"I recently hired Home Options for a variety of home repairs and I could not be more pleased with the results. From the initial consultation to the final walk-through, the entire experience was professional, efficient, and hassle-free. The team was efficient, keeping the worksite clean and organized throughout the project. They took the time to thoroughly explain the scope of the work, including the options available to me, and offered valuable suggestions that improved the final outcome. What really stood out was the quality of the work. The repairs were done to a high standard, and you can tell they take pride in their craftsmanship. Communication was excellent.

The Narrow Lane Company is a full service landscape company dedicated to creating and maintaining beautiful outdoor spaces you'll absolutely love! All work is done in a timely, professional manner and 100% guaranteed.

"Worst experience working with a contractor we have ever had. Lack of communication was astounding. Reached out to start the project on our tiny front lawn in June/July. Didn't start planting until mid October. Was told there were 5 jobs in front of ours. Ignored photos of exactly what we wanted. Finish product is passable at best. Would not recommend."

Addition to existing structure building services FAQs

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
