Web Analytics Made Easy -

About me – portfolio

I am Teoalida and I love doing research, collecting information, writing articles and making databases about real estate, cars, and other fields, as well as designing own housing models. Also playing games with buildings.

I made this website since 2009 to showcase my works, share knowledge and educational material, promote my services, and make new (business) friends.

All the articles, drawings, 3D models, Word and Excel databases, are my personal work. Except the photographs from Housing around the World section, which are linked to their original source, and the HDB brochures.

I also have few partners in programming, architecture and real estate agents, to cover additional fields and serve more customers when I am too busy. If you want to be partner with me you are welcome.

If you have any enquiry about AutoCAD, architecture, real estate, databases, research, data mining and analysis, or any other stuff covered by articles of this website, comments about my works, errors to report, suggestions, critics, etc, feel free to contact me via Live chat or email image

Housing around the World, research and educational articles

WorldI love exploring the world to study architecture, housing and living conditions, and write articles. While articles themselves do not produce money, they help home seekers, students, researchers and some businesses, increase website audience and occasionally people offer to pay me to do other works.

Currently I have 12 pages with general information for various countries/regions: North America, Latin America, Europe, North Korea, South Korea, Japan, China, Hong Kong, Singapore, Malaysia, Vietnam, Philippines, India, Africa, plus over 20 pages with detailed information about Housing in Singapore and 7 pages about Housing in Hong Kong.

AutoCAD design

Graphic DesignMy dad is using AutoCAD since 1995, I learned AutoCAD myself while watching him working and made my first drawing in 1998, over years I made numerous drawings from personal interest (hobby) as well as working for my parents or for customers who contacted me via this website.





Housing design – the Virtual City

Apartment DesignThe interest for architecture dates back from childhood but in 2008 I started studying it seriously, making “Teoalida’s Virtual City” with dozens apartments and house floor plans and 3D models designed in AutoCAD, some been inspired from various housing around the world, some being my original concepts.

Apartments ranging from 30 sqm 2-room studio to 200 sqm 6-room, based on an average 25-35 square meters per capita and 100 sqm average apartment size.



House DesignStarting from 2010, I completed the Virtual City with landed houses too, detached, semi-detached, terraced and cluster houses (landed condominiums), ranging from 50 sqm 2-bedroom to over 400 sqm and 7 bedrooms.

My experience was originally limited to making highly efficient floor plans and 3D models, but later I learned to make “construction drawings” by laws, fully-dimensioned floor plans, elevations, sections, as required for building permit.

Although designed primarily for artistic purpose, they are fully livable homes and can be built (virtual city = because I am not a developer, I don’t have capital to build them).

Housing design – architectural services

House DesignThe “Virtual City” 3D artistic hobby, have impressed people dreaming to build a house but also architects, turning into business since 2012. Many people advised me to pursue a career in architecture, but contrary of what most people think, I never been able to earn enough from architecture. Lots of bad customers from third-world countries ask me to do floor plans for free, do not want to pay an architect, and the few paying customers usually waste too much time for the little money they pay.

Furthermore, database services turned to be more profitable, so I have no reason to continue my career in architecture, I decided in 2015 to NOT do any more projects, unless there is a special case.

If you are building a house or apartment block and need drawings I can link you with licensed architects from various countries. DO NOT ask for house plans if you cannot PAY for service!

Palace design in AutoCAD

Palace DesignProbably the most beautiful piece of art that I ever made in AutoCAD, this 3D model is a virtual reconstruction of a REAL, abandoned building, which today was left in ruins.

Originally designed voluntarily in 2006, I improved it in 2009 and 2014 to show you my abilities of 3D modeling in AutoCAD and geometry design.

There are several architecture software (ArchiCAD, Blender, Revit) that can do better job than AutoCAD, but the little money earned do not justify buying more licenses.


Furniture & interior design in AutoCAD

Interior DesignIf I design buildings why I would not design 3D models of furniture and interior design too?

I do not have experience in interior design as high like the experience in architecture design.





Word books & Excel databases – data entry and web scraping services

World Cities Database

I am using Word since 1997 and my dad encouraged me write book-like things, but I learned also Excel myself and since 2003 I am using it more than Word, and today working in Excel represent my primary source of income.

For many years, manual data entry in Excel (sourcing from books, as seen in this video, or manual copy-pasting from websites), was my only way of creating databases. A slow process which limited the size of the databases I could make. Even in this slow process I made about 40 databases about cars, geography, real estate, gaming, etc, from pure hobby.

Starting from 2015 I learned web scraping, meaning programming a software to visit a list of given pages, copy specific data and put it into a CSV spreadsheet automatically, allowing me to quickly create new databases and sell via my website.

– The Geography works, country area and population, list of cities, etc, made in 1998-2005 writing data manually from Microsoft Encarta Encyclopedia, abandoned after connecting to internet in 2005 and discovering Wikipedia. Improved and published on website for first time in 2015.

– The Music Database with song ratings according my personal preferences, one of the most USELESS things that I ever made, started in 2005 and as 2016 still expanding it.

– The Skyscrapers Database, made in 2015, one of my first databases where I used a program to automatically scrap data from a website.

– The Mobile Phone Database, made in 2016 via web scraping.

What will be the next database to do?

Real estate database – data mining and analysis

HDB Database

One of my biggest research and data mining projects is the Singapore HDB Database, a table of 14000+ buildings with block number, street address, postal code, year build, number of units breakdown by flat type, upgrading programmes, etc. An original compilation of data centralized from multiple sources plus own research.

Started in 2009 from personal interest and put ON HOLD because the potential of turning into a business was under question, after discovering potential of Car Database, I resumed working at HDB Database in 2014 and finalized in 2015, after hundreds hours of work, it has been purchased by several real estate companies, home insurance, telecommunication, door to door services, etc.

In addition of HDB original research, I am offering Condo Database made via web scraping, and HDB Resale Flat Prices Database that include over 60 charts made in Excel.

Another project is the Hong Kong Housing Database, table with 1000+ public and private housing estates, made in 2011 for an insurance company (my first large project done at customer request and not as personal interest/hobby).

Car database – research and data analysis

Car DatabaseDue to my passion for automobiles and obsession for doing research, tables and statistics, I started in 2003 a car encyclopedia, several lists in .DOC format and tables in .XLS format which allows you to sort and filter car models. This include a table with 20000+ car models, detailed with 50+ columns of technical data, which required over 1000 hours of work!

The hobby turned into a business since 2012, but only after extensive transformation to make my hobby-made databases suitable for the unexpected audience. Since 2015 I created additional car databases via web scraping.

Every year, over 100 companies, primarily from Europe and America, looking for a complete, accurate and frequently updated vehicle database, are buying my Excel tables.

Car design in AutoCAD

Car DesignOne of my older passions was for automobiles, since 2000 I designed side views of few real cars in Paint, also my own car models, in Paint and later in 3D in AutoCAD.

“Teoalida’s Cars” are not very modern or sport cars, but they are designed with as many details is possible, and rendered with all photo-realistic effects available in AutoCAD, to showcase my skills of 3D modeling.

I no longer design cars. Last car I designed was in 2007 (photo).



Mapping design

Map DesignAs related with architecture and urban explorer passion, I love to design maps too!

Between 2004 and 2007 I voluntarily designed artistic maps for Ploiesti and nearby towns, vectorial drawings in AutoCAD then colored in Paint, but this turned in a high-effort job with no much usage and generating too little income.

In 2009-2010 I also made a very basic map of Singapore in AutoCAD which I published on website in 2016 and we will see if there is sufficient demand from people to worth completing it with more details.

Gaming – The Sims housing

The Sims 2 planned citiesMany architecture students who love games, do play The Sims game. Me too, I play The Sims series since 2003 and The Sims 2 became my favorite game, in which I practiced urban planning talent by building large neighborhoods with non-functional apartment blocks in 2006-2008, before moving to architecture in AutoCAD. I also built over 50 functional houses which I offer for free download on my website.


Web design

I am not saying that I am a web expert, but I made my website myself without any professional help!

I have high SEO knowledge that helped my website to be on 1st page of Google for dozens of keywords and raising traffic from 100 visitors per day in early 2012 to 800 visitors per day in 2014.

I do not know PHP yet so I cannot make complex websites on custom-made platforms. In terms of coding and programming, my knowledge is limited to HTML, CSS and WordPress platform. 90% people do not even know these basic stuff, so feel free to contact me for any help related to website building, promotion, optimization, etc.

Over years I made several friends in webdesign which I can give your projects to, for higher quality results.

Notes & frequently asked questions

I get often dumb questions like this:
What do you do for a living?
Why did you made these projects?
What is your profession / primary job?
How do you earn money? I do not see any ads! (really dumb question)
Why did you created this website? (question often from Singaporeans surprised by amount of housing information offered without being myself an agent)

Short answer: I created website in 2009 as portfolio of my works, primarily building designs made after a deep research on Singapore housing, and post in freelancing websites hoping to get customers in AutoCAD, but I did not won any project so I aborted. Few months later I decided to publish the housing research too to increase audience and serve Singaporeans with free information.

Early works were made from personal interest (voluntary, hobby) rather than for a specific customer. Once I found live chat software in 2012, website visitors started to contact me and helped me to understand market demands, or hired me for various projects. In 2012 I had first paying customer for CAD design and first sale of a database.

I abandoned most of non-paid hobbies to focus on working for customers, but AutoCAD / architecture was a horrible experience because I has been contacted by many individuals from third world countries and just few actually paid the price I asked (some insulted me for charging money, example 2014-04-02 and 2015-08-31). By 2015 I exceeded $1000/month, of which 80-90% came from sale of databases, website traffic and number of customers became higher than what I could handle myself so I started rejecting private projects to focus on projects that can be published on website and sold to multiple people.

I am NOT a company and I do not employ full-time staff. If you are architect, interior designer, programmer (experienced in data mining), or real estate agent, I can send you occasional customers. The number of customers that require services (other than buying ready-made products) and able to pay, is not high enough to hire full-time dedicated staff.

I never had a full-time job. I fill my time by working for customers paying me to do various projects, or do projects from personal interest and post on website for public sale, I still do voluntary projects for my pleasure / hobby, but only if I can help large number of people with free information. If you want me to do a project privately just for YOU, you should PAY me!

For private projects I charge a hourly price of 1/100 of past month earnings. If you are looking for long-term outsourcing, I am no longer a cheap employee as I was few years ago, BUT I can connect you with my partners from Asia who are happy with $10/hour. See Canada architecture company who wanted to employ me (full time?) which would have been unprofitable for me but my partners were VERY interested.

As 2018, per month the website have ~40,000 visitors, ~500 contacting me via chat or email, ~50 buying something or paying a service, while the rest are thankful for free information offered on website.

Posting ads on such website selling products or services is stupid. Ads are good for non-profit websites with large traffic. With 40,000 visitors per month estimated earnings from Google AdSense would be $200. But 99% people find ads disturbing, customers may see ads of competitor services, and I will lose sales worth more $ than what I earn from ads.

What is all this mix of stuff on same website?
Are you CAD designer, researcher, database provider, gamer, or…?

I am ALL OF THEM! This is PERSONAL website and my life is very diverse!

Several people suggested making separate websites, one for Singapore housing, one for CAD services, one for database services, etc. This will reduce traffic on websites promoting services. Having all them on same website is an advantage, Singapore pages getting lots of traffic plus Facebook likes and tweets helped services pages to appear higher in Google, also some drawings and databases are related to Singapore housing. Then, I got several collaboration offers from foreign companies who did not visited /design or/database sections directly, they found my website while looking for info about Housing in Singapore or Housing around the World then clicked About me page, saw that I am also in architectural design and data research and contacted me for paid work.

Where is your office located? Can I book an appointment?

I work from home ONLINE to people from all over the world, as typical freelancers do. I do not have any office and I usually do not meet customers. Even if you live just few kilometers away from me, I prefer to not meet in real life unless is absolutely necessary. If you need to employ someone to work at your office, or travel somewhere, I am NOT the right person for you.

Do you get paid to chat with people? Do you help people for free?

I am NOT employed, affiliated with any government or company, or get paid “to help people”. I am independent, this is my personal website and only YOU can pay if the consultation or services offered helped you!

This is valid especially for Singaporeans, if consultation with me made you to decide to buy a $500,000 property, I appreciate if you can donate me few dollars.

While chat consultation is FREE, research, drawings and database services are NOT FREE. This is how I make a living. If you are NOT PAYING for any service you are advised to not waste too much time chatting (as these kids did).

Take example from this Indian who PAID me $20 for architectural consultation.

    First time user – purchase seamless and easy.

    1. Better post a longer comment to explain what did you purchased (Australia car database), take example from Damir comment https://www.teoalida.com/cardatabase/about/comment-page-1/#comment-506
