WHAT MAKES UP OUR LANTERN ROOF SINGLE STOREY EXTENSIONS

DURABASE SYSTEM

Our extensions are built on top of a durable steel base system with a stylish brick slip border, complete with 100 mm floor insulation and 22 mm chipboard flooring.

160MM WALL STRUCTURE

The base is topped by 6 × 2” structural grade timber wall sections, covered with a 15 mm OSB outer skin.

PREMIUM INSULATION

125 mm multifoil honeycomb insulation is pre-fitted into all wall and roof sections for maximum thermal efficiency.

EXTERNAL CLADDING

The structure is covered with innovative exterior PVC cladding that features an authentic embossed wood-effect finish, complete with all finishing trims.

EPDM ROOF RUBBER

Choose between the classic slate appearance or a more traditional shingle style, both available in various colour options.

OPTIONAL SPOTLIGHTS

Create a striking modern look by adding optional spotlights to your extension's soffit detail.

FLAT & LANTERN ROOF EXTENSION OPTIONS

Our lanterns are placed on top of a flat roof base. If you'd like, we can install the base without adding a lantern. Here are your two options:

LANTERN ROOF

Our lantern roofs feature a flat base topped with a glass structure that rises like a greenhouse. Perfect if you’re looking for a brighter space with more vertical room.

FLAT ROOF

Our flat roofs feature a clean, low-profile design ideal for creating a modern atmosphere. Optional skylights allow for customised light and shade.

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.
