Mo has the ability to envision a room and assist clients in creating a designer look. Upon entering a Castleton home, one of the first things that may catch your eye is the staircase. The hallways are graced with magnificent stairways, monumental railings, art niches and crown moulding. Mo typically works with a combination of high quality materials that include plaster, hardwood, granite, and stucco that offer a luxurious appeal throughout his clients' homes.

Unique ceiling details are another element in a Castleton home, which exemplifies their attention to detail. These details range from elevated and curved ceilings to hidden lighting nested behind neoclassical plaster moulding surrounding a mural in a barreled ceiling. To complement the architectural design, Castleton has the lighting creatively planned for each room in the house according to their clients' desires.

Outside, exterior mouldings accent brick, stone, or stucco, which accentuate a fully landscaped yard. Castleton creates a contemporary or traditional look, depending on the clients' preference.

However, Mo's personal pride comes from knowing that the quality and workmanship of the granite and hardwood floors, equals the quality behind the drywall and under the concrete. He uses extra thick plywood to build solid roofs, water pipes are insulted for sound proofing, and seven days are set aside for the foundation to cure properly. All of these measures and much more are taken for the security and comfort of the home buyer.

Even though as Mo says, "I'm the only one who sees it, and probably the only one who notices it", it gives him peace of mind knowing that his clients are not going to run into trouble down the road. He considers himself the home buyer's eyes and ears during the building process, and makes himself available to them 24 hours a day before and after the transaction. He firmly believes the job has to be done right the first time, and he expects the same exceptional quality from his tradespeople, "regardless of the size of the project", he says, "quality is first priority."

Most of Mo's clientele have been referred to him from previously satisfied customers. Maybe its because home buyers appreciate the quality of the homes he builds. Mo Shahlavi and Castleton Custom design and Build Ltd. have an envious reputation in the market due to their fine approach to construction and client satisfaction.
