10 Min Read

The city of Denver is the capital of Colorado state and is home to more than just the ski resorts of the Rocky Mountains. The city is a metropolis that dates back to the Old West period. It houses iconic architectural masterpieces such as the Larimer Square. It is named after the pioneer General William Larimer, and it features historical landmarks from the 19th-century. The city square is the first district ever established in the city and composed of its first commercial block, Denver’s first residences, and its first city hall.

You can also find the Denver Art Museum that is known for its display of native artworks, with a comprehensive collection of over seventy thousand distinguished works encompassing world history. The ultra-sleek and post-modern museum was designed by renowned Italian architect Gio Ponti in collaboration with James Sudler Associates, a local firm in Denver. It is located in the Civic Center and is the most extensive art museum between the Pacific Coast and the Northeast of Illinois.

Denver is also home to the sprawling mansion-turned-museum of Molly Brown. Margaret “Molly” Brown is a woman who came into prominence after surviving the Titanic tragedy in 1911. After Molly’s harrowing experience, she dedicated all her resources and focused on activism and philanthropy. During Denver’s city-wide renovation of the sixties, a group of history preservationists known as the Historic Denver, Inc. fought to conserve Molly’s mansion by turning it into a historical museum. The organization began restoration efforts to preserve its original English Baroque style while carrying out necessary renovations to accommodate new exhibits and visitors.

The city is home to highly-qualified remodelers and accredited renovators. These professionals carry out the necessary developments to preserve or enhance the city’s infrastructures, which proves beneficial to Denver’s homeowners. In 2018, the city’s housing inventory was at its lowest since 1986. With today’s economic climate causing fluctuations in the market, a homeowner’s best bet for more liveable space or change in environment is to go with home additions or remodeling. Below we’ve listed seven of Denver’s best contractors who specialize in home additions.

The company offers clients all across Denver full-service Design-Build packages. Classic Homeworks strives toward achieving the delicate balance of innovating and preserving the city’s renowned architecture. The firm maintains architecture rooted in Denver’s history while integrating modern functionality.

Classic Homeworks was established in 1985 and was bought by Kelli Cost when she focused on residential instead of commercial architecture in 2005. Kelli comes from a successful background in commercial architecture and switched sectors when her passion for helping others in construction proved more valuable in building homes for families than towers for large corporations. She acted as the firm’s senior project developer and general manager, instilling ethics of integrity and professionalism within the firm’s team. Today, she acts solely as the general manager supervising team members to carry out the same level of ethics Kelli used to fortify the firm.

As one of the only female owners in a male-dominant industry, Kelli remains steadfast in breaking down stereotypes for women. She has successfully earned accreditations from the industry’s leading organizations, such as the National Association of the Remodeling Industry and the National Association of Home Builders. The firm is also certified by the EPA in Lead Safety. Its EPA certification qualifies the firm to manage structures that predate 1976, before the ban on lead-based materials was implemented.
