An innovative architecture is one that is modeled to respond to the needs of the client and the environment. Depending on the purpose of the project, models can be developed from a wide variety of materials, including wood, blocks, frames and paper. Different scales are used in models to display perspectives, shape, layout and details of a structure, a feat that may be difficult to attain using traditional 3D rendering or drawing. For clarity purposes, the specification information that comes with architectural design models includes; the size of the model, duration of design, build time, type of software and the number of layers used. According to White Clouds, architectural models offer a visual glimpse into how a structure will look like once it’s complete. Models serve various purposes in the design and development process, including:

1. Offers a preview of new construction
Architectures often use models to create an early representation of the complete project. The models are usually constructed using the same dimensions as the real construction, but with different scales. Through the models, stakeholders in a project can visualize the end product and make necessary amends before completion.

2. Selling and marketing real estate
Many firms and individuals understand the potent power of models as an exceptional sales and marketing tool in real estate development. Case in point, a developer can use a scaled down model to provide a vivid glimpse of a housing or office development and present it to potential clients looking to stake a claim, buy or rent the units.

3. Allows scaling of projects of various magnitude for showcasing
Developers can take advantage of the wide audiences that visit trade shows to showcase their projects using models. Through the display, stakeholders and members of the public can learn more about the project, the firms participating in the project and what to expect in future.

4. Used by homeowners and city planners to offer to build approval
In most jurisdictions, an architectural scale model may be requested by an association or city before handing over the necessary permit for construction to commence. The presented models allow the planners to look at the overall outlay of the structure to ensure it follows the guidelines of construction.

5. Tool to engage the public about a project and raise funds
Models provide a clear platform of reference, which can be used by developers to engage the public or create awareness about a project. The opinions derived from such public displays can go a long way to shaping public opinion regarding the proposed project. This strategy can also be used to raise equity from prospective investors or donors interested in the project. 

According to 3DConnexion.com, the additional benefits of using advanced architectural design models such as 3D CAD in disciplines such as engineering and architecture include ability to prevent costly mistakes; provides an opportunity to showcase creativity and it saves time. The re-emergence of model driven architecture has been enhanced by the development of sophisticated apps that can be easily uploaded on the phone and computing devices.
