"Working with Ellen Marquardt was an outstanding experience from start to finish. She asked thoughtful questions to truly understand how we wanted to use the space, and her visuals—floorplans and 3D renderings—made decision-making easy and stress-free. Her deep knowledge and clear explanations of the “why” behind each design choice gave us total confidence in the process. Highly recommend!"

"Adam and his team are fantastic! Whenever I am in a bind and need them to come out right away they fit me into their schedule - even if it means being out in the rain! Their work is impeccable and I always get compliments on what they have accomplished. They take all debris away and are always at my home working in a very professional manner. Another great thing about The Grounds Guys is that they always try to keep their work as cost efficient for me as possible. I would absolutely recommend them to everyone!"

Architects FAQs, answered by experts

If your project is complex, it may make sense to hire an architect to draw plans. An architect might also be a good person to hire if you want to ensure your plans adhere to building codes and regulations.

Blueprints are generally available for houses built after the early 1900s. Before then, detailed building schematics like blueprints were rarely used and even more rarely saved. If you have an older house and need blueprints, you can have a new set drawn up by an architect or draftsperson.

Regular meetings, reviewing drafts, and providing input on materials help align the project with your vision.

Depending on what the blueprints are for, a qualified draftsperson, contractor, or architect can draw them up. In some cases, including specialty permitting for a build, you may be required to use a licensed architect. 

In many cases, a blueprint drawn up by a certified professional is required before a city or municipality approves a permit. 

Some homes, like those with flat roofs, may not have eaves at all. Some contemporary-style homes also lack eaves, although many may have abbreviated eaves to divert water and protect the walls and foundation. Homes without eaves often have specific types of gutters affixed directly to the edge of the roof to provide adequate drainage.
