Configurations
This Muswell Hill home was transformed with a rear extension and loft conversion, featuring Keller minimal windows sliding doors throughout. At ground floor level, a corner-opening pocket door system allows the entire corner of the living space to open, creating a seamless connection to the garden.
The minimalist glazing design combines ultra-slim sightlines with concealed pocketing, enabling all sliding panels to disappear into hidden wall cavities when open. The result is an unobstructed opening that maximises light, views and indoor-outdoor living.
Set within a traditional North London brick façade, the dark grey aluminium frames were detailed flush with the external brickwork to create a clean, contemporary appearance while complementing the character of the existing home.

When closed the corner pocket doors offer the slim vertical sight lines of minimal windows with floor to ceiling glass. This allowed the interior living spaces and new kitchen to connect directly to the garden both visually and practically.
When open all three sliding glass panes slide away from the 90 degree corner connection into hidden pockets creating a fully open aperture and connexion to the outdoors.
These same slim sliding glass doors were used on the upper floor to the new master bedroom set within the loft. To create a cohesive design the same RAL colour was used to the loft bedroom sliding doors. The glass sliding doors to the loft were designed in a two-pane configuration with one fixed and one sliding panel. The sliding patio doors give access from the new master bedroom suite onto a small balcony looking over the rear garden.
The outer profile of the sliding patio doors where hidden within the building finishes both inside and out. Externally timber cladding was used to the roof of the small patio and tiles were used for the floor and wall coverings.
The slim framing of the minimal windows was especially useful for this small doorway to maximise the glass. With such a small door opening you want to ensure the most minimal framing and largest glass surfaces possible for that connection to the exterior.
Both the ground floor and the loft sliding glass doors were created using the Keller minimal windows system with double glazed insulated units within both.
The corner pocket doors and loft extension sliders were both finished in a dark grey powder coat RAL colour.
The type 2 manual lock was used on both the loft extension sliding doors and the corner opening patio doors to the ground floor. This manual locking system is only accessible from the inside of a building and provides an extremely secure PAS24 certified locking system.
