"We added a great room, entryway, deck and second floor room to a ranch. Kip has a great design sensibility and we worked together without an architect to come up with a plan. We've been extraordinarily happy with the result; we love the house. The older section works seamlessly with the newer section. Kip pays attention to details. After the work was done, Modern Habitat has been responsive to whatever issues that arose. We are truly appreciative!"

iCornerstone offers design through construction services and promotes Consumer Controlled Construction as a solution to over-pricing, under performance, unrealistic allowances, and quality issues. We provide designs, labor and material specifications, accurate project costs, camera monitoring, invoice review, project accounting, and construction support that allow the homeowner to act as the general contractor easily and with a minimal time commitment. The first three carry an hourly rate of $100, while the fourth is 15% of the cost of the work as you have defined it. After a free Initial Consultation, we provide a proposal for the cost of our services. Our platform networks regulators, engineers, subcontractors, service providers, and suppliers involved in your project so that everyone knows what everyone else knows, which is the hallmark of transparency and accountability. Everyone is on the same page. Their E-folios resolve the dilemma of "If only I had known, I would have asked." Everyone benefits, and nothing like the platform exists in the industry. Clients must provide us the names of subcontractors we do not know as a means of proving to themselves we do not steer business or have a conflict of interest. This strategy helps our network grow and ensures fairness. Our free, online, Consumer E-Folio / Project Organizer / Property Profile / Research Tool will help you, even if you do not involve us in your project, comes with no strings attached, and respects your privacy. Simply register at icornerstoneinc.com and have fun using it. We claim three remarkable achievements: no client has ever gone over budget; no subcontractor has ever been overpaid or unpaid without cause; and all clients receive the highest quality at the lowest price.

"For our home addition/renovation we are very grateful to have found Richard Connolly and his site iCornerstone. Our vision was a Two-story + basement + livable attic space home addition which would provide significant practical square footage to our existing house and integrate seamlessly with it. We interviewed a number of general contractors but we were overall a bit uncomfortable after the interviews due to gaps in transparency regarding how costs were calculated and how timelines were established, resulting in some lack of confidence. We happened upon Richard’s iCornerstone site via Angies. Richard provided an extremely transparent and detailed description of his unique and practical process, which delivered a set of superb designs along with a truly logical, transparent, and honest listing of costs, both materials and labor, at all stages, and how those costs were derived. Richard also delivered transparency on timelines, and he provided recommendations for all the needed tradespeople that he had historically a close working relationship with; alternatively we could have selected tradespeople of our own choosing. Richard and his process gave us the utmost confidence for proceeding. We proceeded with our renovation under Richard’s guidance and his own crew and the entire process went according to plan with excellent communication, rapport, and confidence at all stages from excavation to final finish work. Transparency, confidence-building, dependability, highly knowledgeable, customer-friendly, and results-oriented are all terms we would use to describe Richard and the iCornerstone process. We strongly recommend Richard for anyone contemplating any home renovation or home addition, large or small."

FAQs for addition to existing structure building service projects in Leominster, MA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
