Gablok: the story of an insulated block

Added value: structure for self-building

Founded in 2019, Gablok offers a revolutionary insulated timber-frame construction method. Aiming to simplify construction and offer a simple, high-performance, and flat-pack timber house system, Gabriel Lakatos filed his patent in 2018.

A fan of interlocking building block toys from an early age, and involved in traditional construction for 25 years, he came up with the design for stacked insulated wooden blocks.

After many months of research and testing, the self-build house system has been validated by stability, acoustic, and energy performance consultants.

Stacking wooden blocks

We offer you the possibility of carrying out your plans using our wooden block construction method inspired by the famous interlocking building block toy. As soon as these have been completed, you will receive an assembly diagram with all the steps required to complete your stacking wooden block project.

We will guide you through the construction of your foundation slab and laying the first row of cellular blocks.

Then it’s up to you: follow your assembly plan step by step and your shell will be complete in less than a week.

I heard about Gablok completely by chance on the programme “On n’est pas des pigeons”. As a keen handyman, I was immediately won over by this concept. I’d wanted to build a garage workshop for a long time. I found THE solution: lightweight and super-insulated blocks. Very competitive prices. What more could you ask for? Once the concrete slab was installed, the 40 m² garage was built in one day.
My neighbours couldn’t believe it and neither could I. I really found a very professional and friendly team! I am convinced of the product’s quality. It will certainly satisfy many self-builders.

An innovative process that deserves to be developed! Bravo!

I think the concept is very original, it lets self-builders consider projects at reasonable prices. Well done to the designers

I’m lucky enough to have seen the evolution of the show house and an artist’s studio (my sister’s) built with Gablok, and I think it’s an ingenious, quick, and fun idea! I would recommend Gablok 1,000% based on these experiences.

I think the concept is revolutionary! We want more…
And especially with passionate and professional people like Gabriel Lakatos and his partner.

Serious company and friendly boss. Don’t hesitate!
