☉ At RISE Design Studio, we believe good architecture doesn’t just shelter us - it sustains us. That means thinking beyond cold snaps and insulation R-values. As our summers get longer, hotter, and more unpredictable, the conversation around retrofit must evolve. It’s no longer just about warmth - it’s about resilience.
Ongoing retrofit work at our Herbert Paradise project featuring high-performance insulation and MVHR system for a whole-house ventilation system - part of a climate-resilient design strategy to prevent overheating in summer and ensure year-round comfort.
For too long, retrofit has been cast as the hero of the winter story - thicker walls, better boilers, lower bills. But buildings don’t hibernate. They breathe, live, expand, and contract. And as the mercury climbs each year, homes across the UK - especially those built in a time when coal was king and climate change wasn’t on the radar - are being pushed beyond their limits.
Overheating is no longer an edge-case. It’s becoming the norm. And retrofit is one of the few tools we have that can protect our homes - and the people inside them.
Cool homes start with clever thinking. Retrofit gives us the chance to correct the blind spots of the past:
External insulation that doesn’t just keep the heat in but keeps unwanted solar gain out
Windows that work with the sun, not against it
Shading and brise-soleils that are as beautiful as they are functional
When we treat every retrofit as a moment to reimagine the building envelope, we can design homes that inhale summer - rather than suffocate in it.
☉ Airtight buildings are great for energy. But without ventilation, they become boxes of stale, humid air.
Whether it’s a cross-breeze through sash windows or a whole-house MVHR system, fresh air is fundamental. In summer, it’s not a luxury - it’s a safeguard. Especially for those most vulnerable: the elderly, children, and people with health conditions.
We’ve seen it firsthand: when ventilation is planned in harmony with insulation and airtightness, the result is more than thermal comfort. It’s peace of mind.
Sensor-driven systems can now track temperature, humidity, and air quality in real time. But tech alone isn’t the solution. Retrofit is not a plug-and-play process.
We’ve learned that lasting change comes when residents feel empowered. That means:
→ Simple interfaces
→ Thoughtful onboarding
→ Designing with people, not just for them
When residents understand the system, they use it. When they use it, it works. And when it works, homes stay comfortable without compromising sustainability.
Too hot or too cold - either extreme strains the body. Overheating has been linked to stress, fatigue, poor sleep, and even respiratory issues.
But when a home is just right, the effects ripple outward:
Children concentrate better
Elders sleep deeper
Everyone feels more rooted
Retrofit is public health in built form. And when done well, it lifts communities. It reduces the burden on services. It fosters pride. It creates spaces that hold people with care.
☉ One of the biggest lessons from two decades of retrofitting: if you treat a home like a checklist, it behaves like one. But treat it as a living organism, and something changes.
Insulate a roof without thinking about ventilation and you might trap heat. Seal up windows without adding shading and you might bake the rooms. It’s all connected.
Every retrofit should begin with a deep, holistic understanding of the building and end with one simple question: will this make someone’s life better through every season?
The UK’s decarbonisation drive is necessary. But the goal can’t just be hitting carbon targets. The goal has to be homes that feel good to live in. Every day. In any weather.
We see retrofit not as repair, but as reinvention. And we urge housing providers, contractors, and architects alike to plan for heat as much as they plan for cold.
Because when we design for both, we don’t just create energy-efficient homes. We create homes that support life.
Retrofit is not simply a technical intervention. It’s a social one. A sustainable one. A deeply human one.
This is about creating homes that feel calm in the chaos. That let children play on the floor without overheating. That allow people to rest, think, breathe, grow. It’s about homes with dignity.
And it all starts with design that looks beyond the next season and reaches for the next generation.
→ That’s what we do at RISE.
At RISE, retrofit isn’t just about fixing the past - it’s about future-proofing the present. It’s how we transform everyday homes into sanctuaries that breathe, adapt, and endure. Homes that stay cool when summers swell. That use less, but give more. That protect the people inside while treading lightly on the planet.
Considering a retrofit or deep energy upgrade?
Let’s create a home that’s ready for tomorrow – and rooted in purpose.
