How we approach glass links & glass box roofs in Hounslow
Our glass links & glass box roofs service in Hounslow covers frameless glass links joining old and new buildings. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. In Hounslow, as anywhere, glass links & glass box roofs are the usual choice for joining a period house to a new extension or annexe.
From Hounslow to Isleworth, Twickenham and Richmond, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning, building control and Hounslow
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
Read the planning permission guide before you commit to a design.
