Melissa
My house has been transformed into my dream home! Mariia has a knack for interior design. I loved when she gave me enhancements by simply shifting furniture/plants around. It was instantaneous elevation to my house! She works really hard on giving you options within your budget — she never compromises quality. She is extremely affordable, professional, personable, and most importantly, knowledgeable in interior design. Loved working with her, but most importantly love my new dream home! Cannot thank her enough, I finally feel comfort in my own home. More...

Which interior design styles can you cater for?
I love creating spaces that reflect your taste and lifestyle. My background is rooted in timeless, livable design — from modern transitional and California casual, to coastal, contemporary, and classic European-inspired interiors. I also enjoy blending styles to make something unique, whether that’s adding a touch of modern edge to a traditional home, or layering textures for a cozy, lived-in feel.
What do you love most about your job?
What I love most is seeing a house turn into someone’s home. Every family has their own story, style, and rhythm — and I get to translate that into a space that feels both beautiful and truly livable. The best moment is when a client walks in and says, “This feels like us.” That joy and connection is why I do what I do.
What inspired you to start your own business?
I’ve always been drawn to creating spaces that feel welcoming and beautiful, and starting my own studio gave me the freedom to bring that vision to life in a more personal way. I wanted to work closely with families and homeowners, really listening to their stories and helping them create a home that feels like theirs. Building my business has allowed me to share my creativity while also balancing my role as a new mom — both parts of my life inspire me every day.
Why should our clients choose you?
Because I treat every project as if it were my own home. My approach is warm, collaborative, and detail-oriented — I listen carefully, respect budgets, and guide clients through the process so it feels exciting, not overwhelming. I blend creativity with practicality, making sure your space looks beautiful but also works seamlessly for everyday life. Clients choose me because they feel truly cared for, and because together we create homes that feel both elevated and deeply personal.
Can you provide your services online or remotely? If so, please add details.
Yes! I offer full virtual design services for clients who are not local or prefer to work remotely. With online consultations, digital mood boards, 3D renderings, floor plans, and curated shopping lists, you can see your space come together from anywhere. I guide you step by step — from initial concept to final styling — so you feel supported and confident in bringing the design to life on your own or with local installers.
What changes have you made to keep your customers safe from Covid-19?
Client comfort and safety are very important to me. During in-person visits, I follow health precautions such as keeping a safe distance, sanitizing hands and samples, and wearing a mask if requested. I also offer fully remote/online design services so clients can work with me from the comfort of their own home if they prefer.
