At DSI we are passionate and enthusiastic about making the vision of your dream home a reality. We are inspired by our ever changing surroundings, and with every design we create alongside our clients we create clusters of beauty in every room, in every home, and for every family.


Tiziana is the proud owner of DSI. She is passionate and enthusiastic about making the vision of your dream home a reality. Located in the heart of Smithtown NY, she is constantly inspired by the styles and designs that are all around.
The goal at each meeting with our clients is to make them feel heard, to impart knowledge and a sense of lifestyle which is all your own. Clients are blown away as we conceptualize your ideas for design and styling.
We look forward to making your home a place that you truly love to live in.


Mindful design is the decision making process for the benefit of the client using our services.
Every client has an individual style.
Every room has its individual purpose.
Finding the synergies between the two is a designer's primary responsibility. Clients don't have to know the names of each style type; they simply need to focus on how they feel. What colors, textures, sizes make them feel comfortable and happy in that space.
At DSI, we are responsible for finding your true style, and not imposing our style on you.
We listen to you. And deliver your style to your home.
