House Madness

House Madness is a browser app for planning renovations, loft conversions and extensions without installing software. Key features: • Trace old drawings or import an existing floor plan • Draw your house and explore it in 3D • Plan lofts with dormers and check the usable floor area • See which walls are load-bearing and what they carry • Try cladding, decks, floors and kitchen layouts before committing • Print scaled drawings ready for permit applications • Use free stair, loft-area and built-up-area calculators The app lets you start from what already exists. Trace or import old house drawings, then build your plan on top of them. Changes can be reviewed before you accept them, so you keep control over every adjustment to walls, roof and layout. The 3D view shows how a new loft, extension or kitchen will look in practice, helping you compare options before you spend money on materials or contractors. Beyond visualization, House Madness helps you understand the structure. Identify load-bearing walls, check floor areas against local rules, and run quick calculations for stairs and built-up area. Scaled printouts make it easier to communicate with architects, builders and municipal offices. Designed for homeowners, renovation planners and small builders who want to explore ideas early. Made in Norway and suited to houses across Europe.
