"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

While the Arts and Crafts movement inspired many architectural elements, the primary styles from the time include Craftsman, Tudor Revivals, bungalows, and Mission homes. You'll see elements of these styles in homes, churches, museums, and schools—particularly Country Day schools from the era.

Yes, professionals will offer tailored solutions to fit architectural and personal style preferences.

The design phase varies by project size and complexity; initial ideas can take weeks, while extensive plans may extend to months for complete detailing.

The cost to draw house plans typically ranges from $800 to $2,700, with standard blueprints averaging around $1,800. For a custom home, the cost is higher, with blueprints often falling between $5,000 and $20,000, and potentially more for very complex designs. Several factors influence the total price, including the project's size, the number of rooms, the type of drawings required, and the architect's experience level. You may also need to pay a structural engineer to ensure building safety, particularly for custom homes.

Whether you’re building a new home or building an extension on your existing property, you will likely need both a structural engineer and an architect. A structural engineer will determine what loads your foundation and framing can safely handle, and an architect will draw plans according to those structural calculations to simplify the building process. You can start by contacting a structural engineer near you, as many work alongside architects and can get all of the prep work done at once.
