Single Storey Extensions in Hertfordshire

Professional single storey extension across Hertfordshire — free survey, fixed written quotes and guaranteed work.

S&K Property Investments & Improvement provides professional single storey extension across Hertfordshire, backed by a proper survey and a fixed written quote.

We keep sites clean, schedules honest and communication clear from start to finish. Single-storey extensions are the quickest way to open up a home — a bigger kitchen-diner, a family room or a utility and boot-room. We build rear, side-return and wrap-around extensions with the glazing, rooflights and open-plan layout that make them work.

Our single storey extensions service in Hertfordshire includes

  • Rear, side-return and wrap-around extensions
  • Bi-fold and sliding doors, lanterns and rooflights
  • Open-plan kitchen-diner and family-room layouts
  • Underfloor heating and rewiring where needed
  • Flat (EPDM/GRP) or pitched roof options
  • One team, one fixed quote

We take care of foundations, cavity walls, flat or pitched roofing, and the internal fit-out. Whether you want bi-fold doors onto the garden or a lantern rooflight flooding the room with light, everything is priced up front and delivered by our own trades.
