The best interior design software

Interior design software has become more and more accessible, especially as people turn to building their own homes, especially to implement green initiatives and other eco-friendly designs. that they could not apply to a normal modern home.

Computer-aided design was once the exclusive domain of engineers and architects, but not now, and there is a wide range of easy-to-use applications that allow you to accurately model a building and its interior in 3D.

Through virtual tours, obvious problems can be identified, costs better controlled and several options compared.

These tools might not make you an architect or identify load-bearing walls, but they allow those with a creative flair to explore interior space and how it could be best used.

Here are the best interior design software platforms we’ve found that can effectively redesign rooms, allowing real changes to happen sooner rather than later.

1. Ultimate virtual architect

Software that does not require a real architect to be used

Reasons to buy

+Easy to use+Metrics for insight and analysis

Reasons to avoid

Telephone support is a gouge

To give the full title of this software, it is Ultimate Virtual Architect House design with landscaping and terraces. This title alludes to the scope of the Nova Development tool. It is not limited to the interior spaces but also manages the exterior spaces and the transition zones between them.

A typical user may be redesigning internal spaces, or designing extensions to existing buildings, or a completely new home or office.

To reduce the designer’s workload, Virtual Architect uses a series of wizard-based processes that can add landscaping doors, windows, kitchens and bathrooms, and even garden ponds.

It comes with a substantial library of commonly used items that include sinks, showers, tubs, seating, lighting, fountains, waterfalls, barbecue grills, and patio furniture. There are even over 7,500 plants in the system, with additional information on lighting and watering requirements available.

Another special feature is the ability to capture furniture and upholstery using a camera and then have them appear in newly designed rooms.

2. 3D architect

Inexpensive virtual planning

Reasons to buy

+Cheap and cheerful+Excellent support content+2D and 3D output

Reasons to avoid

Plants are the ones common in America

Avanquest Software sells a wide range of productivity tools for home and business use, and 3d architect is available in seven different flavors that cover a wide range of home improvement and development projects.

One of the uses of this tool is to help design interior decorating projects, where you might want to make changes and see what a room will look like with a new color scheme or layout.

With the room layout fully defined, furniture can be dragged and dropped into it, then accurately represented for a specific time of day.

It’s easy to explore new palettes, fabrics, flooring, and shades, as the system has thousands of different ones to apply.

After you make the changes, the system estimates the cost of the upgrade, based on floor and wall areas and items added to each room.

But these activities only scratch the surface of what Architect 3D can do. Depending on the version chosen, it can also provide landscape modeling, design swimming pools and terraces, place security cameras and motion detectors, design fireplaces and home theaters.

There are different versions available, but we recommend getting Gold or better as you get a lot of extra features over Express and Silver for a modest additional amount of money.

3. DreamPlan

Interiors and exteriors in one package

Reasons to buy

+Easy to use+PC and Mac+Really cheap

Reasons to avoid

Limited object libraryThe visuals seem dated

Not everyone is looking to redevelop a place for thousands of people or to renovate a French chateau, and for much smaller projects. Dream plan maybe perfect.

It doesn’t have the exotic features of more expensive tools, but it does include all the essentials that let you model a building, create floor plans, and experiment with interior design options.

The software can also handle the remodeling of an existing room with modifications to walls and windows. And, it can also be used outdoors on landscaping exercises.

Our only reservations are that the furniture library is very limited and that the 3D visuals it creates appear dated compared to other photo-real tools.

The lighting of the rooms is not calculated with precision, and the representation of colors and textures is very basic. Unfortunately, he also does not estimate the costs of the proposed changes.

But, if you want to make plans quickly and use them to scale out some room changes, then DreamPlan won’t have much impact on the budget to use.

4. Chief Interior Architect

A professional tool for business users

Reasons to buy

+Professional outing+Ray tracing visuals+Precise models and textures

Reasons to avoid


The difference between Chief Interior Architect and some of the cheapest interior design tools are huge. This solution was designed for construction professionals to create accurate designs and costs that won’t leave them out of pocket or with a delivery deadline.

To achieve this, the creators included a substantial library of cabinets, appliances, doors, windows, countertops and flooring, all based on branded items. These products are precisely modeled, allowing finished designs to be as close to conceptual visuals as one might reasonably expect.

If what you need is not in the thousands of items included, then it can be modeled for inclusion and that part stored for future reuse. Buildings can be modeled using 2D wall elevations, house plan views, or 3D right from the start.

Once the structures of the room are defined, it can be furnished and practically painted to reflect the completed renovation. A completed project can generate virtual tours and 360 degree views that can be freely distributed online for others to see.

The designs and visuals created by this software are some of the best we’ve seen and could easily tell the difference between a designer getting a renovation contract and not.

Having such great tools comes at a cost, however, and it’s a pretty expensive option.

5. 3D space designer

The last frontier of interior design

Reasons to buy

+Online application+Models presentable on the web

Reasons to avoid

Slow, even on a powerful PCLimited complexity

3d space designer is a cloud-based floor planning app for creating architectural spaces and sharing those designs online.

Without the need for an installed application, Space Designer 3D can run on any operating system with a compatible browser and be accessible from any computer connected to the Internet.

The online tool allows you to create walls, floors and roofs. Then take these rooms and fill them with furniture, then decorate digitally. The resulting models can be browsed in real time and distributed for anyone to experience web plugins.

Where other packages cater to builders and homeowners, this one is better suited for real estate marketing and event planning. Because it is online, the level of complexity of the model is limited and the moving visuals are not photoreal, but you can render them as still images.

These are easily good enough to present a change plan or event proposal.
