Mark Muir is one of the leading , outstanding and best architect in the UK. A highly professional with in-depth knowledge in house remodeling.
Mark can create extra or spare room from nowhere regardless of the size of your rooms. He help us to convert a 3 bedrooms detached house into 8 bedroom house without the need of new and costly foundations just by using loft space, remodeling the corridors and staircase layouts.
Mark's knowledge of building regulations had massively contributed into the approval of our planning application without objections or request for changes from the planners or Building Control.
An Excellent Architect and I highly recommend his practice and services to anyone who want to add value to his / her house through house remodeling.
Kind Regards

Living – Bespoke New Homes
Beautiful, sustainable homes designed around you.
At Mark Muir Architect, we create bespoke new homes in close collaboration with our clients. From the very first conversation, we listen carefully to your needs, passions and aspirations, and translate them into a home that’s both inspiring and practical.
Whether your project is large or modest, our approach is the same: to fully understand your vision and then explore creative, sustainable options that exceed expectations.
Every project begins with our Needs and Options Review – your personal “Blueprint to Success.” This simple, structured process helps clarify design ideas, budget and programme, giving you a clear route map forward without stress or confusion.
Sustainability is never an afterthought. We integrate nature-based solutions and natural materials into our designs, creating homes that are environmentally responsible, cost-efficient, and beautifully crafted.
We also understand the complexities of the planning system and have an excellent track record of gaining approvals in sensitive locations – including conservation areas, green belts and challenging urban sites.
From one-of-a-kind contemporary houses to small developments, we bring design excellence, creativity and delivery expertise to every project.
Your dream home starts with a conversation. Let’s create it together.

Barn Conversions
Transforming rural character into contemporary living.
More and more people are choosing to create their dream home in the countryside, and barn conversions are the perfect way to combine rural charm with modern comfort. At Mark Muir Architect, we specialise in unlocking the potential of barns — whether through Class Q (Permitted Development) routes or full planning applications.
A barn conversion is more than just a building project: it’s about breathing new life into a beautiful heritage structure, preserving its character, and turning it into a home that’s light-filled, practical and inspiring. We know how to maximise these often under-valued rural assets, creating unique homes that blend history, sustainability and contemporary design.
If you’re considering a barn conversion, we can guide you from the very first step — helping you navigate planning, explore design options, and deliver a home that exceeds expectations.
Your countryside home starts here.
