«In August of this year, the Tallinn City Property Department announced an idea competition for environmentally friendly solutions for the Päikene and Pääsupesa kindergartens in North Tallinn, which would allow factory-produced wooden modules to be flexibly adapted to the needs of the kindergarten. The solution for the new kindergarten buildings is created in the MusterMaja 369 system developed at the Estonian Academy of Arts, with the aim of contributing to the green transformation in construction.»

«A nail gun in a man's hand is a common sight in timber construction. Except when building a circular economy-compliant building, where no nails can be used because the materials must be connected in a way that allows the building to be dismantled into its original components and the pieces can be reused without much effort in another location, such as building a shed, house, or pavilion.»

«The Elektrilevi training center will be the first 100% modular, wooden, and high-quality architectural and technical training center in Estonia. It will be assembled from industrially produced components and can be easily dismantled, maintained, expanded, or relocated as needed - something completely new in design and construction for Estonia. The building designed in the significantly updated MusterMaja system developed at the Estonian Academy of Arts demonstrates how future school buildings can be constructed to enrich the local community and not become an administrative burden, but rather keep up with the needs of the client.»

Our process

Step 1: Start

Begin by completing the questionnaire below to help us understand your preferences and requirements.
Questionnaire

Step 2: Design Development

We'll craft a unique architectural and spatial design tailored to your specifications

Step 3: Quotation and Customization

We'll secure a quotation from a manufacturing partner for your project. We're happy to adjust the design to meet your needs — the first customization is complimentary

Step 4: Preliminary Design

For structures exceeding 20 m², we may need to develop a preliminary design, available for an additional fee

Step 5: Site Preparation

Site preparation is managed as a distinct project.
The minimum foundational requirement typically includes screw piles.

Step 6: Installation

The final step involves the manufacturing, transportation, and assembly of your building on-site

QUESTIONS / ANSWERS

Cost

Q: Is a MusterMaja more expensive than a traditional wooden house?

A: MusterMaja homes offer significant savings by optimizing construction time, labor, and materials. They are competitively priced compared to traditional wooden houses, and the lifecycle cost of the building is expected to be 2 times lower than that of a regular wooden house.

Customization

Q: How customizable is a MusterMaja home?

A: Your MusterMaja home can be tailored extensively to fit personal preferences and needs within a 18-59 m² range, ensuring a unique home that can grow with you.

Durability and Maintenance

Q: How do MusterMaja homes compare in durability to traditional buildings? What about maintenance?

A: Constructed in controlled factory conditions, MusterMaja homes are designed to outlast traditional buildings. While regular maintenance is comparable, our homes enjoy a longer lifespan due to their superior construction quality, since they are not built under the rain, wind, and snow.

Environmental Impact

Q: Can you elaborate on the environmental advantages of MusterMaja homes? How sustainable are the materials used, and what makes this system truly circular in terms of waste reduction?

A: MusterMaja is committed to environmental excellence, using recyclable and low-emission materials. Our design promotes a circular economy by allowing for easy disassembly, replacement and reuse of components, significantly reducing waste.

Permits and Regulations

Q: How does the permit process for a MusterMaja construction compare to traditional homes?

A: For MusterMaja homes, especially those under 60 m², the permit process is streamlined, often requiring just a construction notice. This makes the journey from design to a turnkey home as short as 2-3 months.

Installation Process

Q: What does the installation process involve? What is required for site preparation, and how are utilities connected?

A: Installation begins with site preparation, including connecting water and sewage. For many sites, simply installing screw piles is sufficient for a foundation.

Flexibility of Relocation

Q: Can a MusterMaja home be relocated? Is it feasible?

A: Yes, designed for flexibility, MusterMaja homes can be easily disassembled and relocated, offering a sustainable option for changing locations with minimal logistical hassle.

Resale Value

Q: What's the resale value of a MusterMaja home?

A: MusterMaja homes are expected to maintain excellent resale value, thanks to their sustainability and adaptability. As material and construction costs rise, they represent a smart investment for the future.

Energy Efficiency

Q: Are MusterMaja homes energy-efficient?

A: Designed for optimal energy use, MusterMaja homes can easily be upgraded to meet Class A energy efficiency standards, supporting the use of renewable energy sources like solar panels for a greener living.
