Residential Interior Design By The McMullin Design Group In NJ


Whether you are looking for a color consultation for a small cottage or an extensive makeover for a grand estate, the team at MDG will manage the process of translating your vision from conceptual design to reality. We are experts at coordinating both new construction and renovation projects. Our top-down process will guide you through every step of your project. From space planning and material specification, to kitchen and bath design, custom millwork, furnishings and window treatments; no detail will be overlooked. Our unique blend of project management skills and design prowess are engineered to allow you to focus on the outcome while we manage the day-to-day aspects of the project.

Some of our clients are weekend warriors who just need some guidance on how to complete the work themselves, while others have more extensive obligations and are looking for a team to manage the project for them. Most clients fall somewhere in between. We pride ourselves in being able to help you achieve your vision in the way that best fits your lifestyle.
