Extensions in and around Chichester

We cover Chichester and the postcode districts PO18, PO19. The same team covers Bognor Regis (6 miles), Emsworth (7 miles), Littlehampton (11 miles), Worthing (18 miles), all within easy reach.

Just over the Hampshire border, Havant is about 9 miles away. In the South East, plenty of houses have already been extended once, which makes checking the remaining permitted development allowance an important early step.

What is included

  • Foundations, walls and insulated perimeter roof
  • Design of piers, roof perimeter and lantern proportions
  • Aluminium or timber lantern and full-height glazing
  • Heating sized for the glass area
  • Thermal calculations where glazing is generous

Planning rules that apply in Chichester

In England a glazed or orangery-style extension follows the same size limits as any single-storey rear extension: 3 m or 4 m without an application, or up to 6 m and 8 m through prior approval. Building regulations limit glazing to about a quarter of the new floor area plus the openings it replaces, unless whole-house calculations show the design still performs.

Homes in conservation areas, national parks, National Landscapes (formerly AONBs), the Broads and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.

Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.

Applications are decided by the local planning authority (your district, borough or unitary council).

Common questions in Chichester

Who do I contract with for an orangery extension in Chichester?

Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.

Will my neighbours in Chichester be involved?

If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.

How long does an orangery extension take to build in Chichester?

On site, typically 10 to 16 weeks once approvals are in place. Before that, allow 6–12 weeks design and approvals.

Will an orangery be too hot in summer?

Not if it is designed with solar-control glass, a solid perimeter and ventilation. We size the lantern and opening vents with that in mind.

How much does an orangery cost?

Our guide range is about £2,690 to £5,040 per m² including VAT, so a 16 m² standard-spec orangery is typically £50,000 to £63,000 in Chichester.
