Andover Rear Extension
Timber-Clad Single-Storey Extension

This Andover cottage has been dramatically transformed with a contemporary single-storey rear extension, seamlessly blending modern design with the character of the original period property. The extension features vertical light timber cladding, a standing seam zinc-effect low-pitch roof, full-height aluminium glazing, and sliding bi-fold doors that open directly onto a new porcelain stone patio. Structural blockwork forms the core of the build, with premium timber cladding applied externally to deliver a striking yet sympathetic finish. The result dramatically increases living and entertaining space, floods the interior with natural light, and adds significant long-term value to this sought-after Hampshire home.

Before The Transformation

Andover Rear Extension

Before work began, this Andover cottage had an outdated lean-to structure at the rear that wasted valuable space and did little to make the most of the generous garden. The homeowners wanted to open the house up, bring in far more natural light, and create a large modern living and entertaining area connecting directly to the outdoors.

Working closely with the homeowners, we developed a full single-storey rear extension plan including demolition of the existing lean-to, new strip foundations, structural blockwork, a standing seam zinc-effect roof, vertical light timber cladding, full-height aluminium glazing, and bi-fold doors opening onto a new porcelain patio. The goal was to dramatically increase living space while delivering a contemporary finish that complements the character of this traditional Hampshire cottage.

The Finished Result

Andover Rear Extension — Completed

The transformation speaks for itself. What was once a dated, underused rear elevation is now a stunning contemporary living space — clad in vertical light timber, wrapped in full-height aluminium glazing and bi-fold doors that pour natural light deep into the heart of the home.

The standing seam zinc-effect roof ties the modern extension seamlessly to the existing slate of the original cottage, while the new porcelain stone patio creates a fluid connection between indoors and the garden. A complete rear transformation — built to last, built to impress, and adding significant value to this Andover property.

Before Extension Work Began

Before work started, this Andover cottage had an outdated lean-to structure at the rear with no modern connection between the house and outdoor space. The homeowners wanted to transform the rear elevation and create a large, light-filled living area opening directly onto the garden.

The brief was clear — build a contemporary single-storey rear extension with full-height glazing, bi-fold doors and a new patio, anchored by new foundations and a modern light timber cladding aesthetic that would complement the existing period cottage.

Groundworks & Structural Shell

Work began with demolition of the existing lean-to, excavation and new strip foundations laid to set the footprint of the extension. Strip footings were poured, blockwork started, and the full-height walls and steel beam went up to create the structural shell, with the low-pitch standing seam roof structure framed across the top.

Scaffolding was erected for safe access as the walls rose and the roof took shape. Large openings were formed for the full-height glazing and bi-fold doors. Every stage was completed with attention to detail to ensure strength, accuracy and a high-quality finish built to last.

Completed Andover Extension

The extension is now complete, delivering a fully transformed rear elevation with striking light timber cladding, full-height aluminium glazing, bi-fold doors and a new porcelain stone patio. The finished result has dramatically increased living space and natural light while completely modernising the rear of this Andover cottage.

By combining quality materials with expert workmanship, this Andover extension project has successfully opened up the home, connected it to the garden, increased its value, and created a striking contemporary space that complements the original character of the period property.
