Architect · Derry · Donegal · North West

New homes and extensions designed around the way you live.

Whether you're building a new home or making more of the one you already have, I can help you create somewhere that looks beautiful, feels right and works for everyday family life. I'm Kristian Mitchell, an architect with over 25 years' experience helping homeowners across Northern Ireland and Donegal bring their ideas to life.

Let's talk about your plans

25+ years designing family homes · ARB · RIBA · MRIAI (IRL)

Maybe it's a kitchen where everyone naturally gathers. A living space filled with light. Somewhere the children can have their own space, or simply a home that makes everyday life easier.

Good design starts with understanding how you want to live, then making the most of your space, your surroundings and the things that matter to you.

It's about creating a home you'll enjoy for years to come.

A home that works the way your family does.

You know what you want your home to feel like. Getting there is the hard part.

Maybe it's a site in the country. Maybe it's the old homeplace that needs replacing, or a house you love that no longer fits the family.

You can picture the life you want in it. What's missing is a clear view of what's possible, what it will cost and where to begin, and you're working that out alongside careers, children and everything else.

What your site or house allows. Every site has its own rules. Near the border, two different planning systems can apply a few miles apart.

What it will cost. A good design is shaped by your budget from the first sketch, so there's no painful cutting back later.

Who to trust with it. You want one person who looks after the whole thing, explains each step and tells you straight.

Building or reshaping your family home should be one of the best things you do. It shouldn't take over your life

I've helped families do this for more than 25 years, and I've done it for my own.

I'm Kristian Mitchell. We have outgrown the house and needed more space, so I know what it's like to make these decisions at the kitchen table, with a budget you've worked hard for.

For more than 25 years I've designed one-off houses, replacement dwellings and extensions across Northern Ireland and Donegal.

I work under both planning systems, so if your site is near the border you deal with one architect who knows both.

I'll help you see what's possible, design a home around how your family lives, and stay with you through planning, the technical drawings and the build.

Three steps from first idea to moving in

1. Have a free 15 minute call. Tell me about your site or house and what you're hoping for. I'll tell you honestly how I can help and what a sensible next step looks like.

2. Book a Project Clarity Review. I visit your site or home, look at planning, budget and what's possible, and give you a written plan you keep. £450, credited against the design fee if you appoint me within 12 months.

3. Design it, get permission, build it. We shape the design together, then I take it through planning, the technical drawings and onto site.

What I design.

New Houses.

A home that's yours from the very beginning.

Building your own home is an opportunity to create something truly personal. From the way it sits within its surroundings to how each room connects, I'll help you develop a design that makes the most of your site and reflects how you want to live.

Extensions & Renovations

Love where you live.

Make more of it. Sometimes the right home is the one you're already in. Whether you need more room for a growing family, a better connection to your garden or a completely different layout, I'll help you see what's possible and make the most of what you have.

The choices made in the first few weeks shape the cost, the planning outcome and how the house feels to live in. It's worth making them with someone who has done it many times.
