The development faced key planning challenges, as the site is designated as part of the District Green Infrastructure under Policy CS18 of the West Berkshire Core Strategy (WBCS) 2006-2026. Preserving the existing green infrastructure was essential, particularly the mature landscape buffer along the southwestern boundary, which enhances the garden centre’s visual appeal. To mitigate the impact of new structures, the council stipulated that any additions must remain single-storey and be complemented by high-quality landscaping. Addressing potential traffic congestion at the A4/Tull Way junction and ensuring adequate parking provisions were also critical considerations. In compliance with Policy CS15, the scheme is designed to meet a BREEAM “Excellent” standard, incorporating renewable energy solutions.

The design process was guided by a thorough analysis of the site’s constraints and opportunities. Existing structures, which include single-storey brick buildings with low-pitched roofs, contrast with the main garden centre’s rustic aesthetic of brick, timber, and sheet metal cladding. The proposal takes inspiration from these materials while introducing contemporary, sustainable elements. Existing road access will be maintained, with improved internal circulation to facilitate logical navigation and promote safe pedestrian and vehicular movement. The architectural approach respects local character while incorporating high-performance materials for greater environmental efficiency.

The final design delivers high-quality, sustainable buildings that complement the wider garden centre site. The proposal includes a drive-thru restaurant, small commercial start-up units (Use Class E(g)), and business/service spaces (Use Class E), strategically designed to meet current market needs while preserving the caretaker’s residential bungalow. The scheme also prioritises landscaping improvements, reinforcing a 10-metre green buffer along the A4 and Tull Way junction. This not only enhances biodiversity but also softens the development’s visual impact within the strategic gap beyond Thatcham’s settlement boundary.

Material choices reflect durability and aesthetic harmony with the surroundings. The buildings will feature Berkshire red-orange brick combined with insulated cladding panels, ensuring both visual cohesion and thermal efficiency. Windows will be aluminium-framed curtain walling, tailored to occupier branding requirements. The roof incorporates profiled metal with photovoltaic cells for renewable energy generation. These selections reinforce the development’s commitment to sustainability, functionality, and modern commercial appeal.

Sustainability is at the heart of the project, with a focus on energy efficiency and responsible construction. The development targets a BREEAM “Very Good” rating, with ambitions to achieve “Excellent.” Renewable energy sources, such as photovoltaic cells and air-source heat pumps, will be integrated, along with electric vehicle charging points to support greener transportation. Cycle parking will be provided in accordance with standards, encouraging active travel. The car park will feature permeable tarmac for enhanced water management, supported by low-level safety lighting to minimise light pollution. A Sustainable Drainage System (SuDS) is incorporated into the landscaping strategy, ensuring effective surface water runoff management.

Exceeding regulatory sustainability requirements, including the latest updates to Part L (Conservation of Fuel & Power) of the Building Regulations, the scheme takes a “fabric first” approach to energy conservation. Passive design strategies, such as brise soleil on western-facing glazing, will reduce solar gain and prevent overheating. Additionally, the project enhances local biodiversity, with the 10-metre buffer along the A4 featuring new tree planting, native hedging, and ecological improvements.

More than just a commercial expansion, this project represents a progressive step towards a more sustainable and dynamic local economy. By providing contemporary business spaces, it supports start-ups and established enterprises, fostering job creation and long-term economic vitality. The enhanced green infrastructure and energy-efficient design will contribute to a healthier, more attractive environment, reinforcing Thatcham’s position as a forward-thinking commercial destination that successfully integrates business growth with environmental responsibility.
