Residential & Commercial Design. Welcome to Clarke s Design Service. Drake & Dale Clarke are second generation building designers who have a combined work experience of over 35 years. Clarke s has designed over 8,000 homes in St. Tammany Parish and its surrounding areas. Building a new home or renovating an existing home,can sometimes seem to be an overwhelming task. Our goal is to provide you with a general knowledge of the construction process and a detailed,well thought out design,that meets your goals and budget. We design all of our plans with Softplan,a state of the art computer software that allows us to provide true perspective,3D drawings,inside and out. You will be able to see what your home will really look like,before construction begins. This can be very helpful for those who have a hard time visualizing two dimensional drawings. We also take into great consideration the efficiency of a design: using even material lengths,footprint to lot size,sun direction,etc.
