Common Interior Design Terms [& What They Mean]
When I was just getting started as a New York City interior designer, I was horrified to see the blank stares on the faces of my clients while I was waxing poetically about the perfect Schluter or the ideal flitch. It didn’t take me long to realize that if I wanted projects to run smoothly, my clients and I had to be on the same page right from the start.
So I began, right at the beginning of a project, to provide a glossary of the common interior design words and terms I’d be using during our conversations. This practice has proven to be a lifesaver.
So, if you’re working with (or plant to work with) an interior designer anytime soon, I recommend that you bookmark this page so you can refer back to it during your project. It’s not only very handy; it will also make you look very well versed in interior design!
Common Interior Design Terms [& What They Mean]
Schluter
A Schluter strip creates a transition between a tiled floor and the wall. It serves to protect the edge of tiles from being chipped or cracked. The most well-known company that produces Sschluters is, not surprisingly, Schluter Systems. Although many manufacturers make this product, interior designers call them all Schluters (similar to when someone asks for a Kleenex what she really wants is just a tissue.

Lead Time
Lead times are a measure of the amount of time that elapses between initiating a process and completing that process. Examples include the time it takes to fabricate cabinetry, build/upholstery and ship furniture, and the manufacturing time to make custom carpet and area rugs. We always identify long lead-time items early on because they can affect the critical path of a project.
Com And Col
The acronym COM stands for Customer’s Own Material. COL stands for Customer’s Own Leather. Furniture manufacturers use these terms to let interior designers know that they will accept nearly any fabric and apply it to any of their pieces.
Mitered
The term mitered describes the process of joining together two pieces of material, such as wood or glass, that have been cut at angles to form mitered corners. Material that is cut this way, at a 45-degree angle, form beautiful, elegant (and snug) 90-degree corners.

Elevation
Despite being one of the most frequently used terms in interior design and architecture, the word elevation is often misunderstood. An elevation is a simply a drawing that illustrates the front or side of a room or building. Often confused with a floor plan, which shows a space from above (as if you are looking down on the room from the ceiling) an elevation gives you the opportunity to see everything from many different viewpoints.

RCP – Reflected Ceiling Plan
An RCP is a drawing that shows items located on the ceiling of a room or space. Drawn to display a view of the ceiling as if it was reflected onto a mirror, a reflected ceiling plan is a very handy tool to show clients what their finished ceiling will look like.

CFA – Cutting For Approval
A CFA is a small snippet of fabric from a bolt that has been reserved for a project. It serves as the confirmation of that the fabric pattern and color is consistent. When matching colors for a client we must often purchase fabric from different bolts, especially when we are re-ordering material. We’ll ask for a cutting from the bolt before the fabric is shipped. A CFA ensures consistency particularly when the design requires a large quantity of material.
Ogee Edge
Although ogee may sound like a surfing maneuver, it’s a very common interior design term having to do with countertops. Ogee edge refers to a concave arc that flows into a convex arch. Ogee edges, not to be confused with bullnose edges, are frequently used in traditional kitchen designs.

Punch List
A punch list is a document that contains all the tasks that must be addressed before the project is deemed complete and our clients can move in. Commonly the punch list will include things like minor repairs to finishes, cleanup, and outstanding minor installations that are not part of the construction scope.
Trompe L’Oeil
Trompe L’Oeil is a French term that means “deceive the eye”. It is an art technique that’s meant to create an optical illusion. Objects depicted in trompe l’oeil appear three-dimensional when in reality they are rendered on a flat surface, such as a wall.

Buillon
Bullion is decorative fringe comprised of twisted fibers that are generally in longer in length than average fringe – sometimes as long as 12”. Bullion adds drama to furniture and is often affixed to the bottom apron of sofas and chairs. You’ve likely noticed bullion on the bottom edge of theatrical curtains, too.

Rendering & Sketches
A rendering is a highly detailed, three-dimensional view of a room, an interior, or a façade. People often confuse renderings and sketches. But a sketch is quite different. It’s usually rough and hand-drawn, with a minimal amount of detail.


Section
A section is a drawing that symbolizes a “cut through” image of what has been designed. It reveals the construction methods and material types used in the design.

Flitch
A flitch is a very thin piece of wood veneer sliced from the trunk of a tree. It is often used to finish exposed sides of cabinetry and millwork.

My Favorite Interior Design Services
Our core obsession, lobby interior design, is just one of several primary interior design services here at Sygrove Associates Design Group. In fact, we provide a quite wide variety of interior design services. In addition to our noted work in high-end apartment, condo and coop buildings, our capabilities include corporate offices and family homes, as well (see below).
According to the National Interior Design Association (IIDA), “Throughout the…the creative process, designers are constantly defining themselves and redefining their work.” I like to think of my team as versatile method actors being constantly exposed to new challenges that sharpen our ability to capture the emotional appeal and artistic expression of each project we undertake.
I’d like to share three projects with you to demonstrate what I mean: a chic lobby redo on the Upper East Side, a park-inspired hallway total update on Central Park West, and a stately family home in Scarsdale. All stay true to our mission of delivering interior design services that satisfy our clients’ aesthetic desires and also, stand the test of time.
Three of Our Favorite Interior Design Services
Lobby Interior Design – 14 E. 90th Street
Doesn’t this space make you feel like an aspiring urban hot shot? The owners wanted us to freshen-up their pre-war lobby so that it could be more appealing to a younger professionals and families without losing the pre-war charm. This required us to introduce elements into the space that are just a sliver on this side of edgy, but are chic and elegant, as well. This beautiful space today is the total opposite of stodgy.
What I love about this lobby is the delicate balance of artwork and accessories. Stylized butterflies and classical landscape plans give way to hand-colored architectural prints arranged in such a way that they look like mosaics. The accessories such as lamps and furniture are like precious jewels in perfect settings.
I loved being involved in every one of our interior design projects, and this one really stands out.
Hallway Interior Design – 400 Central Park West
What a delight to live on Central Park West across from the verdant environment in Manhattan. The design committee asked us if we could come up with a way to integrate the lushness of the park into this hallway interior design project. We were thrilled with the challenge!
First, we designed a gorgeous carpet that features a stylized branch pattern. It looks ultra luxurious yet it is manufactured in such a way that it repels dirt and mud (and there’s lots of dirt and mud when you live so close to the park. The wall covering, despite looking like organic linen, is hard wearing and durable, too.
Here’s the piece de resistance: In order to keep the long hallways from feeling so endless and bleak, we created twig-inspired wall murals at each end. Having artwork at the end of each corridor creates the feeling of “something to look forward to” as people walk down the hall.
I’m sure you can appreciate why this hallway redo is one of our favorite interior design projects.
Residential Interior Design (Scarsdale Residence)
As a mom and an interior designer, I can appreciate why some parents struggle with how to make their home as comfy and child-friendly as possible, but luxurious as well. If you think that child friendly and luxurious can co-exist, think again!
In this interior design project we started with a typical Scarsdale Tudor void of most of its Tudor interior elements, and went on to reintroduce period-inspired details such as a plaster ceiling, stone and wood flooring, and wall moldings throughout. Our choice of color palette fosters a light, bright, airy and super comfortable home. This living room, one of my favorite interior design projects to date, was also one of our most challenging because the owners have a lot of kids!
And with kids come sticky fingers, dirty sneakers, spills, and more. But my clients wanted a light neutral color scheme. Quite a conundrum, right? Wrong!
During my career of as a lobby interior designer, I have had this challenge many times before and I’ve become an expert on sourcing luxury materials that are soil-resistant, durable, long lasting, yet look and feel luxurious.
If you cringe when you imagine a bunch of toddlers climbing all over the incredible furniture in this irresistible living room, don’t. All of the sumptuous mohair, velvets and nappy carpets are, believe it or not, child-resistant! The luscious palette of taupes, creams, and aqua…creates a sophisticated living room for entertaining and the durability of the materials gives the family a comfy space they don’t have to worry about ruining.
I love my job. My firm is so blessed to be able to provide interior design services that make our clients happy an enable us to explore the limits of our creativity and experience. I’m fired up every morning to tackle the next adventure.
Let’s Make Beautiful Spaces Together.
