Conservatory or extension
Conservatory vs extension — an honest Kent comparison
Conservatories are cheaper up front. Proper extensions cost more and usually live better year-round. If you are weighing both in Medway, here is how we explain the trade-offs.
How they feel to live in
A typical older conservatory overheats in summer and chills in winter. Newer orangery-style builds with insulated roofs are better, but a masonry or timber-frame extension with a solid roof still wins for year-round kitchen-diner use.
If the room will be your main family space, build it like part of the house. If you want a sun room for weekends, a quality glazed structure can be enough.
Cost, planning and structure
Conservatories often look cheaper on paper. Foundations, electrics and opening up to the house still add up. Replacing a failed conservatory with an extension later means paying twice.
Extensions need building regulations as standard. Some conservatories historically sat in grey areas — do not rely on that for a main living room in 2026.

- Build cost vs lifespan
- Opening width into the house
- Future saleability
Replacing an existing conservatory
We are often asked to take down a tired conservatory and put a proper extension on the same footprint. Base conditions vary — some slabs are fine, some need redoing.
Napwood will survey what you have and say whether you can reuse any of it or whether a clean rebuild is the sensible path.
FAQs
Frequently asked questions
Is an extension always better than a conservatory?
For a main kitchen-diner, usually yes. For occasional garden-room use, a well-specified glazed structure can be proportionate.
Can you build on my old conservatory base?
Sometimes. We check levels, reinforcement and damp. Guessing leads to cracking and cold floors.
Will removing a conservatory need planning?
Replacing with a similar or compliant extension may have different rules to the original. We review planning and building control together.
