House Extension SEO
"House extension [city]", "single storey extension [city]", "double storey extension [city]" — high-value, high-volume query cluster; content covering planning permission vs permitted development, building regulations, typical costs, and party wall agreements.
Definition
House extension SEO targets homeowners planning to extend their property — the highest-value query cluster for most building companies. Query clusters: "house extension [city]", "single storey extension [city]", "rear extension [city]", "double storey extension [city]", "kitchen extension [city]". Content requirements: (1) Permitted development vs planning permission: single-storey rear extensions up to 3m (detached) or 4m (semi/terraced) are typically PD; larger extensions require full planning application; informing buyers about PD rights reduces their perceived barrier to starting; (2) Building regulations: all extensions require building regs approval (structural calculations, insulation U-values, electrical); (3) Party wall agreements: any extension within or on the boundary requires a party wall surveyor; explain the process; (4) Structural elements: RSJs for opening up walls, underpinning if extending into clay, drainage diversion; (5) Typical costs: single-storey kitchen extension £25,000–50,000 depending on spec; double-storey £40,000–80,000; (6) Timescales: planning 8 weeks, build 8–16 weeks depending on size; (7) Case study pages for completed extension projects capture long-tail location-specific searches.
Why it matters for SEO
House extension queries indicate a buyer in active planning mode with a significant budget commitment — typically £30,000–£80,000+. The search intent is strong; the buyer is researching contractors and pricing, not just gathering ideas. A dedicated extension page with planning guidance, real project examples, and transparent pricing converts at significantly higher rates than a generic "building work" page.
