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 am an architect working from my home office in Beverly Glen. I have worked on custom residence and additions ranging from modern houses or very old traditional homes with a lot of character. I work on both small and large projects with the same enthusiasm. Architecture and space design equate to quality of life. I attempt to allow my clients to be part of the design process and participate in the design decisions from beginning to end while removing the stress from the construction process. I am one member in a time of three that includes the owner, the architect, and the contractor.

"He's super hard-working. Really knows how to get building plans approved. Very experienced & very affordable."

Custom Home Builders questions, answered by experts

While some highly experienced homeowners can frame a house independently, it is not advisable. You will need ample carpentry experience, a team of helpers, and professionals to sign off on your work to meet local building codes. For the safest outcome, we recommend buying or building a house with the guidance of professionals.

Framing is often the most expensive phase of building a house because it’s time-consuming and requires a lot of materials. It costs between $20,000 and $50,000 on average, depending on materials and labor costs. Before construction begins, it’s possible that purchasing land is the priciest step in the process. Some plots of land sell for $3,000, while others cost upwards of $150,000.

Whether it’s more affordable to gut a house than build a new one depends on the markets where you'd be buying and selling. However, it’s usually less expensive to renovate a home than to build new construction. 

Most homeowners pay between $100,000 and $200,000 for demolition and remodeling costs, whereas the average cost to build a new home is between $139,000 and $531,300.

Building a new home can be more expensive than buying an existing one, depending on the housing market in your area. Many homeowners still find that building a new house is worth the investment as they can choose the exact layout they want, as well as to choose their own floors, wall coverings, appliances, and finishes. If you live close enough to the build site, you can also stop by to check on the builder’s progress, which can provide some peace of mind that the project is worth it.

The cost of a home renovation depends on its complexity and extent. A large remodeling project may top $71,000, while a smaller project may cost around $15,000. Using a home renovation cost estimator before you begin can give you an idea of what you can expect to pay to revamp your home.
