7 Best Plan7Architect Alternatives in 2026 (Honest Comparison)

If you want to plan a complete house yourself, Plan7Architect remains the best value: no alternative in this comparison combines object-based walls, roofs and stairs, automatic sections and elevations, permit drawings and DWG/DXF export with a one-time price of $169.99. The strongest alternatives are Chief Architect Premier for professional residential designers, Cedreo for home builders who sell with fast renderings, SketchUp for free-form 3D modeling, and Sweet Home 3D as the best free tool for furnishing rooms.

Most people who search for Plan7Architect alternatives are close to buying house planning software and want to be sure they pick the right one. That is a smart step, because the programs below work in very different ways and their prices range from free to several thousand dollars per year. Below you will find 7 real alternatives with their current prices, what each one does well, and where it fits better or worse than Plan7Architect for a house project.

Plan7Architect Alternatives Compared

Why People Compare Plan7Architect with Other Programs

House planning software is an investment of time as much as money. Once you have drawn your first floors, you want to finish the project in the same program. That is why most buyers look at the well-known names before they decide. These are the questions behind most comparisons:

• Is a subscription worth it? Many architecture programs are now sold only on a yearly basis. Buyers want to know what they get for $400 to $3,000 per year compared with a one-time license.
• Can a free tool do the job? Free programs are great for trying out room layouts, and many people want to know where they stop being enough for a real house.
• Which programs create permit drawings? A nice 3D view is not enough when the building department, the builder or the engineer needs floor plans, sections and elevations to scale.
• How hard is it to learn? Professional CAD and BIM programs are powerful, but they are made for people who use them every day. Self-builders want results without months of training.

One-Time License vs. Subscription: What a House Project Really Costs

The biggest difference between Plan7Architect and most professional alternatives is the pricing model. A house project rarely ends after a few weeks: you plan, discuss the design with your family and your builder, make changes during the permit process and often come back to the plans years later for a remodel or an extension. With a subscription, you pay for every one of those years. This is what the programs in this comparison cost over three years:

The second difference is how you work. Plan7Architect is object-based: you plan with real walls, floors, ceilings, roofs, stairs and foundations instead of drawing lines. Chief Architect Premier, Cedreo, Archicad and Revit work in a similar way, while SketchUp is a general 3D modeling program where walls and windows are geometry you build yourself. For a broader overview of many more programs, see our software comparison page.

Plan7Architect: Best Overall Value for Planning a Complete House

Price: $169.99 one-time purchase, lifetime license, no subscription
Platform: Windows desktop software
Best for: homeowners, self-builders, contractors and designers who want to plan a complete house, from the first floor plan to permit drawings

Before you look at the alternatives, it helps to know what you are comparing against. Plan7Architect is a dedicated house planning program made for people without CAD experience. You draw a wall, and it has a thickness, layers and a height. You place a window or a door, and the opening is created automatically. The floor plan, the 3D model, the sections and the elevations are synchronized, so every change appears everywhere at once.

Everything for the Building Itself

Plan7Architect covers the parts of a house project that simple room planners skip:

• Automatic roof construction for gable, hip, shed, flat and mansard roofs, including dormers
• Terrain modeling with contour lines and sloped lots
• Foundations, slabs, floors, ceilings, stairs and beams
• Timber construction tools and custom beam structures
• Electrical, heating and plumbing planning
• Decks, terraces, balconies, railings and garden objects
• Unlimited floors and buildings in one project, plan variants and detailed layer management
• Living and usable area calculation

Exact Plans Without Drawing Line by Line

You enter exact lengths, angles and distances, and the dimensions are created automatically. Guide lines and virtual walls help you lay out rooms and zones, and you can switch between imperial and metric units at any time. Every element can be customized, saved to the catalog and reused in your next project, from a special wall structure to your own window type.

Permit Drawings and Files for Your Architect

Sections, elevations and plan sheets with title blocks are created from the same model. You print them to scale, save them as PDF or exchange them as DWG/DXF files with your architect, engineer or builder. Our guide on creating construction drawings for a permit shows the steps.

3D Walkthrough and Photorealistic Renderings

You can walk through your house in 3D at any time and furnish it from an extensive object library, including models imported from the SketchUp 3D Warehouse. For photorealistic images and videos, you export the model to Twinmotion with all textures.

Pricing

You buy Plan7Architect Pro once for $169.99 and can activate it on up to 3 PCs. That is less than half of one year of SketchUp Pro and less than one month of Chief Architect Premier at the monthly rate of $229.

1. Chief Architect Premier: Best for Professional Residential Designers

Price: $1,995 per year or $229 per month
Platform: Windows and Mac
Best for: residential designers and builders who produce construction documents every day

Chief Architect Premier is one of the most complete residential design programs on the market. It has automatic building tools, framing, detailed construction documents, cabinets and a huge library, and it is made for professionals who design many houses per year.

For a single house or a small company, the subscription is the main hurdle. After one year you have paid more than ten times the price of Plan7Architect Pro, and the program has a longer learning curve. Read our detailed Chief Architect alternative comparison if you are deciding between the two.

2. Cedreo: Best for Home Builders Who Sell with Renderings

Price: free plan for 1 project; Personal $139 per project; Pro from $79 per month billed yearly or $129 month to month
Platform: browser-based
Best for: home builders, remodelers and sales teams who need quick floor plans and renderings for clients

Cedreo runs in the browser and is built for speed. Builders can draw a floor plan, generate a 3D model with automatic roofs and produce attractive renderings within a short time. Sections and elevations are generated from the house model, which helps in sales meetings and early design discussions.

For self-builders, the pricing is the weak point: the free plan covers one project with watermarked renderings, and the professional plans are billed monthly. The export formats listed on the Cedreo website are images and PDF, so exchanging DWG files with an architect is not part of the workflow. See our Cedreo alternative page for a closer look.

3. SketchUp: Best for Free-Form 3D Modeling

Price: free web version for personal use; Go $129 per year; Pro $399 per year
Platform: browser, Windows and Mac (desktop with Pro)
Best for: concept models, furniture, woodworking and quick massing studies

SketchUp is easy to start with and very flexible. You can model almost anything, and the 3D Warehouse offers millions of free models. For concept designs and custom details it is a popular tool.

For a house plan, SketchUp means manual work: walls are drawn as geometry, openings are cut by hand, and sections and plan sheets are set up in LayOut, which is only included in the Pro plan. Our SketchUp alternative page explains the difference in detail.

4. Archicad: Best BIM Software for Architects on Mac and Windows

Price: Archicad Studio $2,414 per year; Archicad Collaborate $2,840 per year
Platform: Windows and Mac
Best for: architecture firms that work with BIM

Archicad is a mature BIM program with intelligent building elements, excellent documentation tools and strong teamwork features. Many architects prefer it for its design workflow and its Mac support.

For one house, it is a professional tool at a professional price. You pay more per year than most self-builders spend on their entire planning process, and it takes a lot of practice to use it efficiently.

5. Revit: Best for Large BIM Teams

Price: $3,005 per year or $380 per month
Platform: Windows
Best for: architecture and engineering firms working on large BIM projects

Revit is the BIM standard in many large firms. Architecture, structure and building services are coordinated in one model, and drawings, schedules and quantities are derived from it.

Revit is built for teams of trained professionals. For a homeowner or a small builder, the price and the complexity are far beyond what a house project needs.

6. Planner 5D: Best for Quick Room Layouts on Any Device

Price: free plan; Premium $59.99 per year; Professional $399.99 per year
Platform: browser, Windows, Mac, iOS and Android
Best for: homeowners who want to try out room layouts and interior ideas

Planner 5D is very easy to use and runs on almost every device. You can draw rooms, furnish them from a large catalog and create attractive renders, which makes it popular for interior ideas and quick layouts.

It is focused on rooms and interiors rather than on the building. There are no sections or elevations for permit drawings, the roof tools are limited, and CAD export is reserved for the most expensive plan.

7. Sweet Home 3D: Best Free Tool for Furnishing Rooms

Price: free, open source
Platform: Windows, Mac, Linux and a browser version
Best for: simple apartment and room layouts on a zero budget

Sweet Home 3D is the best-known free home design program. You draw walls and rooms in 2D, place furniture from the catalog and see the result in 3D right away. For furnishing an apartment, it is a good choice that costs nothing.

For a house project it reaches its limits quickly: there is no built-in roof tool, the ground is flat, and sections, elevations and DWG export are only available through plugins, if at all.
