Lighting shapes how a home looks, feels, and works. It can make a room feel warm, bright, calm, and comfortable.

A beautiful room should also be easy to use. Good design is not only about color, furniture, or finishes. It is also about how people move through a space and how each area supports daily life.

A bathroom should feel restorative, well planned, and effortless to use. It is one of the most personal rooms in the home, yet it also has to meet practical needs every day. Strong bathroom design balances those two expectations. It creates a setting that feels refined, but it also supports storage, movement, maintenance, lighting, and comfort.

The kitchen is one of the most important spaces in a home. It is where families cook, gather, and spend time together. A well-designed kitchen should support daily routines while still feeling comfortable and inviting.

Many homeowners compare custom interior design vs. pre-designed spaces when planning a home. Both can look beautiful. But the process is different. One builds a plan for you. The other uses a plan that already exists.

Understanding how to design a timeless home that won’t feel dated requires a shift in mindset. Timeless design is not about avoiding style or playing it safe. Timeless design focuses on making smart choices that stay meaningful as people’s preferences, trends, and life situations evolve.

Yes. From our studios in Silver Spring and Bethesda, Interiors By Design works with clients across Maryland and the greater Washington, DC region—including Potomac, Chevy Chase, Rockville, Columbia, and Baltimore—on residential, commercial, and multi-family projects, with select work nationwide.
Every project moves from an initial consultation, through concept and design, into procurement and FF&E (furniture, fixtures & equipment), and finishes with a white-glove installation and styling. We manage sourcing, warehousing, and delivery so the whole project is handled for you.
Investment varies with the scope, square footage, and level of customization of each project. Every engagement begins with a consultation, after which we provide a clear, itemised proposal so you know exactly what your project involves before any work begins.
Timelines depend on scope and product lead times—a single room moves considerably faster than a whole-home design. We map a realistic schedule for you during the design phase and manage procurement and delivery against it, so you always know what happens next.

Absolutely. We regularly build a room around heirloom and existing pieces, blending what you love with new, trade-only sourcing and custom furnishings so the space feels collected rather than staged.
