Make the most of today's rental demand with HMO Conversions.
With the rising rents and the more people looking for shared housing, HMO conversions have become a smart choice for landlords and property owners. By turning your property into a house in multiple occupations, you can increase your income and make better use of your space.
At Paramountbuilt, our HMO conversion specialists take care of everything, from planning and designing to building and legal checks, so that you can get a fully approved, high-earning rental property without the hassle.

Types of property suitable for HMO Conversion

Terraced houses
Terraced homes often offer the right layout and size for multiple bedrooms, making them a budget-friendly option for small to mid-sized HMO conversions.

Semi-detached homes
For more space and easier access for extensions, semi-detached houses are ideal for creating extra bedrooms, en-suites, or shared living areas in an HMO.

Detached properties
A perfect option for large scale HMOs as it allows more design freedom, and typically avoids noise complaints due to distance from the neighbouring properties.

Flats above shops
Often, underused flats above commercial units can be turned into compact HMOs, especially in busy urban areas with strong rental demands from working professionals.

Large family homes
Older family houses with multiple rooms and generous floor plans are ideal for conversion into spacious and comfortable houses for multiple occupations.

Commercial to residential conversions
Converting old offices or retail spaces into residential HMO units is becoming more common, offering investors great flexibility and often bypassing full planning permission.

Testimonials
Paramountbuilt 36 Google reviews Elvin Turner2025-05-23 Great consultation! Lielis Andrews2025-05-23 Quick and efficient service. Would use again. Timely visit to property and survey provided within 5 working days. Excellent communication from start to finish. SALINDER PATEL2025-05-23 Great service, did everything they could to ensure i got this within the timeline. Customer service was 5 stars, kept me updated all through the process. Definitely be using them again. Deborah Dunkley2025-05-21 I chose this company after reading their trust pilot reviews. Initially I spoke to Amber who was very knowledgeable on the telephone and was able to speak to me in technical terms which was reassuring. A survey was arranged and carried out for the approaching weekend. Aslan carried out my Survey and he was thorough. I have now instructed them to go ahead and submit my plans for building regs and I know my project is in good hands. Yasemin A2025-05-09 I recently used paramountbuilt for a structural survey on a property I was purchasing, and I couldn’t be happier with their service. From start to finish, the team was professional and thorough. They provided a detailed report that was easy to understand, highlighting all the key findings and offering clear recommendations. Their expertise and attention to detail gave me complete peace of mind during the buying process. Valentina Ljubchinskaja2025-05-08 I applied for a house extension with Paramaunt Build and submitted a planning permission application through the council. At the start, Sophie and Zoe were very nice and helpful. Later, Sumet came on board and did a great job with the painting. I had a few amendments, including some that came after the application had already been submitted, but the team was always accommodating and made the changes as requested — they were truly kind and supportive throughout. Amber helped speed up the process, and I was told that hopefully by 8th May, the council would approve the project. And today, on 8th May, Amber called with the great news — my application has been approved! Right now, we're halfway through the process with the company, and the next steps will be with the building control department. I hope that part goes just as smoothly and efficiently. Once the whole project is completed, I’ll be happy to leave a detailed review. Thank you, Paramaunt Build team!
FAQ’S
If you intend to convert the property into a large HMO (accommodating seven or more occupants) or in zones with an Article 4 Direction, you might need planning permission for an HMO conversion. Article 4 areas have more restrictions – check with your local council.
The typical period to complete an HMO conversion is between 8 to 12 weeks, although it may vary according to the property’s size, amount of work, and other planning or licensing approvals needed. Good organisation could streamline the process.

These additional schemes apply to smaller HMOs that were previously unregulated.
There are specific legal, safety, and space guidelines that you need to follow if you wish to convert a property to an HMO. You may also need to obtain a planning permission or a licence.
