Our Story
We are Krešimir & Tonći – sculptors based in Zagreb, Croatia, with a shared fascination for concrete, texture, and recycled materials.
In 2018, we founded [ kutnakvadrat ] as a creative outlet to explore concrete as both a sculptural and functional medium.
Each piece is crafted with care, combining organic forms with durable materials to bring timeless character into modern spaces.

Vaša priča naša je inspiracija

Dečki su sjajni, suradljivi i profesionalni, a proizvodi jako atraktivni i sofisticirani.
Poklonila sam ih i preporučila već nekoliko puta i nastavit ću i dalje. Jedan od zanimljivijih hrvatskih dizajnerskih koncepata.
Samo naprijed!
Jelena Cvitanušić, CRO

Was sceptical at first, not knowing how they look live, but my clients love love love their products, so, now I use them for procjects as much as possible.
Vedran Berta, CRO

Sjajni proizvodi, minimalistički, a opet glamurozni. Savršeno se uklapaju u većinu interijera.
Ono što me posebno oduševilo je ažurnost tog umjetničkog dvojca kada su mi paralelno s kurirskom službom počeli slati informacije o statusu pošiljke; koje jako volim i cijenim i bili su izuzetno ljubazni u nastavnoj komunikaciji.
Dorja Sabljak, CRO

Penadnt lamps are stunning!
Exactly as pictured. These are also the most wonderful kindest shop owners to work with.
I am based in the US and have a tricky project and they coached me through the entire thing, helped me find the necessary materials, were prompt in their response, kind, willing to help and more.
I could go on.
Will use them again 110%!

Potpuno jedinstvena priča iza izuzetno funkcionalnih i estetski primamljivih proizvoda.
Ako uz to pridodaš da su Krešo i Tonći toliko predani svome poslu da im nije problem izaći u susret čak i kada je rok kratak, zbilja dobivaš cijeli paket. Njihovi se proizvodi odlično uklapaju u svaki stil uređenja, stoga tražite li statement komad koji će dati jedinstveni karakter vašem domu, ne tražite dalje!
Monika Novak, CRO

Spectacular!
Every aspect of this purchase was simply spectacular. Ongoing updates during the item’s creation. Updates during shipping from overseas, and then, the arrival. The piece is . . . yes, spectacular. It’s a true functional piece of art that is surprisingly lighter than expected, given it’s composition.
I’ll be back for sure, and will share your work with joy.
Cindy Goodwin, USA

Proizvod je i bolji nego na slici jer se uživo dobije i ta taktilna dimenzija!
Dečki su super (i) pristupačni i omogućili su mi da bez stresa imam poklon za prijateljicu iako sam se sjetio very last minute.
Vedran Grizbaher, CRO

Love my new concrete pendant lamps. The Modern Industrial Design and aesthetic is what we were looking for our home. Designers were so supportive and great communication with any of my questions.
Maria De La Cruz, USA

Gorgeous selection of planters and bowls.
Great customer service, and the brand with high sense of aesthetics reflect this small company's respect for nature and its beauty.
Kitica Kekić, CRO

Puno hvala na profesionalnosti, iznimno brzoj dostavi i prekrasnoj tegli. Oduševljeni smo Vašim proizvodima i svakako ćemo još naručivati što privatno, što eventualno u poslovne svrhe. Svako dobro želim, izvrsni ste!
Vesna Juriško, CRO

Beautiful lamp, looks great in a large bedroom that we have. Superb supplier, very responsive and keeping us updated on the production and delivery timelines.
Dominik Adamus, UK

The owners of this company were very helpful and did a great job communicating about their wonderful product!
