Garage plans and design criteria: a useful guide with 3D examples and DWGs

How to design garage plans: the complete guide with standards, layouts, examples, projects to download together with videos

When searching for garage plansyou can find plenty of results illustrating how to arrange garage spaces or even find many ideas for “DIY” projects too.

In this insight we’ll be providing a technical guide to analyse different garage definitions, types, standards, regulations, layouts and other helpful design elements. Further on we’ll also examine models of underground, outdoor, public or private garages and highlight the minimum and recommended measures together with other important design criteria, such as safety requirements.

Layouts in the DWG format and project 3D models in the native .EDF format are available for download and to use as your free design resource reference. To open these file formats, you can download the free trial version of Edificius  and open project files and check out the various plan designs and other project documentation.

Garage plans: definition and classification

With the term “Garage” (or automated parking garage or carport) it is generally intended as a space where one or more vehicles are parked. These areas mainly refer to covered areas where motor vehicles are either repaired, serviced, parked etc. Sheds that are open on at least two sides are not considered garages.

Based on certain construction characteristics, garages can be classified:

according to the use of the building as:

  • detached, located in buildings exclusively for parking use;
  • mixed, all the rest.

according to the location with respect to the terrain as:

  • underground;
  • outdoor.

according to certain operations:

  • guarded, the one which is equipped with automatic control systems to prevent fire spread, or provided with continuous surveillance systems;
  • unguarded, all the rest.

according to the organization of internal spaces as:

  •  box garage;
  • open space.

Charging points for electric vehicles

In recent years the high innovation introduced in the automotive industry, with special regard to electric vehicles, has raised the need for electrical charging points to be installed. When designing a garage, it’s extremely important to carry out the necessary checks to ensure that a property can accommodate such charging facilities.

It is fundamental to consider the minimum dimensions for your garage project.

As seen in our previous article “Car parking design: types, examples and 3D architectural BIM model” the basic sizing of a garage  depends on the overall dimensions of a car, therefore 2,50 mt. x 5,00 mt. (8.20′ x 16.4′) for a standard garage and 3,20 mt. x 5,00 mt. (10.4′ x 16.4′)  for parking spaces for the disabled (parameters that vary a little, depending on the different national regulations).

A comfortable solution is 3 mt. x 6 mt. (9.8′ x 19.6′) for standard garage space and 3,75 mt. x 6 mt. (12.3′ x 19.6′) for parking spaces for the disabled.

Extra lateral spacing must be provided to ensure that the vehicle doors can be comfortably opened by passengers on either side.

The garage height should be at least 2,40 mt. (7.8′)

The opening measures provided should be at least 2,40 mt. (width) x 2,20 mt. (height). (7.8′ x 7.2′)

Additional elements to consider in garage plans are:

  • washable walls
  • concrete floor or oil-resistant clay tiles
  • proper lighting
  • anti-slip flooring for ramps used in underground garages
  • a rigid surface for getting on and off in front of the garage
  • a space for storing winter tires and car accessories
  • a space for storing other objects such as skis, bicycles, luggage racks, work and garden tools, etc.
  • installation of the automatic opening systems with remote control.

Careful design of walls and ceilings should not be overlooked and, most of all, it is fundamental to take in consideration that they need to be fireproof.
