 Trustindex verifies that the original source of the review is Google. Fantastic service from first call to final signoff. All stages of the design were prompt and collaborative. Final result has been amazing and Robyne and Chris were very quick and helpful to jump in and help get building sign off pushed through when needed.

 Trustindex verifies that the original source of the review is Google. We used Plans to Extend, after a recommendation from friends. Really helpful in guiding us through the process I'll get in a wall taken down and all of the drawings, structural engineering import and taking it through building control. Amounts of time by them knowing all about these and explaining things in a straightforward way. They also worked really hard to meet her deadlines. Great job!

 Trustindex verifies that the original source of the review is Google. What an outstanding service and fantastic people to deal with. I have an extensive chat and was given very valuable information on our project. Sadly not what we needed to hear and we're rethinking our options, but the service so far has been outstanding and I have no hesitation but to recommend.

 Trustindex verifies that the original source of the review is Google. "We recently worked with Chris Marsden team on our home extension project, and the experience was outstanding from start to finish. Their design perfectly balanced functionality and aesthetics, transforming our vision into reality. They handled the entire planning process seamlessly, securing both planning permission and building control approval without any stress on our side. Communication was clear and timely, and every detail was thoughtfully considered. We couldn’t be happier with the result and highly recommend Chris for anyone looking for a skilled and reliable architect."

 Trustindex verifies that the original source of the review is Google. We are so lucky to have chosen Chris as the planner for our restaurant. From our first meeting up until the present day Chris has been so helpful with all our questions ( and there’s been a lot) He goes above and beyond to help us and spent hours sourcing companies to help us with a dilemma when the council put up obstacles. Always helpful always happy always willing. His knowledge is impeccable and if he doesn’t know he will find someone that does. We couldn’t be happier and would definitely recommend him on any planning venture.

 Trustindex verifies that the original source of the review is Google. My wife and I had a consultancy call with Chris to go through our plans for a two story extension. Chris was very helpful and provided very good advice on our extension plans. He also talked us through how the process would work from planning to building including estimates on costs and expected timeline to completion. Would highly recommend.

Your Conversion Journey In Four Clear Steps

Whether it’s your loft conversion or garage conversion, the journey is the same: four simple stages that take you from idea to a fully approved, compliant conversion in Greater Manchester.

Step 1: Discovery Call

We discuss your ideas, assess the feasibility, and walk you through the entire process, all before you commit to anything.

You'll know what's achievable, what it costs to get approved, whether we can guarantee loft conversion planning permission and give you a clear path forward.

Step 2: Survey & Design

We visit your property, measure your loft or garage, and deliver your loft conversion plans or garage conversion plans within 28 days.

You'll see exactly how the space works, how we're maximising headroom and natural light to make your room feel bigger and brighter, and what your finished conversion will look like before a single brick is laid.

Step 3: Planning

We check what's allowed under loft conversion permitted development rules and handle any required submissions.

If loft conversion planning permission is needed, you have everything prepared for you, submitted to your local council, and your approval guaranteed. Refused? We revise and resubmit at no extra cost so you never waste time or money on rejected applications

Step 4: Building Control

We manage the technical requirements for you: structural calculations, loft conversion drawings, and submissions to Building Control.

Everything is compliant, passes inspections, and gets legally signed off. Your builder receives clear loft conversion floor plan drawings they can work straight from, and your resale value stays protected

Want Us To Manage Your Build Too?

Your loft conversion plans are approved. Now you need a builder you can trust, but choosing the wrong one is where most conversions go wrong.

The structural work doesn’t meet Building Control standards, the headroom’s off, and the insulation fails inspection. When you sell, your conversion has slashed your property value, and the builder’s long gone with your money.

That’s exactly what we prevent.

Once your loft conversion planning permission and Building Control approval is secured, you get vetted builders sourced for you, estimates gathered, and the choice of who to work with. You have us attend the first meetings, agree fixed prices, and set up a legal contract that protects you. You get on-site support for every Building Control inspection to confirm your conversion meets regulations, the quality is solid, and your property value stays protected.

You need to know what it’ll actually cost to turn your loft or garage into a proper room in Greater Manchester.

What Affects Your Conversion Costs

Size and complexity

A small garage conversion costs less than a full loft extension costs project with dormer windows and an en-suite. Use our free cost calculator to get an instant estimate.

Structural work

Reinforcing loft floors, adjusting roof structures, or upgrading garage foundations increases build costs. This applies whether you're planning a basic loft conversion or a full dormer with an en-suite.

Finishes

Budget-friendly materials keep costs down. Premium kitchens, bathrooms, or high-end flooring cost more and this is true of any loft conversion and extension project where the spec drives the final price.

Loft vs garage

loft extension cost is typically higher due to roof work and staircase installation. Garage conversions are simpler and faster, making them a cost-effective alternative. Read our FAQ on costs and timelines .
