Orangery, Sunroom & Conservatory - One Team, One Fixed Price

These four names get used almost interchangeably by homeowners, but they describe genuinely different structures - and the difference matters for cost, comfort and how the finished room works day to day. We build all four, and we'll tell you honestly at the free site survey which one actually fits your house rather than upselling the most expensive option.

Conservatory, Sunroom, Orangery or Glass Extension?

Conservatory — fully glazed roof and walls on a low dwarf wall. The most light, the least thermal control, and generally the lowest cost of the four.

Sunroom — the same glazed-wall approach as a conservatory, but with a solid, insulated roof. Trades some light for much better year-round comfort.

Orangery — more solid brick or render walls with corner piers, topped with a glass roof lantern rather than a full glass roof. Sits closer to a full extension than a conservatory does.

Glass extension — a fully integrated, structural-glass extension usually built as part of a kitchen extension, with frameless or slim-framed glazing and full insulation to building-regulations standard.

Glass Extension Cost in Dublin

Budget EUR 25,000 to EUR 45,000 for a conservatory, EUR 30,000 to EUR 50,000 for a sunroom, EUR 45,000 to EUR 70,000 for an orangery, and EUR 70,000 to EUR 120,000 for a full structural-glass extension integrated with your kitchen.

Which Option Suits Your Dublin Home

A conservatory or sunroom works well as an added garden room — a playroom, home office or extra sitting room — without touching your existing kitchen. An orangery suits period homes wanting brick piers that echo the existing walls rather than an all-glass box. A full glass extension is the right call when the real goal is an open-plan kitchen, dining and living space that opens straight onto the garden.

Common Questions

Quick answers homeowners ask before they book a site visit.

What's the difference between a conservatory, sunroom and orangery?expand_more
A conservatory is fully glazed - roof and walls both glass, usually on a low dwarf wall. A sunroom swaps the glass roof for a solid insulated one, trading a little light for much better year-round temperature control. An orangery sits between the two: more solid brick or render walls with piers, and a glass roof lantern rather than a fully glazed one - historically named after the orange trees they were built to house.
How much does a glass extension cost in Dublin?expand_more
Budget EUR 25,000 to EUR 45,000 for a conservatory, EUR 30,000 to EUR 50,000 for a sunroom, EUR 45,000 to EUR 70,000 for an orangery, and EUR 70,000 to EUR 120,000 for a full structural-glass extension integrated with your kitchen. See our full cost guide for how this compares to other extension types.
Do I need planning permission for a conservatory or glass extension?expand_more
The same exempted development rules apply as any rear extension - up to 40 sqm, within height limits, and not exceeding a set proportion of your garden. We confirm exemption in writing before quoting, the same as for any other extension type.
Can a glass extension be used all year round?expand_more
With the right glazing specification, yes. Cheap conservatories earned a bad reputation for being unusable in summer heat and winter cold - modern double or triple glazing, solar-control glass and proper roof ventilation solve that, which is why spec matters more than style for year-round comfort.
Can you build a glass extension onto a period Dublin home?expand_more
Yes - a contemporary glass extension at the rear is one of the most common ways to add space to a Victorian or Edwardian home without disturbing the original front elevation. See our modern extension design page for more on that approach.
