I provide residential structural engineering services to both homeowners and home improvement contractors. These services include plan preparation, design of structural members, structural evaluations of existing buildings, review of plans prepared by others, design of sanitary systems and on site drainage systems if necessary. All work is done by me, a registered professional engineer in New York, and I also conduct inspections and evaluations.

"Was Awful. Measurment's were off. Plans were incomplete. After he measured the rooms, we had to remeasure the rooms ourselves and send them to him. I then had to go to his house to pick up the plans. I submitted the plans at which time I was told that I needed to get then done again by a professional. Held up the construction by several weeks. Save your money. Do not use Lou."

High end architect specializing in making a house feel like home! I make people’s dream homes a reality. There is nothing more satisfying to me then improving the quality of life for my clients and giving them a house that they are able to make into their homes. I have been a licensed architect since 2015 and am currently registered in Rhode Island, Connecticut, New York, Maine and Massachusetts. With my NCARB certificate I am able, if necessary, to obtain reciprocal licensure throughout the country in a short time period. I am inspired by our local built environment, humble materials, classical building forms and traditional building details. I have a strong interest in the reinterpretation of classical building forms, blended with contemporary open floor plans. I have a stronger interest in helping to guide my clients to ways of improving the quality of their lives through adapting the built environment to meet their needs.

"He was pretty responsive, caring, look into our concerns, manage to work everything, willing to work on the plans."

Custom Home Builders questions, answered by experts

A contractor can install your shipping container home in as little as 90 days. This is notably quick compared to a traditional home build, which can take more than a year (providing there aren’t permitting or construction delays that make the wait even longer). For the quickest installation, choose a prefab container home.

The average cost to build a modular home is around $270,000, and most modular homes total between $180,000 and $360,000. Of course, this price varies significantly by location, and the price tends to follow the cost of living in the area. There are quite a few other factors at play that can affect your pricing, including the following:

  • Number of bedrooms and bathrooms

  • Site preparation, including land clearing and leveling

  • Type of foundation

  • Utility connections

  • Cost of building permits

A custom home is one that you design from the ground up, allowing you to customize everything from the square footage to the interior layout to all of the materials used. A spec home is one that a builder has designed and gotten approvals for. Spec homes may give you some limited options for the layout and materials, but most of the build is pre-set. Custom homes cost more and take longer to build.

If you want to make your home eco-friendly, enjoy low maintenance, and love the fact that its looks will take people’s breath away (and not because they were trying to blow your house down), then a modern brick home is right for you. You can hire a mason to get the building process started for your brick home.

But if you’re not fond of the color and don’t want to deal with the process of repointing or other repairs, consider going with vinyl or wood. These materials offer a lower cost. While they tend to require more maintenance, they don’t cost nearly the same as exterior brick house repair.

The longest part of building a custom home is the design phase. It takes multiple professionals and a ton of work to bring your vision for your dream home to life while sticking to a homebuilding budget and also ensuring everything is built to code. Expect the design phase for a custom home build to take six months to a year.
