Ideal Home published a new guide on April 15 that turns a budget home extension into a checklist of cost cuts, from staying small to phasing the build. (idealhome.co.uk) The guide says the first savings come from reducing floor area, keeping the design simple, using standard materials and buying second-hand where possible. It also recommends reusing kitchen units, mixing fittings, and leaving some finishes raw rather than paying for extra layers of decoration. (idealhome.co.uk) Ideal Home’s broader cost guide puts a single-storey extension at about £1,800 to £3,000 per square metre in the United Kingdom, with side returns at £2,500 to £3,500 per square metre and wraparounds at £2,300 to £2,800 per square metre, before value-added tax. The site says London projects usually land near the top of those ranges. (idealhome.co.uk) That pricing explains why the article focuses on choices that cut labour and structure costs first. Ideal Home’s extension guides say groundworks, foundations, the floor slab, and the roof are among the expensive parts that do not disappear even on a modest build. (idealhome.co.uk) The planning route can also change the bill. Planning Portal says many house extensions in England can go ahead under permitted development rights if they stay within set limits and conditions, avoiding a full planning application, while larger single-storey rear extensions can use prior approval up to 8 metres on detached houses and 6 metres on others. (planningportal.co.uk, planningportal.co.uk) Ideal Home’s advice lines up with that system by steering readers toward simpler forms and early planning. Its step-by-step extension guide says homeowners should settle the brief, budget, architect, builder, permissions, project management and ordering schedule before work starts, because late changes can push projects off budget. (idealhome.co.uk, idealhome.co.uk) The site’s week-by-week planner breaks a typical single-storey extension into roughly 14 weeks of on-site work, from site preparation and groundworks through roofing, windows, plastering, second fix and snagging. That timeline helps explain another budget tactic in the new guide: doing the project in phases instead of paying for every finish at once. (idealhome.co.uk) Ideal Home has been building this argument across several recent articles. A March 3, 2025 guide on budget kitchen extensions said not to build more than needed, to use permitted development where possible, and to favor standard materials over bespoke choices. (idealhome.co.uk) The takeaway from the new guide is narrow but practical: on a tight budget, the cheapest extension is usually the one with less square footage, fewer custom details, cleaner planning, and a schedule that lets non-essential finishes wait.
