The Design Process

Hermitage Mews is a series of 8 high-quality townhouses designed by our emerging practice to achieve Net-Zero targets. The development features a mix of 3 and 4 bedroom terraced and semi-detached houses on a complex and constrained narrow, sloping plot addressing a busy road, Beulah Hill. These dual and triple-aspect split-level homes engage with the surrounding context through front forecourts addressing Beulah Hill and creating some truly beautiful and energy efficient homes. The project showcases the ambition and impact of small architectural practices and small site developers in London.

Initially conceived by Nissan Richard's Architects, our practice took over during the COVID-19 lockdown, reimagining the design to future-proof the homes, now to accommodate new requirements including remote work and home schooling. The homes are therefore designed to be adaptable spaces, incorporating a Home Office or a combined Living/Dining/Kitchen area, which have been optimised for extended use through considered natural light positioning and enhanced acoustics to buffer the noise pollution from Beulah Hill via triple-glazed windows.

Multi-coloured hand-moulded clay-facing brick with a sanded-coated finish was specified, bringing immediate texture and a sense of character to the new builds which sit in the context of existing heritage buildings. The homes are set back further from the street and host forecourts to encourage neighbourliness with rich planting to enhance biodiversity.

Sustainable design was central to the project, designed to achieve the RIBA's 2030 Climate Challenge. The homes employ a fabric-first approach, achieving an average u-value of 0.10W/m2K to reduce operational energy, and are built using timber structure and woodfibre insulation to minimise embodied carbon. This is a fossil-fuel free scheme with installation of Air Source Heat Pumps, PV panels and a robust ventilation strategy including an MVHR to ensure maximum occupant comfort. Green roofs and hedgehog corridors improve biodiversity on site.

Key Features

We adopt Regenerative design principles (doing net-positive good); embracing environmental, social and economic aspects.

Environmentally, the homes go beyond sustainability by generating electricity, and retention of existing trees and planting new ones increase biodiversity.

Socially, we organised students from the Bullers Wood Girls School to visit the construction site and meet the all-female construction team including QS, Head of finance, Project Manager, Contracts Manager and Architect.

With a focus on human health and wellbeing, the homes incorporate split-levels that bring natural light deep into the floor plans while moments of delight are expressed through unexpected double and triple height spaces.

Sustainability

The scheme has been designed to achieve the RIBA 2030 Climate Challenge targets with low operational energy and embodied carbon goals. The homes adopt a fabric-first approach to all walls, floors, and roofs have an average u-value of 0.10W/m2K with thermal bridge-free details to reduce the buildings’ Energy Use Intensity (EUI) – which was modelled as using 34kWh/m2/yr (RIBA =<35kWh/m2/yr). Bio-based materials such as woodfibre insulation has been used to increase thermal mass to reduce heat loss and aerated concrete blockwork to increase the fabrics’ insulating properties. Renewable energy via an Air Source Heat Pump (ASHP) provides space heating and hot water, and 40% of the roofs are covered with solar PV panels – making the scheme fossil-fuel free. Overheating analysis was undertaken using TM59 methodology with each home passing. Airtightness is <3 m2/h.m2@50pa and Mechanical Ventilation with Heat Recovery (MVHR) installed to maximise occupant comfort. Low embodied carbon is prioritised using timber construction to internal structures including party and internal walls, as well as the main structural elements. Glulam beams are used in place of steel and where steel was critical, flitch beams are used in its stead. Woodfibre insulation is used over PIR to further reduce impact. The building was redesigned to simplify the grid structure leading to a reduced building weight and resulting in less concrete required for foundations. Concrete foundations were designed to have a recycling content of 25% GGBS. High-performing windows and doors are from European suppliers with renewable energy as main energy generation. Aluminium-timber composites were specified to reduce the long-term maintenance of these elements – further reducing embodied carbon. Green roofs and hedging to the front and rear of the homes enhance the site’s biodiversity while contributing to the neighbouring wildlife corridor; including hedgehog corridors and bird houses on site.
