Space planning is one of the most technically demanding sectors of interior design practice. Before a single piece of furniture is selected or a colour palette is finalised, the layout of a space must work functionally, proportionally, and in relation to how people will move through and use the space.
The space planning software you use to develop and communicate that layout matters more than many designers realise, particularly when it comes to presenting ideas clearly to clients and collaborating with builders, contractors, and architects.
The market for space planning software has expanded considerably in recent years, with powerful free options that were unavailable a decade ago, alongside professional-grade platforms that have become industry standards in studios of all sizes.
Knowing which space planning tools are worth your attention, and which ones suit your current stage of practice, will save you miles of frustration and a whole lot of money.
This article covers the most widely used tools available today. They are organised by price tier, so you can make a well-informed decision about where to invest your time and money.
What to Look for in Space Planning Software
Before diving into specific platforms, it is worth identifying what good space planning software needs to do. At a minimum, it should allow you to draw accurate floor plans to scale, place (and manipulate) furniture and fixtures, and export or share your work in a format that your clients and contractors can read easily.
Beyond the basics, the features that tend to matter most in practice are:
- The quality and depth of the furniture and object library.
- The ability to switch between 2D and 3D views.
- The ease of producing presentation-ready visuals.
- Possessing virtual tour abilities.
- Whether the platform supports collaboration or client sharing.
Some designers also prioritise cloud-based access, so they can work across devices or share files without manually exporting them.
Technical precision matters too. A tool that produces attractive visuals but cannot keep accurate dimensioning is useless in a professional context. Space planning is not just about aesthetics, but also about a buildable layout, ensuring circulation routes meet minimum requirements, and that the design can be handed off to a contractor, with the confidence that the designs are clear and easy to follow.
Free Space Planning Software Worth Using
1. RoomSketcher
This offers a free tier that lets designers draw floor plans, place furniture, and generate basic 3D views. It is browser-based, requires no installation, and has an interface accessible to clients. It is a useful tool for initial briefing sessions or for giving clients a way to sketch out their existing space before a first meeting. The free version has limitations around the number of projects and the quality of exported images, but for early-stage planning and client communication, the software performs well.
2. Planner 5D
The space planning software is primarily aimed at homeowners and beginners. It has a free tier for concept-stage planning and client presentations. It offers both 2D and 3D modes, has a reasonable furniture library, and possesses the ability to take virtual walkthroughs of interior spaces.
Planner 5D is not a precision tool, and it is not suited to technical documentation. It is only good for communicating a layout concept to a client in an accessible visual format. For this, it is very effective.
3. AutoCAD Web (Free Version)
Autodesk offers a free browser-based version of AutoCAD that supports basic 2D drawing. It is much more limited than the full desktop application, but if you are already comfortable with AutoCAD’s interface and only need a lightweight option for simple plan work, it is a good choice. It is particularly useful as a no-cost entry point for students and recent graduates who want to maintain familiarity with AutoCAD workflows without paying for a full subscription.
4. SketchUp Free
SketchUp’s free browser-based version gives you access to 3D modelling on a platform widely used for architecture, interior design, and product design. The free tier restricts access to its full template library and some export options, but you can still find the core modelling tools useful. If you want to develop three-dimensional spatial concepts and are comfortable with going through a steeper learning curve, SketchUp Free is one of the strongest, no-cost options available.
Paid Space Planning Software for Professional Use
1. AutoCAD (Full Subscription)
This software is still the industry standard for technical drawing in architecture and interior design. Its precision, compatibility with contractor and architectural workflows, and its functionality make it the benchmark against which other tools are measured. For designers working on commercial projects, large-scale residential work, or any context where technical documentation must meet professional standards, AutoCAD is ranked among the best. It is not the most intuitive tool for beginner users, and its subscription cost is high, but investing in it is justified for work where technical accuracy and file compatibility are non-negotiable.
2. Vectorworks Architect
Vectorworks is widely used in interior design and architecture, particularly in the UK and Europe. It offers a combination of 2D drafting, 3D modelling, and BIM capabilities and is generally considered more accessible than AutoCAD for designers without an architectural background. Its presentation output, particularly rendered floor plans and elevations, is of a high standard.
For interior designers who want professional-grade capabilities (without the technicalities of AutoCAD), Vectorworks is an alternative worth evaluating.
3. Chief Architect
Chief Architect is popular among residential interior designers and design & build professionals. It automates a significant portion of the drawing process, generating elevations, sections, and material schedules from a 3D model. This capability makes it faster to produce construction documentation than in platforms where everything must be drawn manually. Its rendering process produces high-quality visuals that are suitable for client presentations. Its library of furniture, fixtures, and materials is extensive.
Chief Architect software is best suited for residential work. It is less commonly used in commercial or hospitality designs.
4. SketchUp Pro
The paid version of SketchUp unlocks the full desktop application, advanced export options, access to the 3D Warehouse’s complete library, and integration with LayOut (Autodesk’s companion tool for producing professional construction documents and presentation sheets directly from SketchUp models). For interior designers who have become proficient with SketchUp Free, the upgrade to Pro is a natural next step. It is particularly well-suited for designers who work on both concept visualisation and technical documentation.
5. Revit
Revit is the leading BIM platform and is most used for large commercial, hospitality, or multi-unit residential projects where multiple disciplines (architecture, structural engineering, mechanical & electrical services) need to work from a shared model.
For interior designers working in large project teams on complex builds, familiarity with Revit is expected. For sole practitioners or small studios working primarily on residential projects, the learning curve and subscription cost are unlikely to be justified.
Using the Right Software for Your Stage of Practice
The right tool depends heavily on where you are in your career and what kind of work you are doing. A student or recent graduate building their first portfolio has different needs from an established practitioner running a team and delivering commercial projects.
If you are a beginner just starting your career, RoomSketcher or Planner 5D will give you all you need to produce clear, presentable layouts without any financial outlay. As your career progresses and your projects become more demanding, technically, moving to SketchUp Pro or Vectorworks will give you the precision and output quality that more professional work demands. If you are working in commercial interiors or alongside architects and contractors on complex building projects, AutoCAD or Revit may be necessary to integrate properly with the wider project team.
It is worth noting that many designers use more than one tool: a fast, intuitive platform for early concept development and client communication, and a more precise technical tool for documentation. There is no requirement to commit to a single piece of software for every stage of a project.
Whichever platform you choose, proficiency matters more than the tool itself.
A designer who knows their software thoroughly will produce better work than one who uses a superior platform they haven’t mastered properly.
Invest time in training, make use of the tutorial resources most of the platforms provide, and continue to build your technical skills as intentionally as you build your design skills.
