Hi, we’re KM Arch Studio, a small, independent residential design practice in Westwoodside, Doncaster. We help homeowners, families and a handful of small developers across South Yorkshire, North Lincolnshire and the villages in between.
Every project starts with a friendly, proper chat: what you need, what your home can realistically take on, roughly what it might cost and what needs to happen first. From there we prepare the drawings and information your job needs — a smarter extension, a planning application, or a whole new home from an empty plot.
KM Arch Studio is a small, independent practice in Westwoodside, Doncaster. We design extensions, alterations, planning drawings and new homes across South Yorkshire and North Lincolnshire.
We’re an independent practice, working with homeowners, families and a handful of small residential developers on extensions, alterations, planning applications and new homes.
We’re here to make good design easy to understand. That means telling you what’s happening and when, being straight about what is and isn’t included, and never dressing a proposal up as more certain than it really is.
No two houses are the same and no two briefs are either. So we start with your home as it actually is — its proportions, its light, its awkward corners — and build the design out from there.
Kirolos runs the studio and works on every project himself, from the first conversation to the drawings that go to the council.
As a Chartered Architectural Technologist, he looks after the technical and regulatory side of residential design. If your project needs an architect, a structural engineer or another specialist, he’ll tell you so plainly.
Tell us about your projectModern where it makes sense, right for the house, the street and the area — never dropped in from a catalogue.
We test layouts properly. Everyday life, storage, light and movement come before surface finishes.
The studio stays small on purpose. Your project isn’t passed round an office — the person you speak to does the drawing.
You’ll always know what stage we’re at, what we need from you and what happens next, with everything set out in writing.
Every decision is made against what’s actually possible: the building, the planning context and what you can sensibly invest.
We talk through your ideas, your house and what you’re hoping to achieve, then agree the work and the fee before anything starts.
We look at the building, the measurements you have and anything that might hold the design back, then work out what information we’ll need.
We sketch options and refine them with you — layout, shape, elevations and materials — within the scope we’ve agreed.
We prepare the drawings and supporting information, and help with the application as set out in your brief.
Every project is a little different, so the stages, drawings and information get confirmed in writing before we start. And planning decisions rest with your local planning authority — nobody can promise an approval.
Four areas of work. Each one has its scope, inclusions and exclusions written down before you commit — and if your project needs structural engineering, Building Regulations drawings or another specialist, you’ll hear it from us early, not halfway through.
Rear, side and single-storey extensions designed around your home, your garden and how your family actually uses space.
Existing and proposed plans, elevations, site plans and the supporting information your application needs — drawn carefully and checked before it goes in.
Concept design and planning-stage drawings for a new home on your plot, shaped around your brief and what the site can take.
Rooms reworked, circulation improved, dark corners opened up — a better home without the upheaval of moving.
What sits outside our standard work: Building Regulations applications, structural calculations, construction-level drawings, Party Wall matters and project management aren’t included unless we agree them separately in writing — most can be arranged, so just ask. And planning permission is never guaranteed: that decision belongs to your local planning authority.
Tell us about your property and what you’d like to do. We’ll say which route probably applies — and whether you’re likely to need planning permission.
Photographs and visualisations from residential projects — each one labelled with the stage it reached, so nothing is presented as more than it is.

ConceptImages show residential design work by Kirolos Malak. Concept, proposed and planning-stage work is labelled as such and may differ from anything built on site. More project photography is on its way — ask if you’d like to see examples close to your own project.
Straight answers about planning, drawings and what’s involved. Every project is different — if your question isn’t here, just ask.
Not always. Some extensions and alterations fall under permitted development, while others need a householder planning application. It comes down to size, position and height, the type of property, whether permitted development rights have been removed, and where the property sits. Tell us what you have in mind and we’ll say which is likely to apply.
Usually existing and proposed floor plans, existing and proposed elevations, a site plan and a location plan — plus sections or a design and access statement where they’re relevant. Each council asks for slightly different things, so we agree the drawing package with you before work begins.
Most extensions, structural alterations and new homes do. It’s a separate approval from planning permission, normally handled with detailed construction drawings and input from an engineer. Building Regulations work isn’t part of our planning-stage service unless we agree it separately in writing.
If you’re taking out load-bearing walls, adding steel beams, forming new openings or changing the structure in a significant way, you’ll normally need calculations from a qualified structural engineer. We flag it early so it can be priced and planned alongside the design work.
No — and no architect, technologist or practice can. Decisions are made by your local planning authority against national policy, the development plan and local considerations. What we can do is prepare accurate, clearly presented drawings and information so your application is properly made and fairly considered.
It depends on the scope: the type of project, how many drawings are needed, whether an application is required and how much development work is involved. We confirm the scope and fee in writing before starting. Council application fees are separate and paid to the council directly.
Design work usually takes a few weeks, depending on complexity and how quickly decisions get made. Councils publish their own determination periods and some applications take considerably longer. We’ll give you a realistic programme for our part of the work at the outset.
Doncaster, South Yorkshire, North Lincolnshire and the areas around them. If you’re further afield, get in touch — projects are considered case by case, depending on the type of work and the involvement needed.
Helpful, but not essential: a rough idea of what you want, any measurements or plans you already hold, a few photos of the house and garden, and a sense of your budget and timescale. A first conversation works without any of it — it just makes the discussion more useful.
We read every enquiry ourselves and reply the way you’ve asked us to, usually to clarify a few things about the property and the project. If it looks like a good fit, we’ll suggest a short conversation and then set out the proposed scope of work and fee in writing.
A few lines is plenty. Every enquiry is read by Kirolos and answered personally.
We work across Doncaster, South Yorkshire and further afield, case by case. There’s no public office address — enquiries are handled by phone and email, with site visits by arrangement.
