Customers say: Super punctual

"Dave was a game changer for us. I had previously hired a different architect, who would miss deadlines and take multiple days to deliver the updates to the design. Now working with O'Brien Custom Home Designs it has been a 180-degree change. Dave delivers or beats his target delivery dates, provided a very sound plan for the home (he improved the previous architect's work) -- both exterior and interior look great for our lake home. I plant to hare O'Brien Custom Home Designs for my next project. I highly recommend."

Architects FAQs, answered by experts

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.

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

Drawing your own floor plans is acceptable for many kinds of projects, including interior design and room layout. You can use floor plan software to create the plans but keep in mind that the floor plan will only be as accurate as the measurements you take and enter into the software.

You have three options in terms of professionals who can draw up blueprints: a draftsperson, an architect, or a structural engineer. A draftsperson can sometimes draw up plans for new construction, but they more often work from approved plans for alterations or to provide 3D drawings. Architects are usually the best option for standard residential construction projects. Structural engineers might be necessary for custom home builds or for alterations that could affect your home’s structural integrity. Draftsmen cost the least of the three, followed by architects and then structural engineers.

Hiring a contractor with knowledge about historic renovations and reviewing their previous work is important. You can find a historic home renovation contractor by calling your local historic preservation office, historical society, or any local historic museums nearby. The staff may have suggestions for specialized contractors who have worked for them. You can also ask them about historic home restorations that you have seen and liked in your area to get recommendations for pros.
