Individually Tailored Homes

We are an award-winning architectural micro-practice specialising in residential projects, including newbuild, reconstruction and significant refurb / extension / transformation of existing. We are currently involved in a small number of projects with construction values ranging from €350,000 up to €1.5m.

The majority of our projects will end up as highly efficient A-rated homes for life.

We have a track record in delivering highly bespoke projects which run smoothly through design, planning and construction stages, many of which have received awards and been widely published.

We use highly detailed 3D Digital models to plan, visualise and clearly communicate from early in the design process to ensure a successful outcome.

Double extension to 1930s house


“Red Wonder....

The best-loved spaces are rarely just austere, minimalist and perfectionist creations. They are busy, improvised and personal. This is clearly accommodated in David Flynn Architects' design”

Warm red-brick gives character to the front of this Arts-and-Crafts style house and this became the design driver for a double height extension to side and rear.


House rebuild and transformation


“The team delivered in designing the home of our dreams.”

Client comments

A simple modernist material palette transforms a detached 1960s house into a timeless family home. By extending out to the side and rear, large open spaces are formed overlooking the mature rear garden.


Transformation and Extension


Reconstruction of a large three-storey house in a conservation area

Calculated BER: A3
56.04 kWh/m2/yr
10.9 kgC02/m2/yr


This mid-20th century dwelling forms half of a pair of distinct houses in Malahide. This house exhibits a number of fine features which contribute to the special character of the street, but internally the layout is an array of small rooms with winding corridors.

These details are to be retained and the quality and style of the street preserved while the interior rooms are reconfigured into large, bright spaces.
This new layout combines the flow and openness of open- plan with private break-out spaces, ideal for a growing family. Relocating the staircase, allows the new covered porch and hall door to be centred on the impressive front gable elevation, instead of hidden off to the side.
This provides long views through the entrance hall and living space directly out to the mature garden. At the rear, the existing flat roofed extension to the rear is to be rebuilt with a higher ceiling.
Floor-to-ceiling glazed sliders flood the living spaces with evening light, while a high level window and large rooflight capture the first morning rays ensuring the interior is bright throughout the day.

Completed Spring 2023

Dormer bungalow rebuild


“Behind the unassuming facade of this semi-detached bungalow in Terenure lies a light-filled oasis ideal for modern family life.”

“Sensitive, simple, understated design.”

Jury Commentary

Project Award

A modern home is rebuilt behind the front gable of an existing dormer bungalow. To the rear, the North-facing elevation is enlivened with a dramatic glazed screen which sweeps out to catch afternoon sun.


Pavilion extension to Victorian house


“Real architectural intelligence at work”

AAI Awards commentary

“It's an emblem of the new century, but with a delicacy that respects the old house.”

Project Award

A contemporary extension is added onto a fine Victorian house in Sandymount, Dublin.
The new room aims to emulate the scale and grandeur of the original drawing room to the front of the house for everyday use.


Refurbished and reconfigured 1970s bungalow


A 1960s semi-d in Sandymount is refurbished and extended with a new two-storey addition to the rear. At ground floor level, an offset in the plan allows Southlight to reach the back of the house.


Brick Extension to 1960s House


“Full of light and warm details. A series of roof lights, interspersed with sculpted plaster curves, also allows light and shadows to move through the space during the day, creating beautiful effects.'

Project Award

“Thoughtful and clever use of natural light.”

Awards jury commentary

A 1960s semi-d in Sandymount is refurbished and extended with a new two-storey addition to the rear. At ground floor level, an offset in the plan allows Southlight to reach the back of the house.


Large kitchen extension


“...work brimming with intelligence, ingenuity, judgement and taste.”

AAI Awards

“Stylish functionality”

“David was a pleasure to work with...we were absolutely delighted with how things turned out”

Client comments

Project Award

A typical north-facing 1960’s semi-D is refurbished and extended. With a North-facing rear orientation, carefully positioned light wells were introduced to draw sunshine into the new family spaces.


Portico extension


“Inside the extension, the white brick creates a bright space of timeless modernist character.”

“David brought us a very unique design which we absolutely love.”

Client comments

Project Award

With a wedge-shaped corner site, this house was refurbished and re-orientated to create privacy and take advantage of a perfect Southerly location. A tall white-brick portico shades the interior.


Art Deco House renovation


“The new layout flows in a beautifully simple way that appears effortless but takes a lot of work to get right.”

“With great attention to detail, both original and new features have been blended seamlessly. Beautifully refurbished, and would make a lovely family home”

An unusual Art-Deco era house from 1938 is refurbished and extended to provide a modern home. The front of the house was reconstructed with a new porch, entrance area and raised planter which are sympathetic to the period.


1930s house rebuild

Harold's Cross

“The final result is stunning, as well as being a comfortable, bright and warm living space.”

Client comments

Project Award

“Worthy for commendation for remaining true to the original house in its detailing.”

Jury Commentary

Red, bull-nosed bricks were an unusual feature we found in this 1930s Art Deco house and became a design cue in rebuilding the house with extra bedrooms, bathrooms, storage, and living space.


Bungalow rebuild


New house in a Woodland setting

Lying in a slight hollow on a one acre site of mature woodland, the structural shell of an existing bungalow dating from the 1970s is planned to be incorporated into a new house.

Lying in a slight hollow on a one acre site of mature woodland, the structural shell of an existing bungalow dating from the 1970s is planned to be incorporated into a new house.

A series of new gables will articulate the roofscape and create additional accommodation upstairs as well as dramatic double-height spaces below.

The principal living spaces have been laid out to track the movement of the sun from morning to evening, and provide a series of graceful spaces for family living and entertaining.

The new high performance thermal envelope creates a home performing to contemporary standards whilst reusing an old structure to minimise embodied carbon.

Period house extension

Park Avenue

Creating everyday living spaces in a Victorian house

Built in the 1860s, this brick-fronted home features beautiful original reception rooms and an elegant stairwell but lacks the basics of a contemporary family home.

Extending to the side and rear, additional accommodation will provide kitchen and living spaces, a home office, children’s play area and ancillary requirements like utility, pantry, plant room. Within the original building new ensuites and wardrobes will be sensitively inserted.

With a very long floor plan, a large new lightwell is included between the original rear reception room and new living areas so that daylight continues to spill into the original house.

In three piered bays, the new garden elevation has a deep porch to shade the extra-tall glazing overlooking the garden.

Planning Permission granted. Tender stage

Transformation of a mid-century house


An existing house will be significantly extended to the side and rear, with a new front entrance elevation and dramatic two-storey garden façade. South-facing, the garden elevation features deeply incised glazing to maximise sunlight without overheating.

An asymmetric pitched roof sits over the master bedroom which has a dramatic pitched ceiling underneath, and large monocular window overlooking the garden.

An asymmetric pitched roof sits over the master bedroom which has a dramatic pitched ceiling underneath, and large monocular window overlooking the garden.

Organised around a new toplit stair hall, an efficient layout creates a seamless enlargement of the original house, and increased ground floor ceiling height in the main living spaces.

With a new high performance thermal envelope, the new house is expected to achieve a BER ‘A’ rating.

Planning permission granted. Construction due for Completion Spring 2024

House reconstruction and extension


Extending a house to fill a sunny double-width site

This unusual mid-century house is wide and shallow with a wide redundant garage to the side and a very sunny outlook to the rear. The reconstruction will incorporate much of the original fabric into a significantly enlarged house which is being pushed out to front, side and rear, as well as up into the attic.

A new two-storey extension wraps around the house and has been sensitively designed to tie into the original roof structure to create a coherent whole.

The new front elevation has been designed around a new entrance porch area with a stepped floorplan to mirror the steps leading up to the door.

To the rear a new porticoed elevation steps up with a taller ceiling and extensive, shaded glazing overlooking a sunny back garden.

Planning Permission granted. Construction commencing in 2023.
