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."

Custom Home Builders questions, answered by experts

One of the best ways to negotiate with a homebuilder is to forgo price reductions. Instead, negotiate over upgrades and incentives, as many builders are more willing to go down that road than to decrease their own fee. Even if they were willing to take a cut, a reputable homebuilder often knows their worth, so a willingness to negotiate could be a red flag. Beyond that, builders are typically willing to negotiate closing costs instead of offering a discount on the base price.

In most cases, you should get an architect before you hire a builder. An architect will be the one to draw up formal plans for your project, including guidelines and even material lists for your builder to follow during construction. Many architects can even help you find builders, choose one for your project, and negotiate prices. Some are also willing to act as project managers throughout the process, working closely with a builder from start to finish.

Start by researching local contractors with experience in cottage construction. Ask for references, check licensing and insurance, and review completed projects. Compare multiple bids, making sure each includes the same scope of work. A good contractor will communicate clearly, provide a detailed contract, and ensure all work meets code and safety standards.

The most significant expense when building a barndominium is constructing the metal shell, which includes the roof, doors, and windows. Additional exterior components impacting the overall cost include metal siding and the concrete foundation.

Historically, Tudor homes originally stemmed from the 15th and 16th centuries, while Victorians appeared during Queen Victoria's reign in the 19th century. The design and structural differences are significant as well. The many types of Victorian architecture—such as Italianate architecture—typically feature ornate trim, wood siding, wraparound porches, and tall towers on top, such as belvederes. On the other hand, Tudor-style homes feature white stucco exteriors with exposed wooden rafters marking the house frame both inside and out.
