RERA stands for Real Estate Regulatory Authority came into existence as per the Real Estate (Regulation and Development) Act, 2016 which aims to protect the home purchasers and also boosts the real estate investments. The bill of this Parliament of India Act was passed on 10 March 2016 by the Upper House (Rajya Sabha). The RERA Act was effective on and from 1 May 2016. At that time, out of 92 sections only 52 were notified. All the other provisions were effective on and from 1 May 2017.
RERA was established to enhance accountability and transparency with respect to housing transactions and real estate. Here are the salient features of this Act:
  • Establishment of Real Estate Regulatory Authority in every Indian state in order to monitor as well as adjudicate and arbitrate any disputes with respect to real estate projects in the concerned state.
  • Establishment of a fast-track mechanism for settlement of disputes. This will be done via an appellate tribunal and dedicated adjudicating officers.
  • All real estate projects must be registered with RERA so that the authority will have jurisdiction over the projects. The registration of a particular project can be rejected by the authority if guidelines have not been adhered to.
  • In case a promoter wishes to transfer or assign a majority of your rights and liabilities in a real estate project to a third party, written consent from two-thirds of the allottees will be needed in addition of the written approval of RERA.
  • If there is any default from the side of the buyer or promoter, both will be liable to pay an equal rate of interest.
  • If the promoter causes any losses to the buyer due to other people laying claim to property (defective title of land) which is under construction or has been constructed, the promoter will have to compensate the buyer. There is no limitation provided by any law currently with respect to the compensation amount.
  • If a person has any problems regarding violation of the provisions or rules of this Act by a promoter, buyer, or an agent, they can file a complaint with RERA.
  • While an enquiry is taking place, RERA can stop an agent, promoter, or buyer from continuing any activity against which a complaint has been raised.
  • If any of RERA’s decisions regarding a complaint is not satisfactory, the aggrieved party can submit an appeal before the Appellate Tribunal.
  • If the promoter fails to follow RERA’s orders, they will have to pay a penalty. This amount could be up to 5% of the evaluated cost of the property.
  • If the Appellate Tribunal’s orders are not complied with, a penalty will have to be paid. This can either be imprisonment for up to 3 years or a fine (up to 10% of the approximate cost of the project), or both.
  • If a company commits an offence under this ACT, any person who was in charge of the business at the time of the offence being committed and the company will be held guilty and will be punished.
  • No civil court will have any jurisdiction with respect to any matter that comes under RERA or the Appellate Tribunal’s jurisdiction. As such, no court can grant an injunction with regards to any action taken by RERA or the Tribunal.
Vastu is seen as an ancient science of architecture; it integrates architecture with nature. It provides guidelines to build a house or choose the one which makes the occupants' lives fulfilling, prosperous and joyful.
Vastu shastra is all about managing the energies in the space that you have to the best possible extent.
However, the truth is Vastu shastra does not specify a direction as being good or bad. Any house that’s planned in accordance with Vastu principles can play a part in bringing success and happiness to its residents due to the good flow of energy.

Scientifically, the East or North directions are preferred because it is easier to orient the house towards them compared to the South or West, which entails a bit of effort.

According to vastu experts the southwest corner of the house is best suited for the main bedroom. The guest bedroom or children's bedroom should be positioned in the northwest. Make sure that there are maximum windows on the east and north walls.
