Classical Pavers serves both New Jersey and New York in the Tri-state area. We are masonry contractor company that specializes in the installation of outdoor living areas including paver driveways, walkways, patios, steps, stoops, retaining walls, culture stone, and fire pits. We are fully insured.

"Classical Pavers did a beautiful job replacing my front walkway! It was not a straightforward project because it was built on a steep slope with a curve. The owner Thiago, who oversees the project, was a pleasure to work with -- never used any pressure tactics, was very responsive to any questions, and gave a fair price. The two craftsmen who did the work were amazing! They arrived promptly every day, worked extremely hard, and did absolutely beautiful work. They hauled away all the old materials and tidied everything up when the job was done. We definitely would hire them again for a future project and highly recommend them."

I strive to design the clients vision aswell as provide renovation services of a luxurious kitchen and bath of their dreams. I pay attention to details and I work well with my clients to build their project scope of work. My focus is quality and professionalism!

"I was looking for a pro who was experienced, honest and could communicate to get the job done right. Dave was the man. He knew what I wanted and suggested options to give the project(complete kitchen and bath remodel) a 5 star review. After my rental was completely destroyed from a tenant, I was up a creek without a paddle. Dave and Pablo went above and beyond to create the Reno I was looking for. From the first interview to the end result, I have no reservations for recommending ModernKnight for any project. They were on time , completely transparent and accommodating every step of the way. Are you looking for the pro to get your job done? Look no further, Dave is the guy! Thanks again Dave and Pablo for everything and more! Freddy."

Guest house building services FAQs

In most states, yes—you can build a guest house, but every city or county sets its own zoning rules and building codes. Before breaking ground, check local ordinances, confirm lot setbacks, and secure the right permits. A local contractor or design-build firm can walk you through the paperwork and site requirements so your project starts on solid legal footing.

Yes—homeowners often tap a few different financing tools. A home-equity line of credit (HELOC) lets you borrow against your equity as you need funds. If you prefer a lump sum tied directly to the project, a short-term construction loan can roll into a second mortgage once the build is complete. Cash-out refinancing is another option: you replace your current mortgage with a larger one and use the difference to cover construction costs.

When you build a guest house, you’re creating a separate structure for hosting visitors without the full amenities needed for permanent living. An accessory dwelling unit, however, includes a complete kitchen and bathroom, meeting building codes for a long-term residence. This key difference makes an ADU ideal for long-term occupancy or rental income, adding enduring value to your property.

How many rooms you need depends on how you plan to use the space. Aim for one bedroom per every one or two occupants to make sure everyone has enough privacy and comfort. Added living and dining areas give you extra functionality, especially for rental use or long-term stays.

Most homeowners pick somewhere between 600 and 1,500 square feet to fit all the essentials. Make sure your design supports one to two occupants per bedroom and includes enough common areas for comfortable daily living. A well-proportioned layout boosts both functionality and property value.

No—a guest house isn’t just a bump-out on your main home. A bump-out is a small extension within an existing room for extra seating or storage. In contrast, you build a guest house as a standalone building with its own foundation and amenities, giving you a fully separate living area that can boost your property’s versatility and value.
