Flat Conversion

Flat conversion planning consultants and architects helping you get the most from your property

We all know that there aren’t enough homes in the UK for its growing population.

One way to increase that number is by building – but that’s expensive and there’s always a battle over which land is suitable for people to live on. Another way is to divide houses up into flats, which helps more people have their own front door while increasing the earnings of landlords – a win all round.

As architects and planning consultants specialising in property conversions, we have helped dozens of landlords take advantage of the booming UK property sector to successfully convert their properties into multiple flats and significantly increase their wealth.

If you are serious about maximising your property’s potential, we can help you design your flat conversion to maximise the number of flats, the value of your property and your rental income.

As our client, we can oversee every stage of your flat conversion project, from planning permission and building regulations to contractor selection and construction inspection, and guide you every step of the way.

Flat Conversion Architects

Converting houses into flats is becoming increasingly popular. Since there is a high demand for flats in London and in other urban British areas, splitting a property into two or more flats will maximise both your rental income in the short-term, and profit on sale in the long-term. In other words, your flat conversion can add substantial value to your property and increase its rental yield.

For example, if you decide to sell, you will effectively have two or more properties to generate money from, not just one. Or if you decide to rent, you will generate a higher amount of rent with the more rentable properties that you have.

If you convert your house into two flats, you will generate almost two times more rent or if you convert your house into three flats, you will generate almost three times more than you would normally achieve.

But where do you start?

Although certain common building projects fall under ‘permitted development rights’ and do not require planning permission, you will require planning consent and building regulations approval for converting your house into flats. So, besides ensuring your contractors are converting your property on-time and on-budget, you will need to ensure you get the design right and comply with statutory requirements.

The wooden gate and brick building in the background emphasise the blend of modern amenities and traditional architecture. This image highlights the professional design and secure access features, key aspects of successful property conversions for increasing rental value and attracting quality tenants.

As architects and planning consultants specialising in converting properties, we can advise you on how to make the best use of your property and carry out the alterations to a high standard. We can also apply for flat conversion planning permission and building control on your behalf – providing you peace of mind through achieving compliance with planning and building regulations.

To get planning permission and comply with building regulations for flat conversion, your proposal should be acceptable in terms of layout and functional needs of the development; siting, massing and scale of new buildings; architectural style and materials; spatial and visual character of the surrounding area; landform and landscaping; privacy and amenity, including the avoidance of pollution; crime prevention measures; energy efficiency; and building regulations.

At Urbanist Architecture, we positively encourage conversions, provided that the buildings to be converted are suitable for that purpose and the conversion itself will not lead to harm. We believe that flat conversions, if done correctly, can contribute to urban regeneration and prevent pressure for housing on Green Belt sites.

The types of properties we work on for flat conversion include large detached houses, semi-detached houses or terraced houses that are located in sustainable locations and are no longer suitable for single-family occupation. As flat conversion architects, we have helped dozens of landlords take advantage of the booming UK property sector to successfully convert their properties into multiple flats and significantly increase their wealth. We can help you too.
