"Dee is fantastic! We loved the design Mike came up with for our backyard makeover. Then once construction started we realized we had made choices that needed to be changed. In every case Dee's suggestions (stucco the walls instead of paint, don't use DG next to the pool, run wood fence topper horizontally) turned out to the best. We are so glad we listened to him. Our finished backyard looks like an art installation but one where you can feel comfortable and at home. Now a year later we had them come back for a few tweaks and again Dee's suggestions were the right ones. We are happy we choose G & L and plan to use them again next year when we tackle our front yard."

"Stuff happens, and this business knows how to handle it! We had a stain on the ceiling. Ofri from BTB came over and turned on the water from the upstairs bathtub and then the shower stall. The ceiling became moist after the shower was turned on. Ofri then came back with a plumber. He turned on the upstairs bathtub. After they left, water dripped from the ceiling. Ofri had the plumber immediately send over a team for a service call. They broke open a hole in the ceiling and found that a pipe leading to the bathtub was so rusty it had holes. They took videos showing other pipes leading to the bathtub were also very rusty. While the team was still there, Ofri gave us prices, sent over the paperwork and the pipes were replaced within a of couple hours. Fabulous! Ofri had thought it would take a lot longer to complete the plumbing work. Therefore, her pricing did not align with the actual work performed. She brought in Alon, who substantially reduced the price to our satisfaction. Their responsiveness and reasonableness earned them my highest rating. Thank you Ofri, Alon and the BTB team!"

Second story addition building services FAQs
For many homeowners, building up is worth the expense because it provides the extra bedrooms or living areas that can’t be accommodated within the existing footprint. A larger, updated home often commands a higher resale price, recouping a sizable share of the project cost while allowing you to stay in the neighborhood you love. Run the numbers with a real estate agent and contractor to ensure the expected return and day-to-day benefits align with your goals.
Whether it makes more sense to build up or out depends on your lot, budget, and local code. Building up preserves yard space and involves less foundation work, but you may need to vacate the home during construction. Building out avoids staircases and can proceed while you stay put; however, it encroaches on the yard and may face setback limits. Compare both options with your contractor before making a decision.
A structural engineer will first inspect the existing foundation for cracks, footings, and load capacity. Depending on the findings, the crew may pour new concrete footings, install steel or concrete piers, add reinforced beams, or tie additional rebar into the slab. These upgrades redistribute the weight of the new floor and bring the structure up to code. Your contractor will outline the specific reinforcement plan and timeline once the engineering report is complete.
