Harrow Architects

Scenario is defined less by a fixed visual style and more by how your project is understood, structured, and guided from the outset. We begin by looking closely at how you live and what your home needs to support over time, so the design grows from lived experience rather than from assumption or a preconceived aesthetic direction.

Our practice is also deliberately structured around specialist disciplines in creative design, technical development, and project leadership. That means your home is not only designed with ambition and care, but guided through every stage with clarity, rigour, and a level of oversight that helps protect the quality of the outcome.

Yes. We work across both the transformation of existing homes and the design of highly bespoke new-build houses. Our experience spans a wide range of house typologies across London and the Home Counties, including Victorian, Georgian, and Edwardian houses, terraced homes, locally listed and listed buildings, as well as highly sustainable new-build projects.

That breadth of experience means we understand the very different architectural, planning, and technical considerations each type of property brings. Whether you are reworking a historic home or creating something entirely new, we help you understand what is possible and shape a solution that feels coherent, intelligent, and specific to the way you want to live.

Yes. We offer a defined Pre-Purchase Service, giving you impartial expert advice before you commit to a property or move into a full design process.

This service can help you assess a property's potential, likely planning constraints, design opportunities, and the level of investment or complexity involved. The aim is to give you a more grounded understanding of risk, suitability, and long-term potential before major decisions are made.

Yes. Planning strategy is a central part of our early work because it shapes what is realistically possible on a site. We assess policy, context, site constraints, and the specific opportunities of the property before design direction becomes fixed, helping you move forward with a clearer understanding of what can be achieved.

We have an exceptional planning track record across historic homes, listed buildings, conservation areas, and other challenging planning conditions, as well as successful planning appeals. That experience allows us to combine ambitious design thinking with the strategic judgement needed to navigate complex approvals with clarity and confidence.

Every project is different, but as a guide, the design and pre-construction stages often take around 8 to 12 months. That timeframe can vary depending on the complexity of the brief, the planning pathway, the nature of the property, and the level of technical development required before construction begins.

The construction period then depends on numerous variables, including scale, procurement route, site conditions, and the complexity of the work involved. Throughout the process, your Project Director plays a key role in managing and communicating programme clearly, helping maintain momentum, improve efficiency, and ensure you always understand where things stand and what comes next.

Construction cost is managed from the outset, not treated as a one-off check later in the process. We keep a high-level overview of your budget from the earliest stages, helping align ambition, scope, and quality expectations before significant time or cost is committed. As the design develops, trade-offs are set out clearly so you can make informed decisions about where best to invest.

Your Project Director plays a central role in this. They help monitor cost movement, coordinate information across the wider team, and advise on how to maximise value from your budget based on nearly twenty years of professional experience in residential property. The aim is not simply to reduce cost, but to help you make balanced decisions that protect both design integrity and long-term lived value.

Yes. Not every project requires the full journey from first briefing through to construction, and we can support you at key strategic stages where that is most useful. This may include feasibility, pre-purchase advice, concept development, planning, or technical information up to tender.

These packages are offered on a fixed-fee basis for transparency, so you have a clear understanding of scope and cost from the outset. We can advise on the most appropriate level of involvement depending on what you need, whether that is early clarity before committing further or support in moving the project to a defined milestone.

Yes. Interior design is delivered in-house and forms part of one continuous design process rather than being treated as a separate layer. One of our designers is also a fully qualified and experienced interior designer, which allows interior thinking to be integrated seamlessly into the wider architectural process.

This means layout, materiality, lighting, storage, atmosphere, and furnishing direction can all be considered together rather than introduced later in isolation. The result is a home that feels more coherent and fully resolved, both in its overall spatial planning and in the details of everyday use.

Building or transforming a home involves significant financial commitment and a level of complexity that many people encounter only once. We help manage that risk by bringing structure, visibility, and experienced leadership to the process from the outset, so key decisions are grounded in feasibility rather than assumption.

Planning context, likely budget range, technical implications, and delivery strategy are all examined early, before major commitments are made. As the project progresses, dedicated project leadership remains in place to coordinate consultants, clarify decisions, and help you retain confidence, visibility, and control as complexity increases.

Our involvement becomes more active during construction, because this is the stage where decisions carry immediate and lasting consequence. We coordinate the wider team, review progress on site, assess changes as they arise, and work to protect the design intent throughout delivery.

This ongoing presence provides continuity when complexity increases. With your Project Director maintaining oversight of programme, budget, buildability, and decision-making, you have a clear point of leadership throughout the construction phase and a process that remains carefully managed through to completion.
