Timber-Clad Panoramic Extension by Mata Architects in Hampstead

This article highlights Panoramic House, Mata Architects’ timber-clad extension to a Hampstead family home. It explains how the new addition steps with the land to connect the house more closely to its garden and respects mature trees.

The project uses a restrained material palette and smart climate strategies to create an indoor–outdoor living space.

Site-specific design approach and massing

The project sits lower than the main living area, reducing a former 1.5-metre height difference. This eliminates a long flight of stairs between levels.

This change broadens the connection to the garden while maintaining the house’s architectural hierarchy. The extension follows the natural slope, preserving the topography and landscape character.

Connecting with the landscape

The siting responds to the mature trees on site, balancing openness and privacy. The layout is guided by the treeline and long-term tree health.

Tree-care specialists defined root protection zones to ensure roots are respected and protected. This allows the building to feel intertwined with the landscape.

Tree protection and topography

The design emphasizes a calm relationship with nature, where soil, roots, and canopy interact with the new timber form. By stepping with the contours and maintaining the existing vegetation, the design creates a sense of verdant enclosure.

This enhances shade in summer and protection from winds in winter.

Form, shading, and materials

The volume is wrapped in timber battens and topped with an overhanging, tapering roof. The roof shades the interior during warmer months and helps reduce heat gain.

A mirrored surface beneath the roof reflects the garden and trees, further integrating the extension with the landscape. This also multiplies the sense of space.

Glazing, light, and climate control

High-performance glazing paired with a sheer curtain provides flexible control over daylight, views, and heat. The glazing system balances daylight with privacy and reduces reliance on artificial lighting and cooling.

Interior palette and finishes

Inside, the design uses a restrained palette of natural materials to unify the old and new parts of the home. Timber floors, oak joinery, and wall panels create a cohesive, warm atmosphere.

Limestone in the bathrooms introduces a cool, tactile contrast.

Indoor–outdoor living and glazing details

At the heart of the plan is a glazed corner with large sliding doors that can be fully opened to merge the interior with terraces and the garden. This seamless expansion encourages open-air dining, lounging, and play while preserving a sense of shelter and comfort inside.

Impact, performance, and photography

By positioning the extension at a lower level and weaving it into the site’s contours, Mata Architects achieves a design that feels part of Hampstead’s landscape rather than a separate addition.

The approach demonstrates how careful massing and responsible tree protection can deliver a sustainable, climate-responsive home with strong connections to nature.

The restrained material language supports this goal.
