Collaboratively working with designers and freelancers to create the Grain Architecture Team.

Janna Laan Lomas

Janna founded Grain Architecture in 2015, after completing her Part II Prof Dip in Architecture at the Centre for Alternative Technology (CAT). She started Grain to meet a demand for building with a strong focus on designing for long-term environmental responsibility by using natural materials, and avoiding plastic and cement wherever possible. She also co-founded NBUK (Natural Building UK), which is a non-profit organisation educating public & industry about the use of natural materials in construction. 


Janna is driven by the creativity of designing spaces and has been drawing houses since the age of about 6 (she loves a floor plan and problem-solving layouts!). She's passionate about beautiful buildings and gardens, and excited by opportunities for making a positive impact on lives and landscape through architecture and rural community development. 

Founding Director & Designer

Andy Hales

Andy joined the team in 2019 and is working full time with us in Godalming. Since Part I at Cambridge University, Andy has been working with small practices on a range of projects, including domestic renovations, extensions and new builds, ecclesiastical projects, and the renovation of a civic centre.


After Part II at CAT (Centre for Alternative Technology), Andy spent time working with a conservation architect and ran a straw bale self build. He worked on a number of freelance projects including a self-built, timber frame bungalow insulated using natural building materials. He is currently doing his Part III with Bath University.

Andy aims to design honest, highly sustainable buildings that are user friendly, healthy and simple to construct. He enjoys making interesting spaces filled with natural light.

Kirsty Cassels

Kirsty is an experienced Part II architectural designer from the South West coast of Scotland. She studied her BArch part time at the Glasgow School of Art while working full time in an Architects office and she studied her DipArch at the Centre for Alternative Technology (CAT) where she met Janna. She has over ten years experience of working in practice for several different practices on projects ranging from small domestic extensions, to large multi million commercial developments. She does occasional work with Grain on a freelance basis from her home in Scotland. 

Her passion is working with natural building materials and making architectural design and building more accessible to the general public. She was Vice Chair and Director of the Scottish Ecological Design Association for two and a half years, and she has been involved in many live volunteer builds over the past seven years either as a participant or a teacher. She loves a good brick pattern and has a bond she designed and implemented on a project named after her in Sierra Leone! She also co-founded Building Together CIC, and won Social Entrepreneur of the Year at the Scottish Women's Awards 2019. 

Architectural Designer


Peggy is the 5 year old Tibetan Terrier who keeps us all in check. She tells us when it's time for lunch and when to stop work for the day. She also motivates us and de-stresses the office with her 'zen' vibe. She's a very clever dog with a Masters degree in Tricks and Office management, and is a real asset to the team. We're currently teaching her Vectorworks.
