What Summerhouse24 does

Summerhouse24 is the trading brand of Hansa Garden Ltd, a UK-incorporated private limited company that designs, manufactures and sells prefabricated timber garden buildings directly to UK consumers. Its product portfolio centers on summer houses, garden rooms, log cabins, garden offices, sheds, garages, saunas, BBQ huts, gazebos and granny annexes, with 300+ models priced from approximately £3,350 to £25,875+. Core manufacturing technology is a tongue-and-groove interlocking wall system using slow-grown Nordic spruce and thermowood pine sourced from Finland, Sweden and Estonia, with pressure-treated foundation timbers, metal strengthening rods and concealed storm braces for structural integrity.

The company operates a factory-direct go-to-market model from its principal site at Heathfield Industrial Estate, Newton Abbot, Devon, supported by two physical display sites (Devon and Leeds, with the Leeds location embedded in a Klondyke Group Garforth Garden Centre partnership) equipped with VR visualization. Revenue is generated through one-time unit sales of buildings, optional professional in-house installation services across the UK, a bespoke/custom manufacturing service carrying a 10-20% premium, and accessory add-ons such as insulation kits and roof coverings. Distribution is primarily via the summerhouse24.co.uk e-commerce site with callback/enquiry functionality, complemented by the display sites and sister e-commerce brands in nine European countries (Hansa Garden, Hansa24, Aiamaja24, Træhytter24, Casetas de Jardín 24). The company has sold 10,500+ structures over 20+ years, holds a 5-star Trustpilot rating, and is Good Business Charter accredited; it is privately held and bootstrapped with no disclosed institutional funding.
