Existing Drawings

Looking To Convert Your Property Into An HMO?


Before You Start, You Need Reliable Existing Drawings

If you’re looking to make changes to a property, one of the first things you need are Reliable Existing Drawings. 

Without it, you can’t reliably make design changes and improvements to the layout to maximise cash flow. 

Whether it’s your house you’re looking to convert to an HMO (house of multiple occupation) or investment property, you need accurate, detailed drawings. 

A Change of Use Application MUST be accompanied by Existing and Concept Drawings

Accurate Existing Drawings, help you answer important questions like:

  • Do the current room sizes comply with Local HMO Regulations?
  • What if you can only fit 5 bedrooms instead of the 6? How would that affect your cashflow?
  • Can you actually fit a dormer loft conversion for an extra room?


Our expert team can take care of the full HMO development journey for you, from conceptplanning & building control, through to construction.

HMO Architect offers design consultation calls, concept drawings, interior design, and other services to help you every step of the way. We complete all projects to the highest quality to suit your needs and ideas.

The Solution?- Detailed Existing Drawings

Existing Drawings - How It Works


Step 1:

HMO Architect will book in a Measured Survey where our surveyor takes accurate and detailed measurements of your property.

This is done using an Ultra-Highly Accurate Faro Laser Camera which produces superior measurements than standard tape or laser measures.

Step 2:

Using these accurate measurements, our highly experienced architects will design highly detailed 2D Existing Drawings & Elevations of your property in its current layout.

Step 3:

You now have highly detailed and reliable Existing Drawings to produce concept drawings for your Change Of Use (Planning) Application. 

If needed, we’ll also have a call to iron out any concerns you may have.  

"My Architect designed a 6 Bed HMO Layout for my property without clear existing drawings and I was somewhat skeptic. I did a Pre-Planning application only to find out the Council needed highly detailed Existing and Concept Drawings. Kudos to Giovanni & Team for picking this up last minute and saving my life.

HMO Existing Drawings - Top Questions

What Are Existing Drawings?

Existing Drawings are a design blueprint of your property in its current layout and state.
They include all the known details, necessary to make any design changes to your property.

Why Do I Need Existing Drawings?

 You need Existing Drawings because, without them, it’s impossible to know how the property looks from a design point of view.
Any changes to layout, construction/renovation work or planning permission from the Council will require existing drawings.
They form the foundation of all future design updates and modifications.

What’s Covered In Existing Drawings?

 Existing Drawings Cover the following:
  • Highly Detailed Plans showing the layout of the property in its current state.
  • Front & Side Elevations

Note – Having done over 150+ HMO Projects, HMO Architect ensures the correct level of detail required by the Local Authority for Planning Applications. 


Is This A Paid Service?

 Yes, this is a paid service.

How Much Do The Existing Drawings Cost?

 Existing Drawings start from £900 (ex. VAT) and vary depending on the type and complexity of the property.

How Long Do The Existing Drawings Take?

 After The Measured Survey is done, our Architects can begin the Existing Drawings.
It typically takes around 8 working days to produce.
If you need it sooner you can request an expedited report within 4 working days for an extra fee of £300 (ex. VAT).

When Should I Get The Existing Drawings Done?


We always recommend getting existing drawings once you’ve purchased the property and are confident with your multiple occupation HMO Conversion Plans.

If you haven’t bought the property yet, HMO Architect highly recommends our HMO Design Appraisal Service where we help you evaluate the best design scheme based on the likelihood of Planning Success.


Do You Go On-Site To Do The Existing Drawings?

Yes, the Measured Survey which is carried out prior to the Existing Drawings includes a site visit.
The Existing Drawings themselves are done by our experienced architects in our creative design studios.

What Do I Need To Start The Existing Drawings? 

Well, to begin with, you need a property 🙂
Once you have this, we’ll need to book a Measured Survey where our Experienced Surveyor will do a site visit and collect highly accurate measurements using a Laser Camera.
The next step will be to send us all the existing drawings you got, even the Estate Agent Ones.
With this and the results of the Measured Survey, we’ll get to work in our studio and produce the Existing Drawings.

Very professional team and great architectural designs for my HMO. They also helped me get planning permission in a very difficult council keeping me updated throughout the process. Loved working with Ryan, Giovanni and the team. Highly recommend them for any architecture work across the country especially HMO and flat conversions.

I was very impressed with Giovanni at WindsorPatania he was friendly and help explain the project to me in a way I could understand. Being a first time investor I really felt he was more like a partner in my team then an architect.

Exceptional service at all stages of the process from Windsor&Patania. They created a vision of a beautiful home from an under-developed heritage property. They led us through a tricky planning and renovation process with care and attention to detail. And then they followed up with quality assurance and spotting as the project was implemented. And they did all of that with a smile and approachability that you can’t find elsewhere. Strongly recommend for anyone looking to build real quality into their project!

Fantastic team, really helpful and great communication! I had a challenging project that another architects could not solve but the team at HMO were able to redesign and get planning approved in 6 months from start. I also appreciated that the directors have been investing themselves. Thanks again, highly recommend the team! James
