Conservatory & Sunroom FAQs
A basic uPVC conservatory with a polycarbonate roof costs €8,000 to €15,000. A mid-range conservatory with a glass roof costs €15,000 to €25,000. An insulated sunroom with a warm roof costs €18,000 to €35,000. A premium orangery (brick pillars, lantern roof, high-spec glazing) costs €30,000 to €55,000. These prices typically include the frame, roof, glazing, and installation, but may exclude the foundation, electrics, heating, and flooring.
A traditional conservatory has a glass or polycarbonate roof and predominantly glass walls. It suffers from overheating in summer, cold in winter, and noise in rain. A sunroom (or garden room) has a solid insulated roof with glass walls on three sides. It is comfortable year-round, quiet, and energy-efficient. Modern insulated sunrooms are far more popular in Ireland because they can be used as genuine living space every day of the year.
A conservatory or sunroom to the rear of a house, not exceeding 40 sq m, is usually exempt from planning permission under exempted development rules. Conditions apply: it must not reduce the rear garden below 25 sq m, exceed certain height limits, or cause the total extensions to exceed the original floor area by more than a specified amount. Side conservatories, front-facing structures, and those on protected structures or in conservation areas may require planning.
Traditional conservatories with polycarbonate or glass roofs are notoriously cold in winter and expensive to heat. Insulated sunrooms with warm roofs (U-value below 0.18) are a different matter: they retain heat effectively and can be heated comfortably with a single radiator or underfloor heating. If you want a room you can use from November to March, an insulated warm roof is essential.
A well-built, insulated sunroom adds value because it creates additional usable living space. Estate agents estimate that a quality sunroom adds 5-10% to a property's value. A cheap, poorly insulated conservatory that is too hot in summer and too cold in winter can actually detract from value, as buyers see it as a maintenance liability. Quality of construction and year-round usability are the key factors.
Foundation preparation takes 3 to 5 days plus curing time (1 to 2 weeks). Frame and roof installation takes 3 to 5 days. Glazing and weatherproofing take 1 to 2 days. Internal finishes (electrics, heating, flooring, plastering) take another 3 to 5 days. In total, expect 4 to 6 weeks from foundation to completion. If planning permission is needed, add 8 to 12 weeks.
