Ready to Plan Your Next Project?

Every tool on this site is free to use, right in your browser — start with whichever step you're on right now.

Chhimwal brings together eleven free, browser-based construction and home-design tools — everything you need to plan, budget and visualise a project without downloading a thing.

Free online construction tools for every stage of a build

Planning a home is a series of decisions, and each one is easier when you can test it before you commit money to it. That's the idea behind Chhimwal: a single place where a homeowner, builder or DIY enthusiast can sketch a floor plan, run a construction cost estimate, arrange furniture, preview paint colours and lighting, and plan a garden — all for free, all in the browser, and all on any device.

Professional design and estimating software is powerful but expensive and steep to learn. Our tools take the handful of jobs most people actually need and make them simple, visual and instant. There's no account to create, no watermark on your work, and nothing to install unless you want to add Chhimwal to your home screen as an app.

Plan & design

Draw floor plans in 2D and 3D, arrange furniture and calculate room dimensions.

Budget accurately

Estimate the cost to build or renovate and analyse where your energy money goes.

Visualise finishes

Mix paint colours and preview lighting so you buy the right shade the first time.

Design outdoors

Lay out gardens and yards and stage rooms to show a space at its best.

Why choose Chhimwal's home design tools

Every tool on the site is built around the same principles: it should be free, it should work instantly in your browser, and it should give you something useful you can act on. Whether you're pricing a new build, deciding where the sofa goes, or choosing a wall colour, you get a fast, visual answer without spreadsheets, software licences or sign-up forms.

Because the site works as a Progressive Web App, you can also install Chhimwal on your Android phone or iPhone straight from the browser. Once installed it opens full-screen like a native app and works even when your connection drops — handy on a building site or in a half-finished room where signal is patchy.
