WHY LETOON ARCHITECTURE?

Experience

Experience & Expert Staff

We were not just raised on theory, but on Turkey’s most challenging restoration scaffolding. With our experienced staff, we analyze every project as a dataset; we approach structural problems not by rote, but with engineering discipline. Experience the difference of working with an expert team for the most accurate and permanent results in your projects.

Material Quality

Superior Material Quality and Building Physics Compatibility

“The longevity of a structure depends not only on the quality of the material used but also on how compatible it is with the nature of that structure. As LETOON, we provide the highest level of protection without preventing structures from breathing, thanks to the high-performance, mineral-based, and ecological products we offer.” Mineral-Based Protection: Instead of creating synthetic layers foreign to the structure, we use mineral technologies that integrate with the surface. Structural Health and Aesthetics: While protecting the health of your structures (moisture, corrosion, salinization), we provide a matte and natural aesthetic appearance that defies time. Respect for Nature and Resources: We keep our promise to leave a more livable world to future generations with contents that go through sustainable production processes, have a low carbon footprint, and are harmless to human health.

R&D

Domestic R&D Power: BAUTERA & ECOTERA

We have combined world-class technology with the needs of the local field. With our innovative products manufactured in Turkey, we offer the flexibility to develop project-specific materials while reducing foreign dependency.

Improvement

Continuous Improvement and Knowledge Sharing

“While technology changes rapidly, we believe that the best solution is only possible with up-to-date knowledge. As LETOON, we do not keep our 20 years of technical know-how to ourselves; we grow together with our stakeholders by creating a ‘knowledge ecosystem’.” LETOON Academy and Field Training: We set the standards for new generation application techniques with on-site field training and interactive online seminars organized for our applicators and business partners. Expertise Support: We increase the knowledge accumulation of our teams and solution partners at every stage of the project, and provide up-to-date and scientific guidance against the most complex problems in the field with our technical staff.

Academy

Training and Knowledge Sharing: LETOON Academy

“We believe that knowledge gains value as it is shared and that the sector will only rise with qualified expertise. Under the roof of LETOON Academy, we transform our 20 years of technical accumulation into an educational discipline and transfer it to all our stakeholders.” From Theory to Practice: We do not just explain restoration and building protection standards; we maximize the technical competence of our applicators with both our online seminars on digital platforms and our field training on the scaffolding. Restoration Awareness: We build a bridge between architects, engineers, and craftsmen for the dissemination of correct intervention methods; we bring together academic precision and field practice in the protection of cultural heritage. Continuous Consultancy: We support our training processes with certified programs and stand by our business partners as a ‘constantly open information line’ against the technical difficulties they encounter in their projects. “We are building the future of the sector together with professionals who bring the right knowledge to the right surface.”

Eco-Friendly

Sustainable Solutions

We do not forget our debt to future generations. With our mineral-based, breathable, and environmentally friendly products, we both protect building physics and produce nature-respecting projects with low carbon footprints.

System

System-Oriented “Holistic Solution” Approach

We do not just cover the problem; we solve it at the source. With our methodology consisting of Cleaning → Stabilization → Protection steps, we maximize the building life by offering complementary “system solutions” instead of a singular product.

Field Support

Technical Consultancy and “Field Side-by-Side” Support

For us, the job does not end with product delivery. We are a solution partner who is with you at every moment of the project with our applicator-specific guides, on-site technical supervision, and solution-oriented service network.

Fast Result

Fast and Effective Results: Operational Efficiency

“With the awareness that time is the most valuable resource, we rapidly bring high performance to your projects. With our advanced application techniques and technological material portfolio, we produce permanent results in the shortest time without compromising quality.” Time and Cost Optimization: Thanks to correct diagnosis and correct product matching, we eliminate unnecessary interventions; providing maximum advantage in both your work schedule and budget. High-Performance Application: With our modern equipment and methodologies, we complete even the most complex restoration and protection processes within targeted times and at high standards. Solution-Oriented Service: By giving quick reflexes to dynamic needs encountered during the project, we ensure the workflow continues uninterrupted and optimize the return on investment period.

Reference

Reference and Trust: Our Signature is Our Guarantee

“Our presence in the sector for over 20 years consists not only of completed projects but also of the unshakable bonds of trust we have built. From Turkey’s most symbolic public buildings to thousands-of-years-old historical heritages and modern architectural masterpieces, we carry the reliability of the LETOON signature at every point.” Versatile Experience: We blend our restoration sensitivity in monumental structures with the protection needs of modern industrial facilities and prestigious residential projects. Proven Success: Our wide reference network is the most concrete proof that the solutions we offer maintain their performance even after years, and that we increase the resistance of structures against time. Sustainable Partnership: For us, every project is not an end, but the beginning of a new journey of trust. With the long-term collaborations we have established with public institutions, author architects, and our global solution partners, we continue to be the most reliable harbor of the sector.

Why Don't We Quote Over the Phone?

The LETOON ARCHITECTURE Approach

At LETOON ARCHITECTURE, we do not approach any project with "memorized" or "standard" cost tables. This stance is not to hide the price, but rather our responsibility to offer you an accurate and sustainable solution.

Every Project Has a "Fingerprint"

The surface characteristics determine the price, not just the square meters:

  • Material structure (Concrete, Plaster, etc.)
  • Level of surface deterioration
  • Past application errors

Transparent Analysis, Precise Results

Approximate prices given over the phone are often misleading and lead to "extra costs".

  • On-Site Analysis: We see the need.
  • Technical Strategy: We create root solutions.
  • Net Offer: No surprise costs.

System Solution, Not Just a Product

We don't just sell materials. We offer an integrated system with proper surface preparation and appropriate protection technology.
