  • increase your drawing output while saving on cost
  • flexible payment structure that eliminates fixed manpower rates
  • employment benefits.

The collaboration process begins with a thorough discussion of the project requirements, followed by a formal quotation that outlines the terms, stages of collaboration, and list of deliverables. Throughout the project, we maintain open communication, and discussions can take place via email, chat, or video call meetings when necessary.

Payment procedures are agreed upon during our discussions to ensure that both parties are satisfied with the agreement before commencing work. Overall, Cad Dezign offers a professional and cost-effective approach, making it easy for you to achieve your goals.

The proficiency in various software tools allows for smooth and detailed execution of projects. These tools include, but not limited to:

SketchUp 100%
Lumion 95%
Photoshop 85%
ArchiCad 85%


In order to fully understand the scope of the project, provide high-quality services, and offer a fair price, Cad Dezign takes the following steps. This approach ensures that there are no misunderstandings and that the company remains transparent.


The first step involves a comprehensive discussion between both parties to establish the project’s goals and understand the client’s requirements. During this phase, all relevant information and ideas pertaining to the project are shared and discussed. Subsequently, a quotation is prepared and submitted to the client for approval.

Proposal Drawing Development Process

After the client approves the quotation and agrees to collaborate, proposal drawings will be created based on the discussed information. Cad Dezign makes reasonable revisions throughout this process to ensure client satisfaction. The client will have the opportunity to review the drawings and provide feedback to ensure all requirements are met and the project is perfected.

Project Completion and Post-Project Service

After the completion of the project, the final product will be delivered to the client in the required file type, as agreed upon by both parties, which may include JPEG or PDF format. In some cases, additional amendments may be necessary due to changes in client preferences. Cad Dezign will always be happy to accommodate these requests, but please note that additional costs may be incurred to cover the expenses of the revisions.


“Quotation is Free of Charge!”

When it comes to architectural and interior design services, one of the most common questions is about pricing. It would be great to provide a simple answer, but the truth is that the price of every project varies depending on a number of factors.

Some of the factors that influence the price of each project are as follows:

  • Complexity and size of the project: Larger projects with more intricate designs will generally require more time, effort, and resources to complete. This means that the cost of these projects will be higher than those that are smaller and simpler.
  • Specific drawing requirements of the client: This contributes a significant impact on the pricing because some clients may have very specific ideas or requests that require additional time and effort.

Ultimately, the goal of the pricing structure at Cad Dezign is to ensure that each client receives a custom quote that accurately reflects the time and resources required to complete their project. The company believes that this personalized approach is the best way to ensure that every project receives the attention and care it deserves.

If you have any questions about pricing structure or would like to receive a custom quote for your project, please don’t hesitate to send a message with your inquiry.
