"I couldn't have expected a better service, and that's after using several engineers in the tri-state for past work. This engineer also goes above and beyond. He is meticulous, honest and very responsive. He was truly a pleasure to deal with. I will absolutely be using him again, and I wholeheartedly recommend him.

"Our experience with Preservation Design Group was first rate all the way. From start to finish, the architect was responsive, attentive, creative and professional. We were impressed by Dan Koplowitz's attention to detail and willingness to listen to what we wanted to achieve with the project, which added over 1500 square feet, relocated bathrooms and renovated and enlarged the kitchen. Dan worked diligently to meld the exisiting house with the new and provided plans that our town approved without requiring modifications and the building dept. is quite strict. The builder Dan recommended was excellent and they worked well as a team."

Architects FAQs, answered by experts

Some architects include interior design in their portfolio of offerings, while some architectural firms employ interior designers to handle that aspect of home building projects or refer clients to interior designers they’ve worked with in the past. Ask a local architect whether they offer interior design services as well.

You can draw your own house plans using three-dimensional modeling software, but in most cases, you’ll need an architect to draw up the final plans. Architects understand local building regulations and requirements, so their plans will be necessary for getting permits approved, and they’ll also ensure your home is structurally sound. DIY house plans can be a good place to start to help visualize your project, but you should always defer to a professional before trying to proceed with the project.

Open floor plans can come with drawbacks—mainly the lack of privacy and noise dampening. Walls act as an important barrier for traveling sounds, meaning in an open floor plan you could hear your dishwasher running while sitting in your living room. Storage limitations and separation of activities (for example, keeping the kid’s playroom away from the dining room) are other reasons some homeowners are opting out of an open floor plan.

While towers and turrets are frequently present in Queen Anne-style houses, these design elements are not necessary for a home to be considered a Queen Anne. Turrets and towers add visual interest and unique interior spaces, but many Queen Anne homes do not contain these features. 

As with most large-scale home renovation projects, you’ll need an architect to map out the exact layout and specs of your above-garage room, which is required in many municipalities. Some general contractors will serve as your architect, or they may bring on a residential architect to assist with the plans.
