The Value of 3D Models in the Architectural Design Process

With the rise of AI-generated imagery, powerful new tools are becoming increasingly accessible for communicating architectural ideas. While these technologies offer exciting opportunities to visualise a design, we continue to find that traditional physical models can be far more valuable during the architectural design process itself.

Over the past few months, we’ve been fortunate to welcome Oliver to the studio, an architectural student with a particular talent for architectural model-making. We’ve been putting his skills to good use, translating some of our more complex designs into physical models that allow us to explore and test our ideas in three dimensions.

Physical models offer a tangible way to interrogate a design, revealing qualities that can sometimes be overlooked when working solely with two-dimensional drawings or digital representations. They allow us to test massing, understand spatial relationships and identify potential flaws at an early stage, when changes can be made more easily and effectively.

For our St Philip’s Church project, we commissioned a 1:100 scale model showing the existing listed church alongside the proposed extension. Crafted from timber and card, the materials were deliberately chosen to contrast with the solidity and weight of the existing structure. The model beautifully communicates the delicacy of the proposed intervention, helping us understand how this contemporary addition sits comfortably alongside the historic building. Small details, including 3D-printed scale figures, bring the scheme to life and help convey a sense of scale and proportion.

We also find physical models invaluable when communicating our proposals during the planning process. Architectural designs often need to be understood by a broad audience, including people without a technical background in architecture. A physical model provides an accessible and intuitive way to communicate scale, massing and context, allowing people to engage with a proposal in a way that drawings alone may not always achieve.

For our Paddock House and Paddock Gardens project, we commissioned a 1:200 scale model to illustrate the extended house and proposed new dwelling within the garden plot. During the planning process, the model helped demonstrate the scale and relationship of the proposed buildings, showing how the design had been carefully considered in response to the character and scale of the surrounding village.

As architectural visualisation continues to evolve, we see physical model-making as an enduring and complementary part of the design process. Beyond simply presenting a finished idea, models allow us to question, test and refine our proposals, helping us make more informed design decisions and communicate our intentions with greater clarity.

For us, the value of a physical model lies not just in what it shows, but in what it helps us discover along the way.

 

St Philip’s Church submitted for planning

We are thrilled to have just submitted a detail planning application for a small entrance extension for the Grade II listed St Philip’s Church in Cosham, Hampshire. 

This is part of a detailed feasibility study we have undertaken, focusing on reimagining the existing spaces within the church while respecting and preserving the significance of this historically important building. A key area of investigation was the entrance and main nave, with proposals exploring how it could accommodate a flexible, multi-purpose environment supporting both worship and wider community use.

 

April Practice News

This month, we’re proud to share beautifully captured photographs of The Granary by Richard Chivers, along with news of the start on site at St Barnabas, and highlights from a recent event with the University of Reading School of Architecture.

The Granary completes

We’re delighted to share images of the recently completed The Granary, a truly unique project located near Burley in the New Forest National Park. The original property forms part of a late 18th-century agricultural model farm. While the building itself is not listed, it sits within the curtilage of a listed structure, which made the planning process more complex.

Our design carefully reworks the existing building, infilling the open carport at ground floor level to extend the living accommodation and bring the primary living spaces down to this level. This approach allows the first floor to accommodate more private functions.

The result is a generous and flexible ground floor, with the potential to create additional bedrooms as needed, supporting the long-term future of the building for its young owners.

Have a look at more completed photos here.

St Barnabas started onsite

Phase One of the church renovation is now underway on site. Located in the Knowle district, close to Bristol city centre, the church required reconfiguration to better support the needs of its local community.

This phase of work focuses on the interior, creating more accessible and flexible facilities, including an upgraded kitchen, private meeting spaces, improved WC provision, and a range of sustainable enhancements.

We look forward to sharing further updates as the project progresses, learn more about the project here. 

Reading University Lecture

Darren was invited to take part in the University of Reading School of Architecture’s latest lecture series, The Politics of Space, this month.

His presentation, titled Small Moves, Big Impact, explored how architecture and design can achieve more with less. The talk reflected on a number of key projects Studio BAD has delivered over the past seven years, with a particular focus on community-led work, including St Margarets Church, Bedford Place, and October Books.

Planning success for sustainable charging at Marwell

Studio BAD have worked in collaboration with University of Southampton to research, and achieved planning permission for fully off-grid electric charging within the Marwell Zoo customer car park, near Winchester in Hampshire.

Designed to deliver sustainable infrastructure to support the nationwide drive towards sustainable car charging, without adding a burden to the existing electrical grid, this project is a trail which we hope can be rolled out to more locations in the near future. This scheme is set to be live for three years, to test the unique, fully off grid electrical vehicle charging technology. Because of the temporary nature of the installation, the design does not involve the removal or alternation of any of the mature trees on the site, installing permanent foundations, or fixing, it has been designed to touch the ground lightly, and be removable.

In total the project will deliver over 20 car charging space, with solar panels installed on butterfly roofs, linked to battery storage, and a back up generator.

The design offering visitors to the zoo an opportunity to charge their cars sustainably. Supporting and aligning to the zoo’s strong commitment in this area, other initiatives include generating their own power through solar power, and their ‘Zoo Poo’ project which recycles animal waste to heat buildings.

The project works in collaboration with the FEVER research project, led by the University of Southampton in partnership with Universities of Sheffield, Surrey, and Portsmouth, and funded by the UK Engineering and Physical Sciences Research Council (EPSRC).

Courtyard House cladding update

On our most recent site visit to Courtyard House, we were thrilled to see the roof completed, the scaffolding removed, and the external cladding almost completed, marking another positive milestone in the construction phase.

The vertical timber cladding wraps the whole building, helping to blend the new structure into the rural setting. Two complementary timber finishes have been introduced to subtly break down the building’s massing and add visual depth.

The work is now shifting to the interior works, and we are very much looking forward to documenting how this projects continues to evolve onsite.

Studio BAD deliver RIBA CPD

We are pleased to annouce that Darren Bray will be delivering a RIBA CPD session, alongside Professor Lorraine Farrelly, on Laying the Foundations: Navigating feasibility studies for project success, as part of the 2026 RIBA Core CPD programme.

On this course they will be discussing the pivotal role feasibility studies play in delivering successful architectural projects. Learning outcomes will include:

  • Analysing site constraints, planning policy, budgets, environmental factors, and client briefs to inform project feasibility
  • Evaluating risks and opportunities for a range of project typologies, including new builds, retrofits, community assets, and housing
  • Genegrating feasibility study data into proposals that demonstrate project value, sustainability, and deliverability.

We really enjoyed working with the RIBA to put these together, find out more and sign up here. As part of the 2026 core programme you can learn on demand at a time that suits you, and complete the courses in any order.
