Ultra-slim Sliding Doors for A Modern Extension in Lincolnshire

THE OLD RECTORY, LINCOLNSHIRE

GS20 Sliding Doors Deliver Seamless Garden Connection in a Heritage-Inspired Modern Extension

Set within 8 acres of secluded grounds in the village of South Kelsey, Lincolnshire, The Old Rectory combines heritage architecture with a modern side extension. 

The unique location of this outstanding home needed an extension that drew light in and connected  surrounding countryside to the home. Designed by ID Architecture, the project reworks a series of fragmented and outdated additions like a conservatory, into a more unified structure.  The result is a family home with better flow internally, substantially improved looks externally with security, energy efficient and interior comfort.

Blending Old and New with Light, Materiality and Framing

Originally built in the early 19th century, The Old Rectory had seen a number of alterations that diluted its historic charm. The new extension replaces a large uPVC conservatory with a contemporary all-round usable room, without the too hot in summer, too cold in winter issues that plague plastic conservatories.

The new structure uses timber cladding and exposed glazing to contrast and complement the existing red brick façade of the main house. 

Glideline GS20 Sliding Doors in Lincolnshire

Central to this transformation, Glideline’s GS20 sliding doors were specified for their slim profile, high performance, and ability to deliver an unobtrusive, architectural glazing solution suited to a conservation-sensitive setting.

The architectural intent was to create openness and a connected room to the outside.  All of this is possible with our expertly-manufactured GS20 sliding door, with its desirable 20mm mullion and maximum use of glass.

The doors are intalled at ground level beneath the cantilevered upper floor, allowing the GS20 sliding doors to work with the kitchen and living spaces that both open out to the garden and Lincolnshire countryside.

Why GS20 Was Selected
The success of the project depended on creating a crisp, pared-back aesthetic that wouldn’t visually compete with the heritage elements of the house. The GS20 sliding system we’ve designed over the years with several technical and design advantages:

• Ultra-slim sightlines for expansive, uninterrupted views across the grounds

• Floor-to-ceiling glazing with smooth, flush threshold options and fully weatherproofed

• Structural capacity to support large glass units and minimal visual frame.

• Latest generation thermal insulation, with polyamide thermal breaks.  The high performance glass uses 30mm thick safety glass, having a soft-coat low-emissivity coating, warm edge spacer bars and argon gas fill. 

Enhancing Liveability Through Architectural Glazing

Internally, the GS20 system improves daylight access into open-plan living spaces, including the once-underused lower sitting room. With its new patio access, improved insulation, and visual openness, the room now functions as a warmer, better insulated rooms. Whether our slimline sliding doors are open or closed, there is always a connection with the outdoors.

Glideline manufactured the doors to order at full span, ensuring precise alignment with structural elements and floor finishes. The result is a clean, low-maintenance system that offers smooth daily operation and long-term reliability—ideal for a family home designed to evolve with its occupants.
