Outside In
There's a moment in every flat roof extension when a roof lantern changes everything. Natural light pours in from above, the ceiling appears to lift, and a room that felt enclosed suddenly feels open, airy and alive.
At James Alexander, we design and manufacture our roof lanterns in-house at our Milton Keynes workshop by skilled craftsmen, using the latest technology, and built to a standard that off-the-shelf alternatives simply can't match.
Every roof lantern we make is built to measure, designed to fit your extension perfectly and engineered to perform beautifully for decades to come.

HONEST FEEDBACK
Client Reviews
Our hardwood roof lanterns are designed to bring together timeless craftsmanship, elegant detailing and beautifully balanced natural light. Below, we answer some of the most common questions homeowners ask when considering a bespoke hardwood roof lantern.
-
The cost of a hardwood roof lantern will depend on the size, design, glazing specification, finish and the complexity of the installation. Because roof lanterns are often tailored to the proportions of the room and the roof structure below, the final cost can vary considerably from one project to the next.
-
In many cases, no. Planning Portal says new roof lights or skylights will not normally require planning permission provided they meet certain conditions, and current UK roof-lantern guidance also generally treats them as permitted development in most standard situations. Listed buildings, conservation controls and certain site-specific restrictions can change that position, so it is always worth checking before work begins
-
In many cases, yes. Planning Portal notes that installing a rooflight generally involves altering the roof structure, ensuring the roof can carry the load, meeting insulation requirements and considering issues such as fire performance and ventilation. That makes building regulations an important part of most roof-lantern projects.
-
The right size will depend on the dimensions of the room, the size of the roof opening, the amount of light you want to introduce and the proportions of the space as a whole. Current rooflight guidance commonly recommends planning the lantern around the room layout and measuring the opening carefully, with kerb or upstand details also playing an important part in the final specification.
-
Yes, some roof lanterns can be designed with opening sections to provide ventilation, while others are fixed. Ventilation is one of the key factors in helping manage condensation, and both manufacturer guidance and maintenance guidance highlight the importance of airflow in rooms served by roof lanterns.
-
A hardwood roof lantern will benefit from sensible ongoing care to keep it looking its best over time. Current maintenance guidance commonly recommends routine checks, cleaning and periodic upkeep of the finish, with well-maintained timber lanterns expected to last for many years
