Technology is being widely adopted in Construction and Real Estate sector these days. Pandemic has made technology exigent in every walk of life and Real Estate sector is no exception to this paradigm. However, it must also be noted that technology is becoming a ubiquitous savior and an important tool for sustainability of enterprises. Real Estate has been a barometer for measuring progress of economy and its central theme of debate. If economy has to improve, much depends on revival of Real Estate Sector in general and retail purchase such as residential apartments in specific. Retails purchases have literally come to a halt due to various reasons such as frequent lock downs, non-movements, lack of confidence and absence of trust in future commitments. In this context, sustainability of this sector has been made possible by adoption of cutting edge technologies. In this paper the technologies are reviewed and how each brand is able to use technologies to better their marketing and sales efforts. The paper will also be able to convincingly illustrate technologies that could be used by companies that are smaller and medium scale in size, so that sustainability does not restrict itself to Tier I cities, but also revisits Tier II cities which are emerging markets.
