Traditional Strength Meets Modern Precision: JMK Oak Frame Extensions & Buildings in Leicestershire and the Midlands

At JMK Roofing, we pride ourselves on crafting oak frame extensions and oak buildings that blend traditional craftsmanship with modern performance. Based in Leicestershire, we serve homeowners across the Midlands with beautifully built, long-lasting oak structures that stand the test of time—both structurally and aesthetically.

Built to Last: Traditional Joinery That Strengthens Over Time

What makes our oak frame buildings truly exceptional is our use of traditional joinery techniques that have been trusted for centuries.

• Dovetail joints and jowl posts form the backbone of our frames. These age-old methods create incredibly strong connections that resist lateral movement and distribute weight evenly, giving your oak extension a rock-solid foundation.

• We use seasoned oak pegs to secure joints. As the oak naturally dries and seasons over time, these pegs tighten and strengthen the connections rather than weaken—something screws and bolts simply can’t match.

This commitment to time-honoured techniques ensures that every JMK structure gains character and strength as it ages.

Modern Detailing for Long-Term Performance

While our craftsmanship is rooted in tradition, we integrate smart modern construction methods to improve the overall performance of our oak buildings.

One of our key innovations is the way we encapsulate glass panels within the oak frame. Oak is a living material that continues to move slightly as it seasons. Our glass detailing system allows the oak frame to move without breaking the seal—ensuring long-term water tightness and energy efficiency.

This hybrid approach—respecting tradition while embracing innovation—sets JMK apart as a trusted builder of high-quality oak frame extensions in Leicestershire and across the Midlands.
