The same rigour and attention to detail that defines our residential work extends across every commercial commission we undertake.

The practice has particular depth of experience in gallery and cultural spaces, hospitality, and workplace design - and a strong track record of working with some of London's most distinguished estates, including the Bedford Estate and the Sir Richard Sutton Estate. These relationships, built on trust and a thorough understanding of each estate's character and requirements, speak to the kind of practice we are.

We have delivered a wide range of commercial projects across London, from boutique restaurants and cafés to hotels, offices, and mixed-use developments. We also undertake feasibility studies for commercial and development schemes, providing the clarity and confidence needed to take a project forward.

Whatever the brief, clients receive the same level of personalised service and design-led thinking that the practice is known for - a single studio, fully committed, from first concept to completed building.

Before committing to a project, it pays to understand what is genuinely possible.

A feasibility study with Johanna Molineus Architects gives you a clear, authoritative picture of your site or building's potential - exploring what planning policy will permit, what the constraints are, and what a scheme might realistically look like and cost. It is an invaluable first step, whether you are considering a purchase, assessing development potential, or trying to establish the right scope for a project before appointing a full design team.

We bring to this work the same expertise that underpins everything we do: deep knowledge of the London planning system, conservation experience where listed buildings or heritage assets are involved, and the design intelligence to see possibilities that others might miss.

A feasibility study can be commissioned entirely independently of any further appointment - though many clients find it the natural starting point for a longer working relationship.

Planning is rarely straightforward - and navigating it well requires more than a working knowledge of policy. It requires relationships, experience, and the ability to make a compelling case.

Johanna Molineus Architects has spent more than two decades working across London's most complex planning environments, building strong working relationships with local authorities, conservation officers, and heritage bodies. We understand how decisions are made, what matters to each stakeholder, and how to present a scheme in the way most likely to succeed.

Our planning expertise spans the full range of residential and commercial applications - from householder extensions in conservation areas to listed building consent, major development schemes, and prior approval applications. We are experienced in the particular requirements of London's great estates and have a strong record of achieving consent where the constraints are considerable.

Design and planning are inseparable in our approach. We do not design first and then attempt to fit the planning system around it - we understand policy deeply enough to use it creatively, finding solutions that satisfy the local authority while remaining true to the design intent.

Where planning permission has been refused or is proving difficult to secure, we are equally experienced in appeals, pre-application discussions, and resubmissions - and we know when each approach is likely to serve a client best.

Interior Design

Architecture and interior design are not separate disciplines — they are two halves of the same conversation, and we treat them as such from the very first sketch.

Every project we undertake is considered in the round: how light moves through a space, how rooms connect and flow, how materials and finishes work together, and how a home or building will feel to live and work in day to day. That interior sensibility is embedded in our architectural process, not added at the end.

For clients who would like interior design support alongside their architectural project, we are able to assist with spatial planning, material selection, and the considered detailing that brings a scheme together. Where a full interior design service is needed — including furniture, fixtures, and equipment specification, procurement, and styling — we work closely with our sister practice Studio Materi, whose expertise in this area is the natural complement to our own.

Engaging Studio Materi from the outset, alongside Johanna Molineus Architects, means that architecture and interiors are developed together — with joined-up thinking between architect and interior designer from day one. The result is a home that is not only beautifully designed, but entirely cohesive from the structure to the last detail.

Architecture is a universal language — but working successfully across borders requires fluency in the planning systems, building regulations, and professional cultures of each country, as well as the relationships and registrations to operate within them.

Johanna Molineus Architects is well placed to work internationally. The practice was founded by Johanna Molineus, whose career was shaped by years working in Tokyo, Berlin, and Paris before establishing the London studio in 2002. Johanna is registered as an architect in the UK, Germany, and France, and between the team we speak English, French, German, Polish, and Portuguese — meaning we are able to work directly and fluently with many of our international clients in their own language.

We collaborate with trusted local professionals in each territory to ensure every project meets local requirements while maintaining the same standard of care and design integrity our London clients expect.

If you have a project outside the UK, we would be delighted to hear from you.

Some of the most rewarding architecture happens within existing buildings — where the constraints of history, fabric, and planning become the creative starting point rather than the obstacle.

Johanna Molineus Architects has extensive experience in the renovation, restoration, and sensitive adaptation of historic and listed buildings, and a strong record of achieving listed building consent and conservation area approvals. We understand what heritage officers and conservation bodies are looking for, and how to make a case that satisfies their requirements while realising a client's ambitions in full.

The same care and ingenuity we bring to heritage work extends to all renovation projects — whether listed or not. Every existing building has a character worth understanding before anything is changed, and that understanding shapes everything that follows.

Seeing a space before it is built changes everything.

Immerse is an interactive walkthrough service that uses gaming technology to place you inside your future home or building before construction begins. Unlike a static visualisation, Immerse is fully interactive — move through the rooms, adjust the lighting, change paint colours, swap furniture, and experience the space at different times of day. It transforms abstract drawings into a lived, felt experience, and gives you the confidence to make decisions that are right for you.

Immerse is offered as an optional addition to our architectural service, and is equally powerful for residential and commercial projects. It is particularly valuable at key design stages, when choices about materials, finishes, and layout have the greatest impact on the final outcome.
