As the increasing demand for housing in the UK continues to outstrip supply, many landlords, investors, and property owners are choosing to convert their buildings into flats.

Flat conversions are becoming a popular solution – converting a single-use building into multiple residential units helps owners to increase value, while also helping renters or first-time buyers to find new properties that suit their needs.

Though converting a property into apartments can be complex, depending on the building’s original use and design, it can be more cost-effective to renovate an existing structure than to demolish it and construct an entirely new building.

Of course, converting flats takes a lot of planning. From transforming the current layout into several functional dwellings to calculating where walls can be added or removed, you’ll need architects and structural engineers to advise you – which is where RD Engineering can step in to ensure the successful completion of your flat conversion project.

House to Flat Conversions

Adapting a property to accommodate multiple homes is common in built-up areas like busy towns and cities, where small families, couples, young professionals, and students are all likely to be looking for suitable places to live.

There are many different types of buildings that can be divided into flats, including large detached or semi-detached houses, vacant spaces above shops, or other non-residential spaces that comply with Local Planning Authority policies for flat conversions.

Properties may be partially converted, such as a top floor flat conversion or studio flat conversion, or fully converted to flats for private renting or student accommodation. In some cases, they can also be changed from flats back to single-use in a deconversion.

Whichever route you want to take, it is essential that all potential issues are addressed and the project is carefully planned in advance, so that the job can be completed well.

This includes meeting the minimum square footage required for individual flats, incorporating all necessary amenities such as plumbing, heating, and electricity, and ensuring separate bathrooms, private access, and potentially parking facilities for each flat.

Since the layout is limited by the original building floorplan, there is no standardised design to fall back on. A qualified architect must create a bespoke design in consultation with a trained structural engineer, overseeing the feasibility, proposals, surveys, and trade work standards.

Flat Conversion Design

Most projects that separate larger dwellings into multiple smaller dwellings will require an application for full planning permission from the local authorities. If it’s an older listed building, you would also need consent to convert the property into flats or change the number of apartments in the building.

Unlike house to flat conversions, this may not be necessary for converting non-residential properties to flats. Though approval from the local council is still required, commercial to residential conversions can often be carried out under permitted development rights without needing full planning permission.

However, with more safety concerns, many councils are rejecting proposals that do not strictly meet every required policy. Failure to meet these standards from the start could lead to expensive fines, retrospective work, or even requests for demolition.

To gain not just planning permission but also approval from Building Control, you must provide technical drawings and construction information with your application, showing compliance with local planning policies and national building regulations.

To ensure the flats will be fit for purpose and safe for habitation, you must consider everything from structural integrity and insulation to ventilation and fire safety adaptations.
