For anyone planning work to the ground floor of an older house, this event may be of interest.

This Monday at 19:30, we’re hosting the Floors session of The Breathable Home Series, a free live online workshop focused on how traditional floors in stone and masonry buildings were designed to function, and what can go wrong when modern systems are introduced without understanding that.

If you’re already booked in, this is just a reminder that the session takes place on Monday evening.

If you’ve been considering it but haven’t registered yet, there’s still a short window to do so. We’ll be closing bookings soon so that the session remains practical and interactive.

We’ll be covering why older floors were built the way they were, how moisture moves through the ground and into walls, and why concrete slabs and plastic membranes can sometimes create unintended damp issues.

We’ll also explain how breathable alternatives such as limecrete and foamed glass insulation work, how the layers interact, what finishes are compatible, and how to phase works if you’re living in the house at the same time.

It’s intended for homeowners, self-builders and tradespeople who want to understand the principles before making decisions, particularly where damp or floor replacement is involved.
The session runs for approximately 90 minutes and includes time for open questions.

If you’re weighing up options for a floor upgrade, this should give you a clearer framework for thinking it through.

If you’re thinking about insulating your attic or carrying out roof works on an older property, this may be relevant to you.

On Monday August 24th, we’re hosting the Roofs & Attics session of The Breathable Home Series, a free live online workshop focused specifically on upgrading traditional roofs without creating condensation or moisture problems.

For those already signed up, this is a gentle reminder that the session takes place on Monday evening.

For anyone who has been considering it but hasn’t registered yet, there is still time.

Roofs in older stone and masonry homes were built to breathe and shed moisture in a particular way. When modern membranes, insulation systems or vapour barriers are introduced without understanding that balance, issues such as mould, trapped condensation and timber decay can follow.

During the session, we’ll look at how traditional roofs function, when a warm or cold roof approach is appropriate, how breathable underlays differ from non-breathable ones, and how natural insulation materials such as woodfibre can be incorporated safely.

It’s intended for homeowners, self-builders and tradespeople who want clarity before making decisions, especially if roof replacement or insulation upgrades are being planned.

The workshop runs for approximately 90 minutes and includes time for questions at the end.

If roof work is on your list this year, this session should give you a clearer understanding of how to approach it in a way that respects the building.

A quick reminder for anyone renovating, repairing or living in an older stone or masonry house.

Next Monday, we’re running the Walls session of The Breathable Home Series, a free, live online workshop focused on how traditional walls actually work, and why so many modern “solutions” end up making damp problems worse.

If you’ve already signed up, this is just a reminder that the session is coming up on Monday evening.

If you haven’t, there’s still time to join - but booking will close shortly so we can keep the session manageable.

The workshop looks at how stone and brick walls deal with moisture, why cement renders, tanking slurries, rigid insulation boards and plastic membranes often cause long-term issues, and what breathable alternatives make sense in older buildings.

It’s aimed at homeowners, self-builders and tradespeople, architects who want to understand the reasoning behind the advice, not just be told what to do.

The session is live, runs for about 90 minutes, and includes time for questions at the end.

If you’re dealing with damp walls, cold rooms, or conflicting renovation advice, it may help to hear how these buildings were originally designed to function before making your next decision.

Following the fantastic response to our first FREE 3-part Breathable Home Series, we're delighted to be running it again.

The level of interest, the questions asked and the feedback we received showed us just how many homeowners, self-builders and tradespeople are looking for clear, practical advice on renovating traditional buildings.

If you're working on an older stone or masonry house, you'll know that modern renovation advice can often be confusing. Many of today's standard building methods simply weren't designed for solid-walled buildings, and well-intentioned upgrades can sometimes create damp, condensation and long-term moisture issues.

That's why we're once again hosting this free online educational series, designed to explain how traditional buildings actually work and how to improve their comfort and energy performance without compromising their ability to manage moisture.

Walls – Monday 10th August | 19:30
Understand how traditional walls manage moisture, why cement and impermeable systems can create problems, and how breathable insulation and lime-based finishes really work.

Roofs & Attics – Monday 24th August | 19:30
Learn how to insulate roofs safely while avoiding condensation and protecting the building fabric.

Floors – Monday 7th September | 19:30
Explore how traditional floors manage moisture, why concrete slabs can create problems, and how breathable systems such as limecrete and foamed glass behave differently.

Each session is live, runs for approximately 90 minutes, and includes plenty of time for questions.

A remarkable restoration at Carrickfergus Congregational Church.

The interior was fully replastered using a traditional three-coat lime system with a lime putty finish, alongside extensive in-situ moulding work including arches, architraves, pilasters, fluted columns and circular window details.

A great example of the versatility and beauty of traditional lime plastering.
