Whether you're upgrading an existing structure or building from the ground up, Peter T. Erdelyi & Associates, Inc has the expertise to oversee your project through completion. We have designed more than 10,000 structures in the Los Angeles area over the past four decades; from apartment buildings to new single family homes to additions and remodels both for residential and commercial clients. Our team of professional engineers, drafters, expeditors and project staff will deliver plans that withstand the test of time.

"The work Erdelyi associates did is great, but communication and timeliness were lacking. I didn’t have a consistent point of contact throughout the project - it just seems my project was handed off from one person to the next with no continuity and I had to proactively reach out for updates."

"I really appreciate Arch. Leslie Anderson taking the time to analyze the work my internet provider was planning to do and for offering your insights—all without charging for the consult. It was very kind of you! Thankfully, a tech from the new provider came by today and confirmed that the wire can actually be installed internally, so no need to run it along the exterior walls or bury it in the stucco channel. I also understand now that nothing should be buried in the stucco channel. Thanks again for your time and expertise!"

Architects questions, answered by experts

Stone, marble, and brick are common building materials of Neoclassical architecture, though you will also find wood flooring and a range of natural stone tiles. Since several home styles fall under Neoclassical architects' umbrella, a range of building materials—including traditional wood framing—will make an appearance.

Check reviews, compare quotes, and verify licensing. Ensure the builder has experience with modular construction.

Many drafters go on to continue their education and become architects. Drafting is a necessary skill for architects, so learning drafting is often the first step on a path toward becoming a licensed architect. Drafting can also be a career on its own, with plenty of drafters choosing to specialize and focus solely on drafting.

On average, the cost to hire an architect is between $2,200 and $10,500. Hourly rates for professional architects range from $45 to $250 per hour, depending on the architect’s experience level and location.

The cost for architect services vary depending on several factors, including:

  • Location

  • Project type

  • Experience level of the architect

  • Local demand for the architect’s services

  • Overall cost of the project

Blueprints for standard home construction will usually range from $1,500 to $2,500 and average around $1,800. Your pricing will likely be higher if you’re building a custom home, as you’ll need to pay a structural engineer to weigh in on building safety. The size of your project, the number of rooms, and the type of drawings you need can also play a role in your total cost.
