Glass Sliding Doors in Wales for a Contemporary Coastal Home

The minimal windows® glazing strategy is focused on the first floor living spaces, where large sliding glass doors frame the coastal landscape and provide access onto a balcony that wraps around the home.

The largest installation extends approximately 9.6 metres across the principal elevation and comprises four panels, with two fixed panes and two sliding panes. An adjoining side return, measuring approximately 4.8 metres wide, incorporates one fixed and one sliding panel to form an opening corner.

A further two panel sliding system was installed within the first floor master bedroom. This comprises one fixed and one sliding pane, with an internal frameless glass Juliet balcony positioned across the opening for safety while preserving clear outward views.

Together, these systems create expansive glass walls across the upper floor, reinforcing the connection between the interior architecture and the Gower coastline.

The design of Silver House responds to the material character and exposed conditions of its coastal setting. The ground floor references the local tradition of dry stone walling, while the upper living spaces rest on exposed timber beams informed by the construction of nearby agricultural buildings

The principal living accommodation was positioned at first floor level to take advantage of the views. Large areas of sliding glass were essential to this arrangement, allowing the interior spaces to open onto the balcony while keeping the aluminium framing visually recessive.

The opening corner further reduces the visual and physical division between the living space and balcony. When the doors are open, the solid corner is removed, creating a broad connection with the coastal surroundings. When closed, the large glass panes and slim profiles maintain panoramic views from inside the home.

For architects, developers and private clients considering glass sliding doors in Wales, Silver House demonstrates how minimal framed systems can become an integral part of a coastal architectural concept rather than simply providing access.

The principal minimal windows® installation combines two coordinated sliding systems to form the opening corner. Across the main elevation, the system measures approximately 9649mm wide by 2335mm high and comprises two fixed and two sliding panels.

The side return extends approximately 4882mm and incorporates one fixed and one sliding panel. Together, these elevations create a large corner arrangement that opens the first floor living area onto the wraparound balcony.

Within the master bedroom, a further sliding system measures approximately 5076mm wide by 2588mm high. This two track configuration contains one fixed and one sliding panel, with the frame positioned below the internal floor level to support a minimal junction at the base of the glass.

Slim 21mm interlockers reduce the visible aluminium where adjacent panes meet. This allows the large glass walls to retain a refined appearance while preserving uninterrupted views towards the coast.

The sliding door systems use double glazed clear toughened safety glass. Solar control glass was specified to the balcony sliding system to help manage solar gain across the extensively glazed first floor living spaces.

The master bedroom system incorporates double glazing with a Low-E coating, supporting thermal performance while maintaining glass clarity and outward views.

All minimal windows® frames are finished in RAL 9005 matt black. The dark finish coordinates with the wider material palette and allows the slim profiles to recede visually against the glass. Flush threshold detailing maintains clean transitions at the openings, while multi-point slim Type 1 shoot bolt locking systems provide secure operation.

Silver House demonstrates how glass sliding doors in Wales can define a contemporary coastal home by framing panoramic views, increasing natural light and creating a closer relationship between the living spaces and surrounding landscape.

The opening corner allows the principal first floor living area to extend onto the balcony, while the large format glass maintains visual contact with Oxwich Point when the doors are closed. In the master bedroom, the additional sliding system and internal Juliet balcony provide ventilation and openness while preserving safety and clear coastal views.

For architects, developers and private clients seeking premium sliding glazing for a coastal new build, Silver House provides a clear example of how minimal windows® systems can combine opening corner configurations, slim sightlines and project specific glass specifications within a carefully resolved architectural design.
