Our Approach

At Lousso Designs, we offer two core services: Custom Furniture — Nationwide and Upholstery — Massachusetts Only.

Custom builds include nationwide threshold delivery, with white-glove delivery & installation available in major U.S. cities.

Measurements made easy: we provide step-by-step guides, and if you can’t measure yourself, we can arrange help so your specs are confirmed before production. From specs to delivery and installation, we guide you every step of the way.

40+ Years of Excellence

Our Story

At Lousso Designs, our story began in the 1980s when Kostas Konstantinidis, a skilled craftsman from Athens, arrived in Boston with nothing but a staple puller and a dream. After years of perfecting his craft, he opened his first upholstery shop in Newton, Massachusetts, in 1982. A journey filled with challenges, triumphs, and the true embodiment of the American Dream, through hard work and dedication, Lousso Designs became a respected name in the interior design industry.

Today, Kostas works alongside his son, Yanni, who is blending traditional craftsmanship with innovative technology. Together, they are redefining the future of Lousso Designs.
