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

Yes, home builders need to be licensed in every state and municipality in the country. The specific license required varies based on the location and the work, but most states require that the builder hold a general contractor’s license at minimum. Some states and cities also require that plumbing, electrical, roofing, and sewage system construction require individual licenses, in which case the builder may subcontract the work. You can use Angi’s contractor licensing tool to confirm that the builder you’re considering holds all the proper licenses.

Whether a prefab home is worth it or not will depend on your personal needs and preferences. Overall, prefab homes tend to cost less than traditional homes, although they also tend to have lower resale values. Another thing to consider is that prefab homes usually last 50 to 60 years or longer, while traditional homes last 50 to 100 years or more.

Yes, you can finance cottage construction through several options. Construction loans provide funds in stages as work progresses, while home equity loans or lines of credit are available if you have existing property. Some lenders offer a combined construction and permanent mortgage. Always review loan terms and payment milestones before committing.

Yes, a home builder should have a builder’s license and insurance. States have different requirements for builder’s licensing and certifications. Be sure to check our state licensing tool to review your local home builder licensing guidelines.

As you browse our pro listings, take note of the “Angi Certified” badge. Angi Certified businesses meet our standards for certification, which include:

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Buying a house is easier than building one from scratch. Buying an existing home is almost always faster, even if you need to make renovations once you move in. When you hire the right team to build a home, they will simplify the design and build phases so that there is little guesswork throughout the process, but building new construction will almost always take longer than buying an existing home.
