When you’re building your forever home, every detail matters. Especially when you’ve invested years planning something so personal. For Mr and Mrs Rusling, self-building a house in the Cotswolds, the goal was more than simply choosing new windows; it was about helping a new house look and feel like it had always belonged in the rural landscape around it.  

They wanted a traditional farmhouse appearance inspired by classic Cotswold architecture, using natural stone, handcrafted elements and heritage-style windows that looked authentic rather than modern or plastic. Flush casement styling and a timber-look finish were essential from the very beginning.  

However, their journey wasn’t straightforward. After being let down early in the build by another double-glazing company and losing confidence in the process, they were eager to find a company that could help them regain control of the project and bring their original vision to life.  

Choosing Traditional Windows for Self-Build Homes

The homeowners already lived locally and wanted to raise their family in the countryside. When a plot became available with open field views, they decided to replace the existing house with a self-build designed around traditional Cotswold farmhouses.  

Their brief focused on natural materials such as stone and cast iron, heritage-inspired detailing and windows that looked like timber without the ongoing maintenance. More than anything, they wanted a home that blended into the landscape and felt like it had always been there.  

Flush casement windows were essential. The Rusling’s loved the handcrafted appearance of timber but needed modern efficiency and low maintenance to suit family life.  

 Challenges When Choosing Replacement Windows

Before finding Emerald Windows & Doors, the couple worked with another company whose installation didn’t go as promised. This left them feeling disappointed and unsure of whom to trust moving forward. The setback delayed their build and made them particularly cautious about their next steps.  

 

Finding a Reliable Window Installer in Swindon

Determined to move forward, the couple began researching alternatives and already knew of the Residence Collection. They had always admired the R7 system for its traditional look and modern performance.  

When Mr & Mrs Rusling visited our Swindon showroom and saw the Residence Collection R7 flush casement in a finish close to what they originally imagined, it was a turning point. They finally felt confident that their original vision could still be achieved.  

Their priority was to restore the plan they started with, ensure the installation was handled carefully and have clear communication throughout so the couple always felt supported.  

 

Heritage Windows Specification and Colour Options

After discussions with a member of our sales team in our showroom and at the property, the final specification for the sixteen windows includes:  

  • Residence Collection R7 flush casement windows  
  • Pebble Grey external finish  
  • White Grain internal finish  
  • External astragal bars  
  • Mechanical-look joints  

 

Residence Collection R7 Windows vs Traditional Timber Windows

Residence Collection R7 offered an authentic, timber-like appearance to complement the traditional farmhouse style, with flush casements designed specifically for heritage settings. The system provided external astragal bars and mechanical-style joints that replicate handcrafted joinery while still meeting modern energy performance, security standards and building regulations.  

 Choosing the Right Colour for Cotswold Stone Properties

Colour was one of the most carefully considered elements of the project, driven by a clear desire to preserve the character of the home.  

As Mr and Mrs Rusling explained: “We wanted to avoid it looking like a new build with obvious plastic windows. The idea was that you shouldn’t quite be able to tell how old the house is.”  

To achieve this, the homeowners studied older Cotswold properties to identify the tones traditionally used. Pebble Grey emerged as a soft, sympathetic choice that complements Cotswold stone detailing without introducing a modern edge. Inside, White Grain keeps rooms bright while retaining a subtle heritage texture.  

Installing Windows in ICF and Stone Self-Build Structures

This wasn’t a straightforward installation. The house combines an ICF (Insulated Concrete Form) core, stone cladding on the front elevation, render on the rear and splayed internal reveals designed to increase natural light.  

This mix required careful planning around fixing positions, airtightness and structural considerations. Our approach included digital surveying, a detailed review of build layers before installation, and ensuring all openings were prepared correctly for the diverse substrates.  

 Expert Heritage Window Installation

One of our lead installers approached the project with the same mindset as the homeowners - do it properly and get the details right.  

He recommended a more traditional cill return on the rear elevation to reflect older stone designs and created a colour-matched perimeter finish around the frames to soften the junction with the stonework. This small detail helped remove the typical “uPVC edge” and made the frames appear more like timber.  

Different fixing methods were used depending on the build-up behind each opening, rather than relying on a single approach. Astragal bars were carefully aligned to form symmetrical sightlines and a traditional grid layout, helping the windows appear handcrafted rather than manufactured.  

 The Result

Once installation was complete, the couple described feeling relieved and pleased with the outcome. The home is noticeably quieter and warmer, the windows now look as though they have always belonged there, and the colours complement both the stonework and cast-iron detailing.  

Most importantly, the couple feel their trust has been restored. What began as a stressful setback became one of the most satisfying achievements of their self-build journey.  

 Advice for Other Self-Builders

The homeowners recommend researching real homes rather than relying solely on brochures, talking to companies with experience in heritage-style installations and making sure you’re working with a team that understands both the product and the type of build involved.  

The couple would happily recommend Emerald Windows & Doors to other self-builders and homeowners looking for a heritage-style installation handled with care. 

Their experience highlights the importance of researching installers carefully, reviewing real project work, and choosing a company with proven experience.
