Preserving the past, engineered for the future.

At Muller Holding, we view heritage buildings not as obstacles, but as assets requiring stewardship. Our specialized restoration division is dedicated to the conservation and revitalization of historic structures, primarily focusing on Victorian and Edwardian properties in Manchester and London.

We bridge the gap between strict conservation requirements and modern functionality. Our team navigates complex planning regulations to deliver projects that honor the original architectural intent while discreetly integrating the safety, thermal performance, and technology required for 21st-century use.

Our Expertise by Restoration Discipline

Heritage work requires a specific set of traditional skills combined with modern structural engineering.

1. Facade Cleaning & Masonry Repair

Restoring the external envelope to its former glory. We use non-abrasive cleaning techniques and traditional materials to ensure longevity.

• Key Features: DOFF/TORC stone cleaning systems, traditional lime mortar repointing (essential for breathable historic walls), and replacement of damaged terracotta or stone details using hand-carved matches.

2. Structural Stabilization & Strengthening

Many historic buildings suffer from settlement or structural fatigue. We implement invisible strengthening solutions that preserve the building’s aesthetic.

• Key Features: Installation of steel ties and restraint straps, timber treatment for rot and beetle infestation, and underpinning of subsiding foundations.

3. Adaptive Reuse & Conversion

Transforming historic shells into modern assets. We specialize in converting old warehouses, mills, or townhouses into high-specification apartments or offices.

• Key Features: Acoustic separation between floors (critical in timber-framed buildings), fire compartmentation upgrades, and the creation of open-plan layouts while retaining original cast-iron columns or beams.

4. Modern Systems Integration

The challenge of making a 19th-century building work for a 21st-century user. We integrate modern utilities without damaging the historic fabric.

• Key Features: Routing data and power cabling through floor voids to avoid chasing into historic walls, installing slimline double glazing (vacuum glass) into original sash frames, and discreet ventilation systems.
