If you own a period property in Wiltshire, Oxfordshire, Gloucestershire, or anywhere across the South West, you already know it’s a labour of love. You get the high ceilings, the charming quirks, and the stunning architectural details that modern builds simply can’t replicate.

But when winter rolls in, you also get the downsides. Original timber windows are notoriously draughty. They rattle in the wind, let precious heat escape, and the endless cycle of sanding, priming, and repainting them is a massive drain on your time and wallet. If you’ve ever had to hire scaffolding just to paint your first-floor windows, you’ll know exactly what we mean.

When it comes to replacing them, you’re faced with a tough choice. You want the A+ energy efficiency, security, and zero-maintenance of modern uPVC, but standard shiny plastic frames look completely out of place on a Victorian terrace, an Edwardian semi, or a honey-coloured Cotswold stone cottage. Put the wrong windows in, and you instantly strip the house of its character.

This is exactly why the Residence Collection was created, and why it has become the go-to choice for character homes across our region.

The ‘Fake Wood’ Giveaway: It’s All About the Joints

If you spend any time browsing home renovation forums or chatting with neighbours doing up their homes, you’ll know people are rightfully sceptical about “wood-effect” uPVC. Usually, you can spot it from a mile away.

The dead giveaway? The corners.

Standard uPVC windows are manufactured with a 45-degree diagonal mitre weld where the plastic is melted together. Real timber windows, however, were made by master craftsmen using mechanical butt joints, straight vertical and horizontal lines joined squarely together.

This is where the Residence Collection completely changes the game. Systems like their flagship Residence 9 (R9) are manufactured using advanced techniques that flawlessly replicate traditional mechanical butt joints. When passers-by look at your home, they see the authentic flush sash design and the correct square joinery. It looks exactly like painted wood. In fact, homeowners frequently tell us that it passes the “knock test”, meaning visitors genuinely have to walk up and tap the frame to realise it isn’t painted timber.

Approved for Heritage: What About Conservation Areas and Article 4?

One of the biggest hurdles when upgrading a character property is local planning authority approval—particularly if your home sits within a Conservation Area or is subject to an Article 4 Direction.

Historically, planning officers would insist on like-for-like timber replacements. However, the Residence Collection—and specifically Residence 9, was purposefully designed to satisfy strict heritage guidelines. With its authentic 100mm frame depth replicating 19th-century timber window dimensions, precise sightlines, a chamfered exterior that replicates traditional putty lines, and advanced glass bonding for structural strength, R9 is regularly accepted by local authorities across the South West for heritage and conservation projects.

Planning rules vary by local council, so our team at Emerald Windows can help evaluate your property’s specific planning restrictions and advise on the right specification for your application.

Which System is Right for My Home: R9 vs R7?

If you’re researching the Residence Collection, you’ll likely see both R9 and R7 mentioned. While they share the same stunning timber-effect finish, they suit slightly different property types:

  • Residence 9 (R9): Features a traditional 100mm frame depth. This directly mimics historic 19th-century flush timber windows, offering a flush exterior alongside highly decorative, classic detailing on the inside. It is the go-to choice for strict heritage properties, Georgian, Victorian, or Edwardian homes, and conservation areas.
  • Residence 7 (R7): Features a versatile 75mm frame depth, meaning it is perfectly flush on both the inside and outside. Because 75mm replaces standard modern window depths without needing major plasterline adjustments, it’s ideal for 1920s/30s character homes, barn conversions, or traditional-style self-builds.

The Fitter Matters Just as Much

We want to be totally transparent with you. If you dig into the reviews of premium timber-alternative windows online, you will see a recurring theme from tradespeople and homeowners alike.

For example, in a recent discussion on the r/DIYUK subreddit regarding window quality, one industry expert chimed in to say: “The Residence Collection are very good but you have to have the right property for the Residence R9 – I’ve seen some awful applications of this lovely system!”

That user hit the nail on the head. Residence windows are heavy, highly engineered systems—especially when holding thick, acoustic triple glazing. They are not standard off-the-shelf windows, and they require a specialist touch. If a fitter rushes the job, assesses the lintels incorrectly, or fails to properly glass-bond the units, the window simply won’t perform.

When you read advice online about upgrading to premium windows, the most common tip is to avoid the big, faceless national companies and choose a trusted local installer. As a family-run company operating in Swindon and the South West since 2004, Emerald Windows doesn’t do “rush jobs.” We treat your property with respect, take the time to measure precisely, and our fitters have years of specific experience handling the heavy, complex profiles of the Residence Collection.

Real-World Results: A Cotswold Self-Build Case Study

It’s easy for us to talk about how authentic these windows look, but we prefer to show you. We recently worked with Mr & Mrs Rusling on a stunning self-build project in the Cotswolds.

Their goal was to create a traditional farmhouse appearance using natural stone and handcrafted elements. They wanted a home that blended into the rural landscape and felt like it had always been there. Standard shiny windows were out of the question; they needed heritage-style windows that looked entirely authentic.

After being let down by a previous installation company, they turned to Emerald Windows for Residence windows to get the project back on track. They opted for the Residence Collection R7 flush casements. The R7 system provided the external astragal bars and mechanical-style joints that replicate handcrafted joinery, perfectly complementing the traditional Cotswold style they were building. To ensure the frames didn’t look like obvious new-build plastic against the natural stone, they selected a soft Pebble Grey exterior finish with a bright White Grain interior, delivering the modern, draught-free performance they required to meet strict self-build building regulations.

Colours and Hardware That Belong in the Shires

Brilliant white plastic against weathered red brick or natural Cotswold stone can look incredibly jarring. Character homes need softer, more authentic tones.

The Residence Collection comes in an exclusive range of heritage colourways that look like they were pulled straight from a luxury period paint chart, such as Cotswold Biscuit, Clotted Cream, Painswick, and English Oak. They feature a highly realistic woodgrain texture that will never fade, crack, or peel.

You can finish the look with period-accurate hardware. A standard modern window handle on a 19th-century style frame ruins the illusion instantly, so Residence windows can be fitted with authentic working peg stays, and heavy-duty handles in classic Monkey Tail or Pear Drop designs.

Come and See for Yourself

Choosing windows for a character home is a big decision, and you shouldn’t have to make it just by looking at a screen. At Emerald Windows, we never use a hard sales approach—we believe in honest, local advice and letting the quality of the product speak for itself.

You really need to run your hands over the woodgrain texture, feel the weight of the handles, and inspect those authentic mechanical-style joints up close. Just like Mr & Mrs Rusling found during their self-build, seeing the product in person is often the turning point that gives homeowners absolute confidence.

We actively encourage you to visit the Emerald Windows showroom in Swindon. Our friendly team is on hand to talk you through configurations, building regulations, and budgets, so you can walk away feeling entirely relaxed about your home improvement investment.
