A fine example of modern styling
The flat roof system we supply at TradeMark will give your extension the utmost strength and simplicity. Consider adding bi-folding doors or large sliding doors to the design to establish a light and spacious feel. An overhang on the outside will also provide you with an undercover seating area.
The presence of insulating technology within the flat roof extension will keep it well insulated, leaving you with a living space that feels lovely and warm on every occasion that it gets used.

Customised for you
No-one will have a roof quite like yours as it will be specially tailored to ensure that its shape and finish complements your home. If you wish, it’s possible to include bi-folds that span up to 5.8m without the need for additional pillars, giving you a near predominantly glazed extension.

Add some light
Planning an extension is all about the detail and marrying everything together in a single design. Amongst the add-ons you can have include lanterns, skylights and many different soffit and fascia options, allowing you to fully personalise it.

Flat Roof features
The addition of a flat roof extension will get people talking, especially if it has cutely executed asymmetrical angles and edges. What will give it a dramatic finish is the inclusion of lanterns and flat skylights.

Expertly Pitched
Natural light will flood the inside of your orangery when you have an expertly pitched lantern sitting on top of the design, leaving it bright and airy. There are many thermal components in the lantern which each help to keep the space energy efficient.

Frameless Skylights
You get edge-to-edge glazing with a frameless skylight, a feature that will be a centrepiece of the design and one that gives the sun a direct passage into the heart of it. It has an unbelievably slim aluminium surround and fully insulated housing section that benefits from Warm Frame technology, with noise reducing glass provided as standard.
