembled by a crew of just 2 man!
For the structural kit we use stress graded timber (C24 - specifically designed for trusses), cut to measure with precision machines, and packed for you in weather resistant packages.
To ensure robust connections and seamless assembly, Avrame’s structural kit includes custom hardware, steel plates, and connectors. These high-quality components guarantee the stability and durability of your home.
The kit also includes important elements such as dormers, pressure-treated and deep-impregnated sill plates, and a ladder structure with a handrail, to facilitate safe and convenient access to different levels of your A-frame house.
The framing of the front and back walls and the framing of the extended eaves are included in this kit.
To ensure optimal energy efficiency and weather protection, Avrame includes a weather barrier in the kit (Tyvek). This barrier is engineered to offer protection from the outside elements, keeping the insulation material safe and dry all year round.
The structural kit comes with detailed permit drawings and clear assembly instructions, guiding you through each step of the construction journey.
Included in the Structural Kit:
- Permit drawings (views, plans, cross section, elevations, foundation sketch, information about main joists)
- Structure assembly instructions
- Precision engineered lumber for trusses
- Custom hardware/steel plates/connectors
- Dormer
- Treated sill plates
- Ladder structure and handrail
- Engineered wood panels for ground floor element (OSB3 12mm)
- Engineered wood panels for underlayment of 1st and 2nd floor (OSB3 22mm)
- Engineered wood panels for roof sheathing (OSB3 12mm)
- Front and back walls framing
- Extended eaves framing
- Building wrap (Tyvek)
The Exterior Kit
The exterior kit contains all the materials to finish the exterior of the house, making it weatherproof and giving it its stunning look.
You can avoid ordering the exterior kit and source its materials locally. While this makes sense in some cases, over 90% of our customers includes the exterior kit in their order.

The main items in the exterior kit are: the roof cover, the windows and exterior doors, the exterior cladding.
The Roof
Metal is the ideal material to use as roof cover in A-frame houses.
A good metal roof cover requires little maintenance. Due to the steep slope of the roof, the rain will simply wash off the dirt that accumulates naturally on the roof.

The roof cover we supply is "Ruukki Classic C".
Ruukki is a Scandinavian company that has produced roofs for over 50 years.
Their industry-leading warranty covers their product for 50 years against structural defects and for 20 years against aesthetical issues.
Ruuki also offers a variety of colors to choose from!
The Windows
Windows are one of the most important (and expensive) components of any good house.
This is because they have the duty to keep the outside world out while allowing light to reach the interiors.
Good windows must be durable, functional, weathertight, and have good energy performance.
Avrame's standard exterior kit comes with high-quality PVC windows.

The PVC profile used in these windows and terrace doors have 6 chambers. This lightweight profile guarantees a superior energy performance and good functionality of the windows.
The windows are equipped with 3-layer tempered glass and their average thermal transmittance is around 0.83 W/(m²K).
Optionally, you can upgrade the kit to wooden windows. The energy performance of wooden windows is about the same as the PVC ones, but the cost is about 3 times more.
The Exterior Cladding
The cladding material protect the exposed parts of the house (front and back walls + roof eaves) from the elements.
The cladding material must be durable and require as little maintenance as possible.

In the exterior cladding provided in the kit is made of pine and it comes with a CE certification (required in EU).
Optionally, if the location of the building has a very harsh UV exposure, we also offer thermo-treated exterior cladding.
All the cladding material is delivered uncut and shall be cut to measure on site.
Included in the Exterior Kit:
- Roofing material (metal roof, Ruukki Classic C with fixings)
- Battens for roof structure (32x100mm)
- PVC windows and terrace doors (U=1,2 or better with 3- layer glass)
- External wooden doors (half glass/full glass)
- Exterior cladding
- Soffit and gable boards + eaves
The Interior Kit
The interior kit contains the materials necessary to finish the house inside and to make it fully functional.
You can avoid ordering the interior kit, but most of our customers decide to include it in their delivery because of the considerable savings (compared to sourcing stairs and cladding locally).

The Interior walls
In Avrame's A-frame houses, the interior walls don't have any structural function (all the loads are carried by the A-frame trusses).
This means that the layout of the rooms is flexible and you can rearrange the position of the walls as you like, before ordering the house kit.
After the order, we'll cut the material for the interior walls to the exact measure necessary for the assembly.
All the wooden parts used in the interior walls are stress-graded C24, and come with CE certification (required in EU).
The Interior Doors
In the interior kit we supply al the interior doors.
Every door comes with its own frame.
Our standard doors are made of medium-density fiberboard, white color.
The Interior Cladding
If you wish your house to have wooden interiors, then you can benefit from ordering the interior material for the interior cladding directly from Avrame.
Some customers prefer finishing the interior of the house with gypsum boards. In that case, we recommend sourcing the gypsum boards locally (it is usually cheaper).

For the interior cladding we use top quality spruce material grown locally (profile STP0, size 14x121x111mm).
The Stairs
At the heart of every home is the journey from one level to the next.
Recognizing this, we bring you reliable stairs and ladders that seamlessly blend with your space.
Teaming up with Aru Grupp LLC from Estonia — a dedicated manufacturer with over 20 years of experience — we offer FSC certified wood products built to accompany you for years to come.
Our premium staris are usually more affordable than a comparable product bought in your area. This allows you to save a considerable amount of money!
Included in the Interior Kit:
- Interior walls structure (45x95mm)
- Interior doors with door frames (MDF 800x2100mm)
- Painted Interior Cladding
- Wooden stairs
