Garden annexes have revolutionised suburban living in SM4, particularly where Victorian terraces meet post-war estates. Those generous plots common around Morden Park present perfect opportunities for self-contained structures. Local planning attitudes have shifted significantly, making these additions more achievable than many homeowners realise.
Construction begins with understanding your garden's unique characteristics - from clay-heavy soil typical near St Helier to drainage considerations affecting Lower Morden properties. Modern SIPs panels create thermally efficient shells within weeks, while careful positioning maximises natural light without compromising privacy. Electrical connections, plumbing routes and insulation specifications all factor into creating year-round comfortable spaces.
Twenty years building across South London means knowing which planning officers appreciate thoughtful design. Morden homeowners value craftsmanship that respects neighbourhood character whilst delivering contemporary functionality.

Basic insulated structures start around £15,000, while fully-fitted annexes with bathrooms typically range £25,000-£45,000. Bespoke designs featuring kitchenettes or premium finishes can reach £60,000, depending on size and specification.
Absolutely - from compact gardens near Morden tube station to spacious plots bordering Morden Hall Park. Recent projects include contemporary studios in St Helier and traditional-style retreats overlooking Lower Morden's green spaces.
Groundworks and base preparation usually take 7-10 days, followed by 2-3 weeks for structure assembly and weatherproofing. Interior fit-out adds another fortnight, meaning most annexes welcome their first occupants within 6-8 weeks of breaking ground.
Every structure carries decade-long coverage against defects - from roof integrity to thermal performance. This encompasses all structural elements, weather resistance and installed systems, providing peace of mind long after completion.
Definitely - modern macerator systems eliminate extensive groundwork, while careful routing minimises garden disturbance. Connection points are planned during base construction, keeping installation swift and your existing garden largely undisturbed.
