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."

"Do not recommend. I hired Hedgemond Planning and Development to prepare ADU plans and submit them to the city for approval. Nearly two years later?and after paying over $10,000?I still do not have an approved ADU. Throughout the process, timelines were repeatedly missed and expectations were not met. The company overpromised and underdelivered. I chose them because their pricing was lower than other firms, but the delays, lack of results, and ongoing frustration ended up costing far more in the long run."

Architects questions, answered by experts

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

There are differences between universal design and ADA accommodations, but the outcomes are often similar. While universal design is a proactive process that takes a social justice approach to accessibility for all, ADA accommodations are focused specifically on accessibility for individuals living with disabilities. ADA accommodations often take the shape of wider doors and hallways, ramps, elevators, lower counters and sinks, and easy-to-grab door handles; universal design can include these plus emphasize better lighting, tractioned floors, and other building elements that allow all people to use buildings more comfortably.

With proper training and experience, reading blueprints is fairly straightforward and not very difficult. If you don’t have the necessary knowledge to interpret the symbols, abbreviations, and other notations used, blueprints may not make sense. Learning to read blueprints can help you understand the construction process and keep you more involved and informed when you’re building a house.

Yes, architects specialize in both new construction and renovation projects, ensuring that additions blend seamlessly with existing structures while meeting safety standards.

A blueprint is more detailed than a floor plan. There are different types of floor plans, one of which is a type of blueprint view. However, the blueprint will contain more information about that plan and is drawn to scale. Most residential floor plans give homeowners a simplified view of their construction project, while blueprints have all the details to turn that plan into reality.
