We love our Bristol terraces for their soul, but not for their draughts. Here’s how we’re bringing 19th-century charm into the 2026 energy landscape.
Respecting the Old, Powering the New: The Art of the Bristol Retrofit
By Wagner, Head of Door 5 Studio
If you live in Bristol, you know the charm of a Victorian terrace. Those high ceilings, the intricate cornicing, the bay windows that watch over our hilly streets—they have a soul that modern "boxes" just can’t replicate.
But let’s be honest: they can also be cold, draughty, and shockingly expensive to heat.
In my work at Door 5, I often see homeowners caught between two loves: their love for heritage and their desire for a sustainable, modern life. The good news? You don't have to choose. In 2026, we have the tools to turn these 100-year-old beauties into high-performance homes without losing an ounce of their character. Here is how we approach what I call "The Empathetic Retrofit."
1. The "Fabric First" Philosophy Before we talk about heat pumps or solar panels, we talk about the "envelope" of your home. Victorian houses were designed to "breathe," which is great for avoiding damp, but terrible for keeping heat in.
We look at "breathable" insulation—materials like wood fibre or hemp-lime—that respect the original solid-wall construction. It’s about making the house airtight enough to be warm, but "smart" enough to manage moisture.
Local Insight: The Centre for Sustainable Energy (CSE), right here in Bristol, is a fantastic resource for understanding the "Retrofit Pattern Book" specific to our city's housing. Explore their Bristol-specific retrofit guides here.
2. Windows: Secondary Glazing vs. Restoration The original timber sash window is a piece of art. Ripping them out for standard uPVC is, in my view, a tragedy for the streetscape. Instead, we often specify high-performance slimline double glazing that fits into original frames, or sophisticated secondary glazing that is almost invisible. It keeps the "Bristol look" while silencing the street noise and the winter chill.

3. From Gas to Grace: The Energy Transition The 2026 energy landscape is shifting fast. With the UK's move toward "Future Homes Standards," we are helping more clients transition from gas boilers to Air Source Heat Pumps.
The secret to a successful heat pump in a Victorian home isn't the machine itself—it's the system design. It’s about larger, elegant radiators or underfloor heating hidden beneath reclaimed floorboards. It’s technology that works quietly in the background, so you can focus on the living.

The Door 5 Approach Retrofitting a period property is like a conversation between the past and the future. It requires a gentle hand and a technical mind. Whether you are in a Clifton villa or a Bedminster terrace, your home has the potential to be a beacon of sustainability.
