Since 1985, I have been practising house design as a profession. In addition to this, I have been engaged in land subdivision and sales, as well as developing houses on those lands and selling them. Over the years, I studied Harmaness Appuhamy's book "Residential Architecture and Vaastu Science" and applied the knowledge gained from it to my projects in a practical manner.
As these efforts proved successful, I established an office at the Maharagama Minister's Building to share this knowledge more practically with others. With growing exposure through the media, I also began teaching and guiding students who wished to learn. As my work became increasingly recognised, I naturally expanded my focus into the field of commercial Vaastu as well.
During this period, I published books and magazines in order to share my knowledge more widely. Programmes such as Lakhanda "Home Clinic", "Nuga Sewana" and "Sandae Nimnaya" on National Television, Sri Lanka Broadcasting Corporation's "Nenasara", and "Niwahana" on Siyatha TV provided valuable platforms for sharing my expertise with the public.
While carrying out my professional work, I conducted several research studies to resolve various Vaastu-related issues that arose in practice. Because I successfully applied the conclusions of these studies to my work, my projects progressed more rapidly and became firmly established in real-world outcomes.
Background:
During house inspections, I observed that certain houses performed well even without a perfect match to the door chart. I wanted to understand what made this possible.
Sample / Data:
Approximately 300 houses were examined.
For a courtyard to be treated as an "entrance element," it must be capable of providing:

Background:
There is a widespread belief that the number or size of doors and windows has a fixed "truth" or strict rule. Earlier, I also believed this because I followed traditional opinions. Later surveys clarified the real situation.
Sample / Data:
Approximately 1,000 houses were studied.
which led some people to popularize unsupported "rules."
This belief is especially strong in parts of the southern region, where it is widely accepted with great confidence.
The meaningful factor is the door chart and correct spatial analysis, not superstition about the number of doors and windows.
Background:
The location of a well is widely believed to directly influence the household. I investigated what is truly valid and under what conditions it matters.
Key Observations:
Sample / Data:
Approximately 500 houses were used for the critical observations related to defects.
A well behind the house is not a defect in most cases.
Although a well in the front-right / Southwest area is often considered unsuitable, observations showed that if the well is located about 15 feet away from the house, it does not necessarily produce negative effects.
The most important practical rule observed was based on visibility: If the well is visible from the main door within the front 180° field of view (90° to the left and 90° to the right), then a well in the Southeast/South/Southwest zone may be considered unsuitable.

Background:
A common belief states that toilets should not be located in the Southwest direction. I tested this through direct observations.
Sample / Data:
Around 50 houses were directly observed.
The general belief that "toilets in the Southwest are always unsuitable" is incorrect.
A toilet can be placed in almost any direction except the Northeast (which is widely treated as sensitive in Vaastu interpretations).
I also observed a cultural factor: among many Tamil Hindu households, the North direction may be avoided for toilets due to religious beliefs about a deity associated with that direction. In such cases, they should follow their own belief system.
For people of other religions, that specific belief has no necessary influence, and planning decisions can be made without it.

These four research observations suggest that several popular beliefs in house planning should be re-examined through field evidence.
Concepts such as the courtyard, and the importance of airflow, daylight, and visibility, often provide more practical explanations than rigid numerical rules or generalized directional fears.
The research demonstrates that evidence-based practice, grounded in direct observation of hundreds of homes, offers more reliable guidance than traditional superstitions.

Thank you for engaging with these insights. We are continuously gathering new data and refining our understanding of architectural principles. Stay tuned for future observation reports where we will delve into more evidence-based findings to inform better design and planning.
