Best Landscape Design Software in 2026: 7 Programs Compared

What to Look for in Landscape Design Software

A good landscape plan is more than a pretty picture. It has to fit the real lot, the real slope and the real house, otherwise the terrace ends up too low, the path too steep or the new bed in the shade of a wall you forgot. These are the points that matter most when you compare programs:

• Terrain: most lots are not flat. The software should model slopes, hills, terraces and retaining walls with exact heights, ideally with contour lines.
• The house in the same model: doors, windows, floor heights and the terrace level decide where paths, steps and decks can go. A program that also plans the house avoids guesswork.
• Exact dimensions: a landscaper, a deck builder or a paving crew needs real lengths and heights, not a rough sketch.
• Object library: plants, trees, hedges, lawns, paving, fences, pergolas and outdoor furniture should be ready to place.
• 3D view and walkthrough: you understand a garden only when you see it at eye level.
• Costs: several professional landscape programs are sold as subscriptions. For a single private project, a one-time purchase is usually far cheaper.

Garden-Only Tools vs. Planning the House and Lot Together

The biggest difference between the programs in this list is what they actually model. Many landscape tools treat the house as a backdrop: a photo, a simple outline or an exterior shell. That is fine for planting design. As soon as you plan a new house, an addition, a terrace on a slope or a deck with steps down to the garden, you need the house and the terrain in one model, because every height depends on the other.

1. Plan7Architect: Best Overall Landscape Design Software for House and Garden

Price: $259.99 Original price was: $259.99.$169.99Current price is: $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 the house, the terrain and the garden in one project

Plan7Architect is a house planning program with complete terrain and garden tools built in. You start with the lot, shape the ground, place the house and then design everything around it: terraces, decks, paths, driveways, lawns, flower beds, hedges and trees. Every change is visible in 2D and 3D at the same time, so you always see how the garden works with the building.

Terrain Modeling for Sloped Lots

Few lots are perfectly flat, and that is exactly where many garden apps stop. In Plan7Architect you model the terrain with contour lines and height points, raise or lower areas, create flat surfaces for a patio or a driveway and plan hills, terraces and retaining walls with exact heights. The house and its foundation sit on this terrain, so you see right away whether the terrace door, the garage entrance and the garden steps work on your slope. The video Terrain Modeling with Plan7Architect shows the workflow.

Plants, Paths and Garden Objects

The extensive object library contains everything you need for a backyard or front yard:

• Trees, bushes, hedges and plants
• Lawns, flower beds and raised beds
• Paths, paving stones and driveways
• Ponds, fountains and other water features
• Fences, garden walls and gates
• Pergolas, garden sheds, greenhouses and outdoor furniture
• Outdoor lighting

Every element can be customized, saved to the catalog and reused in later projects. If you are missing something, you can also import models from the SketchUp 3D Warehouse. Our guide 3D CAD Garden Planning walks through a complete garden step by step.

Decks, Terraces and the House in One Model

Because Plan7Architect is a full house planning program, you do not draw the house as a backdrop. Walls have real thicknesses and heights, windows and doors create their openings automatically, and roofs are constructed automatically. Decks, terraces, balconies, railings and stairs connect directly to the building. With the timber construction tools and custom beam structures you can also plan a pergola, a carport or a covered terrace. Unlimited buildings fit in one project, so the garage, the garden shed and the main house share the same lot.

All building tools at a glance:

• Terrain modeling with contour lines and sloped lots
• Decks, terraces, balconies, railings and garden objects
• Automatic roof construction for gable, hip, shed, flat and mansard roofs, including dormers
• Foundation planning, stairs and unlimited floors and buildings
• Timber construction tools and custom beam structures
• Automatic dimensioning and exact entry of lengths, angles and distances, in imperial or metric units
• Detailed layer management and plan variants

3D Walkthrough, Renderings and Plans

You can walk through the garden in 3D at any time and check the view from the terrace, the kitchen window or the street. For photorealistic images and videos, you export the model to Twinmotion with all textures included. For the building department, a contractor or your landscaper, you create sections, elevations and plan sheets with title blocks, print them to scale, save them as PDF or export them as DWG/DXF.

Pricing

Plan7Architect Pro costs $259.99 Original price was: $259.99.$169.99Current price is: $169.99. once and can be activated on up to 3 PCs. For comparison: three years of Vectorworks Landmark at the regular price cost $4,590, three years of VizTerra cost $3,086 including the setup fee, and three years of PRO Landscape+ cost $2,700.

2. Realtime Landscaping Architect: Best Dedicated Landscape Program with a One-Time Price

Price: $599 one-time purchase (Realtime Landscaping Pro: $279)
Platform: Windows
Best for: homeowners and landscape designers who focus on the outdoor design

Realtime Landscaping Architect is one of the most complete pure landscape programs. It has six terrain tools including a contour tool, a deck wizard with curved decking and railings, a pool wizard, a library with more than 7,400 plants and plan drawings that can be printed to scale. Like Plan7Architect, it is sold without a subscription.

Its focus is the yard. Houses are modeled with a house wizard as exteriors only, so interior layouts, floor plans and permit drawings for the house itself are not part of the program. The product page lists DWG and DXF import, but no CAD export.

3. Vectorworks Landmark: Best for Professional Landscape Architects

Price: $1,530 per year
Platform: Windows and Mac
Best for: landscape architecture firms that work with survey data, BIM and construction documents

Vectorworks Landmark is a professional BIM and CAD program for landscape architecture. It handles survey data, site analysis of slope and drainage, smart hardscape and planting objects, plant schedules and complete construction documents, and it exchanges DWG, IFC and RVT files with other consultants.

For a private garden or a small builder, it is a lot of program: the subscription costs $1,530 every year at the regular price, and it takes considerable time to learn before you produce a complete plan.

4. SketchUp: Best for Free-Form 3D Modeling of Outdoor Spaces

Price: free web version for personal use; Go $129 per year; Pro $399 per year
Platform: browser; Pro also on Windows and Mac
Best for: users who like to model every detail of a garden structure themselves

SketchUp is quick to learn for simple 3D shapes, and the 3D Warehouse offers countless trees, furniture and garden objects. Many designers use it to model pergolas, outdoor kitchens or a raised bed in detail.

For landscape plans, everything is geometry you draw yourself. Terrain is shaped with manual sandbox tools, there is no plant or paving logic, and dimensioned plans need LayOut, which is only included in the paid desktop plans. See our SketchUp alternatives comparison for details.

5. VizTerra by Structure Studios: Best for Outdoor Living Sales Presentations

Price: $97 per month or $997 per year, plus a one-time $95 setup fee
Platform: Windows
Best for: landscape and outdoor living contractors who present designs to clients

VizTerra is made for contractors who design and sell hardscapes, wood decks, pergolas, outdoor kitchens and fire pits. Its 3D images and video presentations are strong sales tools, and the subscription includes training, libraries and support.

For a homeowner, the yearly subscription is the main hurdle, and pools are only included in the more expensive Pool Studio plan at $1,497 per year. VizTerra is built for the outdoor space, not for planning the house itself.

6. PRO Landscape+: Best for Landscape Contractors Who Need Proposals

Price: $90 per month or $900 per year
Platform: desktop software with mobile companion apps for iOS and Android
Best for: landscape businesses that combine design, photo imaging and estimates

PRO Landscape+ combines photo imaging, landscape CAD, 3D rendering, a plant library and proposal and estimating tools. AI functions can remove existing landscaping from a photo or generate patio and paver ideas, and it connects with QuickBooks Online and Jobber.

It is clearly a business tool. Private users pay for estimating and proposal features they do not need, and it is not a program for planning the house itself.

7. iScape: Best App for Quick Ideas on a Photo of Your Yard

Price: free basic version; Pro $29.99 per month or $299.99 per year
Platform: iPhone, iPad, Mac and Apple Vision
Best for: homeowners who want to try plant and paving ideas on a photo

iScape lets you design on a photo of your own yard or in augmented reality, start from templates or Street View and share designs with contractors. For quick ideas on a tablet, it is fast and fun.

The free version saves only two designs and offers one texture per category. Exact dimensions, terrain and plans for building something are not what the app is made for, and it is not available for Windows.

How to Choose the Right Landscape Design Software

• You plan a new house, an addition or a terrace on a slope: choose Plan7Architect, because the house, the terrain and the garden are in one model.
• You only design the yard around an existing house and want a one-time price: Realtime Landscaping Architect or Plan7Architect.
• You run a landscape architecture firm: Vectorworks Landmark, if the subscription fits your budget.
• You sell outdoor living projects or need proposals: VizTerra or PRO Landscape+.
• You want a quick idea on a photo: the free version of iScape is enough.
