The Guide: Interior Designers in Warren, Watchung and Green Brook, NJ

How We Selected These Designers

This guide covers Warren, Watchung and Green Brook.

A design studio appears in the first table if it is a working interior design practice with completed residential projects and either a studio, showroom or office in one of those towns or a website of its own that says it serves one of them or the county they sit in.

Both halves of that are things you can check yourself. The practice is the work shown on its own website. The service area is what that website says.

That is a test, not a judgment, and it is the only route onto this page. Three studios meet it. They are listed alphabetically.

The second table lists studios that met the same criteria and have their premises in another town (listed with the town their own site gives).

About This Guide

This guide is produced by Garden State Circle. Designers appear here because they meet the criteria described above — a working design practice with completed residential projects and a studio, showroom or office in the towns this guide covers, or a website of its own that says it serves them. That is a test, not a judgment, and it is the only route onto this page. No designer can pay to be included in this guide, to be listed higher, or to change what the comparison table says about it. Designers are listed alphabetically, and every detail in the table was verified against each firm’s own website, or against documentation the firm supplied, in September 2026.

Everything under the heading that begins this guide is governed by the rules above, on every guide we publish. Where a sponsor’s message appears above that heading, it is paid for and labelled, and it buys nothing in the guide. Garden State Circle is supported by the businesses that participate in it. Participation pays for our ongoing work: keeping a business’s entry accurate, re-checking its record, and publishing a page of its own details that the business maintains. There is no paid placement in this guide. Participation does not buy a place here, a position here, or anything the comparison table says.

Garden State Circle is published in New Jersey by Tiffany and Jake Slowinski and covers Warren, Watchung and Green Brook. Contact the publisher at jake@gardenstatecircle.com. How every guide is made, in one place: how every guide is made.

Common Questions

What is the difference between an interior designer and a decorator in New Jersey?

New Jersey certifies interior designers. It does not license them. A designer who has passed the NCIDQ examination and registered with the state may use the title Certified Interior Designer, or CID. The certification is voluntary, and many experienced designers in this market do not hold it, so its absence is not a mark against a firm. What it tells you is that a designer has passed a national examination covering building systems, codes and construction documents.

The distinction between certification and licensure matters more in some states than others. New Jersey protects the title. A handful of states, Georgia among them, go further and license interior designers to sign and seal drawings for permitting, which is a different level of authority than New Jersey grants.

Do I call a builder, an interior designer, or an architect first?

It depends on what the project changes. Work that moves load bearing walls, adds structure or changes the footprint of the house usually starts with an architect, though the strongest outcomes tend to come from projects where a designer and an architect are involved together from the beginning rather than in sequence.

Non load bearing or cosmetic work, and kitchen or bath renovations, more often start with a designer, because the decisions that drive the cost are made in the planning, not on site. A contractor prices a plan more accurately than a conversation, which is the argument for planning first either way.

What does an interior designer charge?

Designers in this market work on flat fees, hourly rates, a percentage of the construction budget, or cost-plus on furnishings, and most do not publish their rates. The comparison table above shows which firms publish a consultation fee and which do not. Ask for the fee structure in the first phone call. It is a fair question and any designer will answer it.

Should I tell a designer my budget?

Yes. A designer who does not know the budget is guessing, and the expensive corrections happen later, once orders are placed and drawings are filed. Naming a real number early is what lets a designer show you options at that number instead of above it.

Do I need to visit a showroom?

Not necessarily, but it changes the conversation. Several firms in this guide keep a showroom you can walk into, which is noted in the table. Bringing plans to a first showroom visit is the fastest way to find out whether a designer is the right fit for the project.

Where a firm does not publish something, this guide says so rather than guessing.
