Who Is the Software Made For?

I’ve used the software across several types of projects, and one thing is clear: it’s not just for architects. The flexibility of Plan7Architect makes it the perfect solution for a wide range of users.

This includes:

• Private builders and homeowners
  Planning a new home, extension, or renovation and want to visualize it in detail.

• DIY enthusiasts
  Looking to create floor plans for permits, interior remodeling, or full property designs.

• Architects and engineers
  In need of a fast and affordable way to model house projects, especially when working with private clients.

• Real estate professionals
  Creating visual walkthroughs of properties to support listings or marketing efforts.

• Interior designers
  Planning furniture layouts and design themes in an accurate 3D space.

The software adapts to different levels of experience, offering simple tools for beginners and advanced features for professionals.

Core Capabilities of Plan7Architect’s 3D House Design Software

Floor Planning in 2D

One of the most satisfying aspects is how intuitive the 2D planning tools are. You can quickly draw walls by clicking and dragging, place windows and doors precisely, and adjust dimensions with a simple right-click.

You can build single-level layouts or add multiple stories. Each level aligns automatically, and structural elements like staircases adjust accordingly.

Highlights include:

• Adjustable wall thickness

• Wall connection types (T-, L-, X-joints)

• Room naming and area calculation

• Automatic floor and ceiling generation

• Smart snapping and alignment aids

• Support for any unit system (metric and imperial)

Tip: Use the integrated layer system to separate building elements like plumbing, furniture, or electric wiring for better planning clarity.

3D Visualization in Real Time

As you draw in 2D, the 3D model updates instantly. This real-time visualization helps spot issues early—like a roof that doesn’t sit properly or a door that swings into furniture.

You can freely move through the model using the 3D camera, zoom into any room, or take a full virtual walkthrough. It’s one of the most useful features when presenting a project to someone who doesn’t understand floor plans.

3D View Modes:

Lighting and material rendering help to assess aesthetics realistically, even allowing daylight simulation to test window placements.

Interior and Exterior Design Tools

Plan7Architect includes a huge library of design objects that can be dragged directly into your plan. I found it especially helpful when working on a renovation project—I could see how existing furniture would fit in the new layout.

Available elements:

• Kitchen units, sofas, tables, beds

• Sanitary installations like bathtubs, sinks, toilets

• Lighting fixtures, shelves, decorative items

• Outdoor elements: garden furniture, fences, plants

• Cars, pools, pergolas, and garage elements

You can also import 3D models from external sources or edit existing objects in terms of size and material. Surface textures and colors can be customized freely.

Tip: If you’re working with a real interior designer, export views or screenshots from different angles to align planning decisions easily.

Units and International Use

A key reason I chose Plan7Architect is that it works seamlessly for international projects. You can create floor plans using either metric (meters, centimeters) or imperial (feet, inches) units.

The unit system can be adjusted at any point—globally for the entire project or individually per measurement. This is particularly useful if you’re working with international collaborators, suppliers, or clients who use different systems.

In one of my projects, I started in imperial units for a client in the US, then switched to metric for importing building materials from a European supplier. The conversion was handled automatically.

Benefits of Using Plan7Architect

Advantages I’ve experienced first-hand:

• No subscription: You pay once and can use the software forever

• Offline usage: No cloud dependency or data privacy concerns

• Customizable license: Use it for personal or professional projects

• Scalable: Plan simple rooms or complex multi-story buildings

• Beginner-friendly: But powerful enough for demanding designs

• Project sharing: Save, export, or print in various formats (PDF, image, DWG)

14-Day Cancellation Policy:
Instead of offering a time-limited trial version, Plan7Architect allows full access after purchase with a 14-day cancellation period, during which you can test the software risk-free. This gives you enough time to explore all features without limitations.
