HMO conversion builders in North London

We convert and refurbish houses as HMOs across North London, from a four-bedroom refurbishment in Tottenham to a 28-bedroom conversion in West Hampstead. Design, structural work, services and fit-out are handled by one team.

What we do

HMO conversions and refurbishments

An HMO conversion has to fit more bedrooms and bathrooms into an existing building, often while extending it or adding floors. That usually means structural alterations, new drainage and utilities, and careful planning of service routes.

We convert houses into HMOs, extend them to add rooms and refurbish existing HMOs. We can build to your architect’s design or take on the project as design and build contractor, and we agree our responsibilities in writing before work starts.

01

Feasibility and layout

We review the building, your brief and the number of rooms you are aiming for, and identify the structural and services work involved.

02

Structure and extensions

Underpinning, steelwork, extra floors and extensions, coordinated with your structural engineer and built around any period features being kept.

03

Drainage, utilities and services

New drainage, utility connections and service routes for the extra bathrooms and kitchens, planned before the internal layout is fixed.

04

Fit-out and handover

Bedrooms, bathrooms, shared kitchens and living spaces fitted out and handed over with the information the owner needs.

HMO licensing and planning requirements are set by each council. Your architect or planning consultant advises on them, and we build to the approved design.

HMO conversion FAQs

Need advice on your property? Talk to the JBP team.

Where do you work?

We are based in St Albans and work across Hertfordshire, Bedfordshire and North London. Our HMO projects include West Hampstead, Maida Vale, Tottenham and Tooting.

Can you add rooms by extending or adding floors?

Yes. At Greencroft Gardens we underpinned the building, added steelwork and built two extra floors to reach 28 bedrooms. Whether that is possible on your property depends on the structure, planning permission and budget.

Do you refurbish existing HMOs?

Yes. At Maida Vale we refurbished a 10-bedroom HMO and gained an extra bedroom and three bathrooms by reworking the layout.

How long does an HMO conversion take?

Our HMO projects have taken between 16 and 39 weeks, depending on the size and the amount of structural work. We give you a programme once the scope is agreed.

Can you work with our architect?

Yes. We can build to your architect’s design or take on design and build responsibility. We agree who is responsible for what before work starts.
