Legal Building Plans and House Design

What would an architect and construction company be, without doing house designs and building plans.

You can check some designs here. If you have your own visions, tell us, how your house or villa shall look and we start immediately to design your house and make legal building plans for you. Our architects and engineers are registered and have an official certificate.

Depending on the house or project size, our building plans take around 2 weeks. 


The best comes for last: Our building plans are free if you decide to build your house with us. Building with us means you get high quality building materials between B+ to AAA+ grade. This depends on you and your budget.


We do not build C grade houses due to we give warranty to our clients. We want you to live in your house even after 15 years and it is still in a "new" condition. C grade houses can cause serious problems in safety and structure, the house may sink down which will end up in huge floor and wall crackings and worst case scenarios beams and columns will crack and the house can collapse.


Also all of our houses come with an anti termite system.


If you have any construction plans, please make sure, that your builder is a official company with registered architects and engineers and that they understand which grade they are using. A lot of companies say, they build with A grade but in reality they use C grade to make more money. If you already in building stage, please scroll up to Quality and Safety Control and make sure, you really get what you pay for and your building is legal and registered and the local office. 


Some companies say, your building does not need to be legalized or registered by the office, if you build in the outskirts. This is simply not true and you may lose your house or have to pull it down.


If you don't want to have any problems with your future house, please contact us now and let's start designing and building your dream house.
