Self-Build

House

The Client’s Brief

The client sought to replace their existing single-storey bungalow with a larger, more efficient home that would provide three-bedroom accommodation whilst remaining affordable and sustainable. As a self-build project, the design needed to facilitate straightforward construction that the client could manage directly, working with specialist contractors on a cost-effective programme.

The brief emphasised energy efficiency, low running costs, and environmental responsibility through sustainable materials and construction methods. The timber frame construction approach would enable rapid build times whilst delivering excellent thermal performance. Despite the site’s rural location and position outside the village development limits, the client was determined to secure planning permission for a replacement dwelling that would serve their long-term needs.

The Design Solution

The design responds to the planning context with a compact, low-profile form that minimises visual impact within the countryside setting. Whilst arranged over two storeys, the dormer bungalow configuration keeps the ridge height modest, ensuring the dwelling sits comfortably within the rural landscape without appearing intrusive or out of scale with its surroundings.

The plan remains deliberately simple and efficient, reducing both construction costs and ongoing maintenance requirements. Ground-floor accommodation includes a modest side extension housing utility and bathroom facilities, finished in render to complement the main structure. A rear glazed garden room creates a strong connection between internal living spaces and the garden, flooding the home with natural light whilst providing easy outdoor access throughout the year.

Material choices prioritise sustainability and natural weathering. Untreated larch wall cladding, sourced locally from the Stourhead Estate, will silver naturally over time, developing a characterful patina that integrates the building into its landscape context. Clay roof tiles provide durability and visual warmth, whilst the timber frame construction delivers excellent thermal performance with minimal environmental impact.

Overcoming Planning Challenges

Securing planning permission for a replacement dwelling outside development limits required careful justification. The design strategy focused on demonstrating that whilst the new home provides significantly improved accommodation, its visual impact remains controlled through the compact footprint and low-profile dormer configuration.

The two-storey arrangement delivers the required bedroom accommodation without excessive lateral spread, maintaining a building envelope that respects the site’s rural character. This approach satisfied planning concerns about countryside protection whilst enabling the development of a far more suitable long-term family home.

Construction & Sustainability

The timber frame system, designed by specialist engineers, enabled rapid construction whilst delivering exceptional thermal performance. This approach proved ideal for a self-build project, allowing the client to coordinate trades efficiently whilst maintaining quality control throughout the build programme.

Sustainable design principles inform every aspect of the home. The timber frame construction minimises embodied carbon, whilst the natural materials require minimal processing and will weather gracefully without regular maintenance. The compact plan and high-performance building envelope ensure low energy consumption, whilst the south-facing glazed garden room maximises passive solar gain during cooler months.

Key Features

This project successfully demonstrates that high-quality sustainable housing remains achievable within realistic budgets. Self-build procurement, combined with efficient design and construction methods, delivered an affordable home with low running costs and minimal environmental impact. The dwelling will require little maintenance over its lifetime, with the untreated larch cladding developing its natural silver patina and the durable roof tiles providing decades of weather protection.

The contemporary reinterpretation of traditional building forms creates a home that feels rooted in its Somerset countryside context whilst offering thoroughly modern living standards. Natural light, efficient planning, and strong garden connections combine to deliver accommodation that will serve the client’s needs for many years to come.
