Abstract This paper aims to compare and contrast the Architecture and the concept followed by Architects from the 19 th Century and 21 st century and how their ideas varied through time. A detailed analysis is done by comparing the Red House, Kent, United Kingdom constructed in 1859-60 and the iT House, California, the U.S.A which was constructed in 2007. An Analysis over the years Architectural aspects and Concepts of Architects have been reviving over the centuries giving way to many Architectural Revolutions. The major influence of Architectural Concepts and the construction methods have influenced the Residences and the lifestyle of the people. Some of the major examples of the earlier residences are being conserved today in many countries which stand as the monument for the earlier Architectural revivals. The major architectural features could be seen on the residences of United Kingdom which marks the Victorian, Georgian and Tudor architecture. Red House in Bexleyheath, Kent, United Kingdom is an explicit example of this architectural reformation that took place during that time. The house was designed by Philip Webb in 1859 and was the work was completed in 1860. The House withstood from others due to its predominantly red walls made of brick and red roof made of clay tiles. Major features of Gothic Architecture were adopted in this design with pointed arches and sash windows.

Red House is still seen today as an unequivocal range of material , workmanship and design. (Lethanby, W.R, 1935) A noteworthy example during the modern era is the iT House constructed on the minimalism concept. Built-in 2007 by Taalman and Koch Architects, this house was constructed of prefabricated materials taking just weeks to finish construction. The house is harbored at Yucca Valley, California where the house parts were constructed off-site and assembled on-site to form the house. The interiors also follow a minimalist design aspect where the comfort of the occupants is taken into prime consideration as well the relationship with the surroundings and residence. (Taalman Koch Architecture,2009). Minimalism, as the word signifies was considered a major breakthrough in the architectural world, and the design concept is kept at expressive yet simplified lines. This approach gives more value to empty spaces and cleanliness. Minimalist Architecture began its form in 1950 forming new styles in Architecture, Lifestyle and concepts. This further developed to its perfect symbolism in the modern era in the increasing commercial and consumer styles. The major motto of minimalist Architecture is ‘Less is more and increasingly followed in the entire major parts of residential archi
