The Dunvegan Two

All the sophistication of the Dunvegan Door, but with an added glass panel and off-centre styled finish to maximise natural light in entranceways.

Dynamic design, reimagined.

The Dunvegan One

The stripped back, modest appeal of the Dunvegan makes it one of our most popular choices. Simple enough to suit a more traditionally styled home, yet perfectly in-keeping with bolder 21st century style choices. The single centrally-placed glazing approach gives this door a powerfully bold appearance.

Supremely powerful design.

Keeping your home safe

Whilst we understand it’s important your door looks great, we know that the safety of you and your family always comes first. We’ve put safety at the forefront of the entire creative process when it comes to the Extreme Solid Core Door, motivated by a recent statistic which revealed that an alarming 35% of break-ins in the UK occur through the front door. With this firmly in mind, we adopted a policy that allowed us to create a product that was the pinnacle of modern safety. This is exactly why we’ve included only the strongest locks and hardware on the entire range.

‘Secured by Design’

The next step on our journey was to have the Extreme Solid Core Door attain the coveted ‘Secured by Design’ seal of approval. To add some context to this, ‘Secured by Design’ is a police-led initiative that’s been designed to combine the concept of ‘designing out crime’ with physical security. Following an extensive testing process, we couldn’t be happier with the outcome, as every door in our range has passed with flying colours. Speak to a member of our team about the options you can choose to ensure your door remains ‘Secured by Design’.

Energy Savings

Save money, keep warm.

Keep the warmth in, keep the cold out. It’s that simple. This has been our mission statement with the Extreme Solid Core Door from the very beginning. With its robust 48mm Extreme Solid Core, packed full of 16 robust layers of timber, we’re confident in saying that we’ve achieved our goal. Put your feet up on even the coldest of winters nights knowing that your Extreme Solid Core door will keep you warm! We’ve then added an additional three weather seals for extra protection against the cold, and extra protection for your bank account against excessive heating bills.

Customise until complete

Classic Hardware

We’ve made sure that the classic hardware range that accompanies the Extreme Solid Core Door range has been created with the scope to match every home. With this in mind, you have the freedom to complete the look by matching one of our sophisticated handles with an urn-style door knocker and accompanying letterplate… If that’s your thing, that is.

Slam-Shut Hardware

Set aside from competitors, the Solid Core range contains brushed silver slam-shut hardware designed to continue the theme of security and style as one. Bar and Bow handle configurations can be applied to provide a contemporary feel, whilst those of you seeking a more traditional look may want to opt for a cottage-style cylinder pull. One thing that is for sure is that both options will provide excellent security year-round.

Let your style run free
