Here's our pick of some of the best interior design apps currently available to home designers and interior decorators. 'Using a room planner or design app is the most accurate way of fleshing out your ideas visually,' says Cory Powell from DBS Bathrooms, who talks us through some of the best free interior design software, alongside some tried and tested apps and tools by the House Beautiful team. Regardless of what home project you're working on – and the tradespeople you choose to hire – you’ll want to communicate your ideas with everyone involved as accurately as possible, from the layout of your room to the paint colours for each space. Of course, planning, budgeting, moodboarding and the like, is essential to any home renovation project (whether you're planning an extension, new kitchen or bathroom, or finally getting round to landscaping the garden) but designing your dream space isn't as daunting as you think, thanks to plenty of professional home and interior design software that's readily available, user-friendly, affordable, and in many cases, free. It's one thing moving into a new house but it's another actually designing a home.
