Glass links & glass box roofs for Havant: the essentials
Glass links & glass box roofs in Havant means frameless glass links joining old and new buildings. We cover the PO9 district and the rest of Hampshire, with a survey before any price is fixed.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. In Havant, as anywhere, glass links & glass box roofs are the usual choice for listed and period buildings where the old wall should stay visible.
From Havant to Waterlooville, Portsmouth and Gosport, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning, building control and Havant
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
