Islington Architect for Period Homes and Extensions
Residential Architecture in Islington
Studio CMA is a residential architecture practice working across Islington, with a focus on period homes, thoughtful extensions, sensitive renovation, retrofit thinking and architectural interiors.
Based just over the borough boundary in Dalston, we’ve lived locally for almost 20 years and have worked on Islington homes for over 15 years, from Canonbury to Whitehall Park. That long-standing experience means we know how these buildings are put together, how light moves through them, where they tend to lose heat, and what matters when applying for planning permission.
Whether you are looking for an architect in Islington for a rear extension, loft conversion, retrofit, interior reworking or larger renovation, we help you make careful, well-judged decisions that feel right for your home, your street and the way you want to live.
Why Islington homes need careful architectural thinking
Islington’s homes are full of character, but many were not designed for the way families live today.
Victorian and Edwardian terraces can feel dark at the centre. Kitchens are often disconnected from the garden. Earlier rear additions may be cold, poorly insulated or awkwardly detailed. Storage can be limited. Bedrooms can overheat in summer or feel draughty in winter. In conservation areas, even modest changes to windows, roofs or rear extensions may need careful justification.
Many Islington homes are generous in character, but tight in usable space. A loft, rear room or basement can look promising, but the real work is making it feel generous, light and useful. That means thinking carefully about storage, daylight, circulation, head height, fire safety, structure and how one decision affects the rest of the house.
Good design starts by understanding these relationships.
An extension is not only about adding floor area. It affects light in the original rooms, how the home connects to the garden, how heat moves through the building and how daily routines work.
Retrofit is not just about adding insulation. It needs to consider moisture, ventilation, heating, airtightness and the condition of the existing fabric.
Interiors are not decoration added at the end. Kitchens, bathrooms, joinery, lighting and materials shape how the home feels and works every day.
Our role is to help you see these decisions together before the project moves too far in one direction.
Selected Islington projects
Over the past 15 years, we have worked on more than 20 Islington commissions, from loft conversions and rear extensions to whole-house refurbishments, interiors, retrofit-led upgrades, planning applications and early-stage appraisals.
That repeated local experience matters. Islington homes often bring together the same connected questions: how to improve light, layout, comfort and energy performance while working with solid-wall construction, conservation-area constraints, older rear additions and rooms that need to work harder for daily life.
The projects below are three selected examples with live project pages.
St Paul Street, Arlington Square Conservation Area
Victorian rear and basement extension with full internal reorganisation
A narrow Victorian home reworked from the inside out, combining a rear and basement extension with a clearer layout, improved circulation and early fabric upgrades.
The project shows how extension, retrofit thinking, planning constraints and budget decisions can work together to make an older Islington home calmer, clearer and easier to live in. The project page describes a rear and basement extension with full internal reorganisation in the Arlington Square Conservation Area, combining spatial reworking with early fabric and services upgrades.
Prebend Street, Arlington Square Conservation Area
Victorian terrace loft extension and phased whole-house reworking
A loft extension in a Victorian terrace that became a wider rethinking of how the house worked, from planning and fire safety to circulation, services and comfort.
The project shows how a focused brief can reveal connected decisions across the whole home, especially in a conservation area where roof alterations need careful judgement. The live project page confirms this began as a loft extension and evolved into a more holistic rethinking of the house within the Arlington Square Conservation Area.
Gladsmuir Road, Whitehall Park Conservation Area
Rear wraparound extension to reconnect a Victorian terrace with its garden
A rear extension to a Victorian terrace in Whitehall Park, designed to bring daylight into the kitchen and restore a natural connection with a north-facing, sloping garden.
The project shows how a careful extension can solve a spatial problem without feeling heavy or forced: improving light, levels, garden connection and everyday family life. The live project page confirms the house sits within the Whitehall Park Conservation Area and that the design was developed to improve daylight and reconnect the kitchen with the garden.
Beyond these featured projects, our Islington work has included loft conversions, rear extensions, basement extensions, internal alterations, joinery and interiors, planning applications, retrofit-led upgrades and whole-house refurbishment across homes in and around Canonbury, Barnsbury, Highbury, Arlington Square and Whitehall Park.
How We Work With You
Most of our clients come to us with a mix of ambition and uncertainty. They want more space, better comfort, or lower energy bills, but aren’t sure what’s possible or how to begin. That’s where we start. Our approach is clear, collaborative and tailored to homes like yours.
We begin by listening, understanding how you live now and what you want to change. From there, we explore design options, guide you through planning, and help you make confident decisions about budget, timing and materials. We bring technical rigour to retrofitting older buildings and a calm, detailed approach to delivering work on site.
Many Islington projects start with an Architect’s Home Visit & Appraisal. This is a structured, paid first step for homeowners who need to understand what is feasible, what constraints matter and which route is most sensible before committing to a fuller design process.
Whether you’re early in your thinking or ready to brief a builder, we help you move forward with clarity and confidence. We combine vision with delivery, always aiming to create homes that are brighter, warmer, quieter and more sustainable, with as little stress as possible along the way.
Retrofit thinking for Islington period homes
We specialise in upgrading London’s existing homes to be warmer, healthier and more efficient, without unnecessary disruption. As certified Passivhaus designers, we focus on breathable natural materials, smart ventilation and precision detailing that works with the building, not against it.
Many Islington homes are cold, draughty, solid-walled or affected by earlier alterations. Improving comfort and energy performance in these buildings needs care. Adding insulation changes how heat and moisture move through the fabric. Replacing windows can affect ventilation. Improving airtightness means fresh air needs to be planned properly. Heating upgrades work best when heat loss and the condition of the building have been understood first.
For retrofit-led projects, we can help you define the right route before committing to works.
If your project is still unclear, our Retrofit Strategy Service can help you understand options, risks, phasing and priorities.
If the retrofit direction is already defined, our Retrofit Architectural Services can help develop the design, coordinate the information and prepare the project for consultants, approvals or builders.

At Prebend Street, a compact roof extension became a calm bedroom suite, with storage, borrowed light and an ensuite carefully worked into the available space.
Architectural interiors for Islington homes
In many period homes, the success of a project depends on the details of daily life.
A kitchen needs to support cooking, storage, family life and light. A bathroom needs to feel calm, practical and durable. Joinery can make awkward spaces work harder. Lighting can make deep rooms feel softer and more usable. Materials affect atmosphere, maintenance, air quality and how the home ages.
We design architectural interiors as part of the wider architecture, not as decoration added at the end.
That might include kitchens, bathrooms, storage, joinery, lighting, colour, finishes and natural materials. The aim is to make the home feel coherent, practical and calm from room to room.
Planning in Islington’s Conservation Areas
Much of Islington falls within designated conservation areas, where even modest changes to windows, roofs or rear extensions can require careful justification. We have direct experience working in Canonbury, Arlington Square and Whitehall Park, and understand how to design for both heritage value and long-term performance.
Our early-stage planning research helps avoid costly missteps and dead-ends. We assess what’s achievable before design work begins, giving you a clearer understanding of the likely constraints before design work goes too far.
How to start an Islington project with Studio CMA

FAQs
-
Yes. We have worked on homes in and around Islington conservation areas including Arlington Square, Whitehall Park and Canonbury.
Conservation-area projects need careful early judgement because changes to windows, roofs, rear extensions and external fabric may need to respond to the character of the house and street.
-
Often, yes, but the right approach depends on the building, the type of insulation, the level of external change and how the home manages moisture and ventilation. In older Islington homes, insulation decisions should be considered alongside planning, fabric condition and long-term comfort.
-
Costs vary depending on the size of the home, the level of intervention, the condition of the building, planning constraints, materials, services and the quality of finish. Early strategic advice can help you understand whether your budget and ambitions are aligned before detailed design work begins.
-
A local architect should understand the kinds of homes, planning constraints and conservation-area sensitivities common in the area. Studio CMA brings long-standing Islington experience together with architectural design, retrofit thinking and interiors, helping you make decisions that are better suited to your home, street and long-term plans.
-
Yes. Many Islington projects involve both. A rear extension, loft conversion or renovation can be a good moment to think about comfort, insulation, ventilation, heating and energy use. We help you consider these decisions together, so the project improves how the home works as a whole.
-
Yes. Our Architectural Interiors service covers kitchens, bathrooms, joinery, storage, lighting, materials and room-by-room coherence. We design these elements as part of the wider architecture, so the home feels practical, calm and connected rather than pieced together at the end.
-
For a substantial renovation, extension, retrofit or conservation-area project, it is usually better to get architectural advice before asking builders to price the work. A clear brief, realistic scope and well-considered design help builders understand what they are pricing and reduce the risk of costly assumptions.
