Self-build homes & modern renovations.
Architect-designed self-build homes across Dundee, Tayside, Fife, Angus and beyond.
Self-build homes & modern house extensions.
Designing a home — whether through a self-build, extension or full renovation — is a chance to shape the way you live.
To create rooms filled with light, spaces that flow effortlessly, and a home that feels calm, warm and unmistakably yours.
At 125Architects, we help Dundee homeowners bring those ambitions to life through thoughtful, contemporary design rooted in craft, clarity and a deep understanding of place.
Contemporary self-build architects.
Every self-build project begins with a feeling: wanting more space, more light, more connection to the landscape, or the opportunity to create a home from the ground up that finally reflects who you are.
Dundee’s rich mix of Victorian villas, stone terraces, post-war homes and coastal plots gives every project a unique story.
We work closely with clients across Dundee and Tayside to design self-build homes that feel modern yet grounded, expressive and timeless.
From rural edge plots and replacement dwellings to garden infill sites, we guide you from the earliest feasibility studies through planning, building warrants, technical design and construction, ensuring every idea is carefully managed from concept to completion.
Our approach blends clean, contemporary architecture with natural materials, careful proportions and soft transitions between inside and outside — resulting in homes that feel peaceful, crafted and built to last.
Designing modern homes rooted in local character.
Dundee’s architectural landscape is wonderfully varied: stone terraces, Victorian townhouses, coastal homes in Broughty Ferry, 20th-century suburbs and former industrial buildings that hold layers of history.
Respecting this character while introducing light, clarity and modern comfort is essential to every project.
Whether you’re opening up a traditional property or building a home that engages with views towards the Tay, we shape spaces around how you want to live — morning light in the kitchen, quiet places to retreat, framed views of the garden and flexible rooms that grow with your family.
House extensions that transform the way you live.
A well-designed extension doesn’t feel like an add-on. It feels like the home finally works.
We create extensions that bring kitchens and living spaces into better harmony — bright, open, beautifully proportioned rooms that encourage gathering, cooking, hosting and reconnecting with the garden. From expansive glass additions to carefully detailed timber structures and subtle interventions to period homes, our extensions prioritise light, warmth and effortless day-to-day living.
Our services include self-build homes, house extensions, internal reconfigurations, whole-home refurbishments, loft and garage conversions; and energy-led retrofits that improve comfort and efficiency without compromising character.
Garden rooms & home studios.
Garden rooms are increasingly popular, offering flexible space for work, exercise, hobbies or additional family living and can sometimes be constructed without planning permission.
Our aim is to design structures that are permanent and efficient, not temporary — carefully proportioned, beautifully detailed and compliant with building regulations whilst seamlessly integrating into the garden setting.
