Architect Peter Morris has completed Cloud House, a pair of bespoke semi-detached dwellings featuring distinctive scalloped parapets and pastel facades in Gospel Oak, north London. The project replaces an uninhabitable Victorian residence previously occupied by the designer, concluding a decade-long development process spanning detailed planning negotiations, community decorating efforts, and bespoke exterior mouldings.

What was built in Gospel Oak

The finished project occupies a residential plot south of Hampstead Heath, introducing two adjoining properties where a single dilapidated dwelling once stood. One of the newly built houses provides a private home and workspace for Morris and his partner, television producer Emily Kennedy, while the matching adjoining property accommodates independent private purchasers who began moving in upon practical completion.

Arranged across three storeys, the main volume matches the prevailing building heights and building lines of the surrounding streetscape while establishing an unmistakable visual identity. The top parapet line sweeps into undulating scalloped curves finished in soft pink, giving the upper roofline a cloud-like outline when viewed against the skyline. Accompanying elevations incorporate delicate green elements, rhythmic arches, and deep window reveals that contrast with conventional north London street elevations.

The ground level provides expansive shared living accommodation alongside a dedicated studio for Morris's architectural practice, orienting social areas towards a ground-level courtyard designated for kitchen planting. Above, the first and second levels contain sleeping quarters, utility rooms, and family bathrooms. Circulation finishes at the highest level with an operable glazed skylight over the central stairwell, providing direct egress to an enclosed roof terrace that functions as the property's primary open-air amenity space.

The background and planning context

Before redevelopment, the plot contained a worn-out Victorian brick house where Morris and his family previously resided. Decades of deferred maintenance and severe rising damp had compromised the structural fabric, making comprehensive repair economically unviable and technically inefficient compared to modern thermal expectations. Morris elected to seek permission for a pair of bespoke replacement dwellings, approaching the London Borough of Camden to negotiate an appropriate replacement form.

Camden Council's planning officers engaged in discussions across several years, evaluating how an idiosyncratic architectural expression would assimilate into a complex urban setting. The street exhibits an eclectic heritage condition: immediately opposite stands the parish church of St Martin, an ecclesiastical landmark holding a Grade I statutory listing, while the immediate streetscape also hosts a Grade II-listed French school, standard 19th-century domestic terraces, and contemporary residential infill blocks.

Rather than mandating pastiche Victorian detailing, municipal planners recognised that the variety of local building typologies supported an expressive individual scheme. Camden accepted that Morris's direct personal investment in the project added architectural authenticity to the townscape. While the protracted design review and permitting process extended the overall project delivery across ten years, the fundamental massing, arched geometries, and signature roof profile survived municipal scrutiny intact.

The architectural design and construction

Structurally, the building utilizes a straightforward primary frame formed from standard blockwork, concrete floors, and facing brickwork to ensure acoustic privacy and load-bearing stability between the two semi-detached units. The sculptural exterior articulation was then achieved through an innovative lightweight envelope system, bypassing the structural weight and prohibitive costs associated with carved natural stonework or precast masonry elements.

The external skin relies on high-density shaped polystyrene stone elements attached directly to the primary substrate. This composite system delivers dual advantages: it contributes significantly to the external thermal envelope without thermal bridging, while remaining easily workable on site. The shaped substrate was finished with an exterior textured render, creating a monolithic, weather-resistant outer skin that mimics traditional mineral finishes while remaining highly resilient.

Geometric arched openings across the external skin take design cues from the pointed window heads and masonry details of the adjacent St Martin's parish church, transposing historical ecclesiastical forms into domestic architecture. On the upper terrace, the undulating parapet creates an enclosed, secluded outdoor environment that shields occupants from wind and street noise while directing sightlines upward toward the Hampstead Heath tree canopy.

Internally, Morris drew inspiration from historic British interiors, incorporating round plaster spheres across walls and joinery that mirror decorative techniques seen at Sir John Soane's Museum in central London. Murals, structural arches, and internal pass doors share identical radiused silhouettes, aligning with previous design studies documented in earlier coverage of Peter Morris completing the scalloped Cloud House in Gospel Oak. Bright interior stripes and saturated wall paints extend the playful, narrative-driven exterior language deep into the family living rooms.

Financial strains during extended construction phases prompted Morris to organise collaborative working sessions, with friends, family members, and local residents assisting on site to complete final interior painting, woodwork priming, and decorative finishes in time for handover.

What people are saying

Throughout the municipal consultation, Morris reported strong support from Camden Council's planning team, who welcomed the transparent display of the architect's personal design sensibilities rather than demanding standard speculative development forms. Morris observed that while his commercial practice usually moderates eccentric details in favour of restrained palettes, building his own home provided a rare opportunity to maintain bold graphic intentions without dilution.

Reflecting on the decade-long endeavour, as first reported by Wallpaper* architecture, Morris noted that the home serves as an architectural manifesto for domestic joy. "The Cloud House is a colourful, joyful place, but it is also a statement about what residential architecture can be," he observed.

Neighbouring residents and craftspeople who assisted with final site preparation praised the injection of warmth into the urban block, where traditional red-brick Victorian façades dominate the majority of street frontages.

What happens next

With practical completion achieved and both halves of the semi-detached building occupied, Morris is turning his attention to external landscape refinements. Immediate exterior works involve fitting out the sunken courtyard at ground level with raised planters, timber benching, and culinary herb gardens to complement the upper roof terrace.

Morris also intends to use the Gospel Oak project as a template for prospective clients looking to commission tailored residential infill schemes across Greater London. Having navigated Camden's planning system to secure support for non-standard colours and undulating geometries, his studio plans to demonstrate how inventive material specifications, such as insulated rendered mouldings, can unlock sculptural design on challenging urban sites without exceeding conventional residential construction budgets.

Why this matters

Cloud House illustrates how local planning authorities in London can embrace expressive, non-traditional architecture on sensitive urban sites containing listed heritage assets. By borrowing geometric rhythms from nearby ecclesiastical landmarks and matching prevailing street massing, the project proved that bold colour and non-standard forms can secure approval under standard planning policies. It also demonstrates how innovative lightweight cladding methods can make complex, sculptural facades financially achievable within one-off residential budgets.
