I recently had an Edwardian hipped extension completed by Single Storey Extensions, with Ash tiles, and the outcome was amazing. The level of professionalism demonstrated by their team from the beginning to the end of the project was truly impressive. Their attention to detail and commitment to quality was evident in every aspect of their work. Getting Single Storey Extensions to handle our Edwardian-hipped extension was an excellent choice. I strongly recommend their services to anyone looking to undertake a similar job. Their dedication to delivering top-notch results is genuinely praiseworthy.

LANTERN ROOF EXTENSION FAQS

Our lantern roof extensions are precision-engineered to maximise overhead natural light. The pitched angle of the glass panels is mathematically calculated to capture daylight from all directions and distribute it deep into your floor plan. This architectural light-well effect significantly brightens your home, dramatically reducing the need for artificial lighting during daylight hours.

Yes! Our modular system allows you to tailor your home upgrade to perfectly match your property. While the structural flat roof base handles the overall extension layout, the central lantern glass feature can be customised across a wide range of proportional rectangular dimensions and frame colours to fit your design vision.

We use high-performance, toughened safety glass that features exceptional thermal efficiency and home security. This specialist glazing reflects scorching summer solar heat while trapping interior warmth during the winter, keeping your single storey extension comfortable all year round. The exterior glass also features a low-maintenance coating that breaks down organic dirt using UV rays, making cleanup effortless.

Our lantern extension kits are built to comfortably withstand the harshest British weather conditions. By combining heavy-duty 6x2" structural timber perimeter decks with weather-sealed marine-grade aluminium glass frames, the entire structure easily handles high wind loads and heavy winter snow without any risk of structural deflection or leaking.
