Conservatories vs Lantern Roofs: Which Extension Is Right for Your Home?

Updated: Sep 2




Two of the most popular glazing extensions for Essex and North London properties are conservatories and roof lanterns. Both flood your home with natural light, but they suit different property types and budgets. Here's how to decide which is right for you.

A conservatory is a standalone extension — typically built on a brick or block base with glazed walls and a glazed or insulated roof. It adds a completely new room to your home. Popular styles include Victorian (with bay front), Edwardian (rectangular, maximises floor space), lean-to, and the orangery-style that combines solid walls with a central lantern.

A lantern roof is a raised glazed element that sits on top of a flat roof — typically over a kitchen extension or single-storey rear extension. It doesn't add floor space but dramatically changes how an existing flat-roof room feels, flooding it with light from above.

Conservatories are ideal for: Loughton, Mill Hill, Whetstone and similar suburban areas where plot size allows a side or rear extension; homeowners who want a dedicated garden room, dining space or home office; properties with south or west-facing rear aspects.

Lantern roofs are ideal for: Victoria Park (E9), Hadley Wood (EN4), Highgate (N6) and areas where kitchen-rear extensions are already in place; flat-roof kitchens that feel dark and cave-like; homeowners who want maximum impact with minimal planning risk.

Warning signs and safety advice


Arrange a professional inspection if you notice any of the following:

  • Glass or polycarbonate panels visibly slipping from the ridge or showing gaps.

  • Loose cappings, ridge covers, end caps or glazing bars.

  • Leaks, damp marks, draughts or movement during windy weather.


If any glass, roof panel or external component appears loose or displaced, keep people away from the area beneath it and do not attempt to force it back into position. Seek professional advice promptly.
