Single Storey extension, Bristol


This small single storey extension has been added to an end of terrace home in Bristol. A tiny kitchen and underused dining room have been turned into a large kitchen/diner/seating space with bifold doors leading to the garden. The owner, a keen cyclist, has also gained a Utility and bike store space, and a ground floor WC and shower room, perfect for coming in after a long cycle.

The owner chose a beautiful painted oak kitchen with quartz worktops, which looks smart and modern, and the peninsula with bar stools is perfect for being social.



Infill extension to a Victorian property

image1 (1)

Victorian terraced housing is often built with a main terrace, and semi detached ‘outrigger’ to the rear. This leaves a unused gap between the outriggers, and often makes the existing kitchen spaces dark, narrow and lacking accessibility to the garden. I’ve designed several ‘infill’ extensions to such properties, extending both sideways and into the garden.

This property was one example- A large kitchen diner now extends most of the width of the house, with bifolding doors. Steel beams are inserted to support the two storey section above, and a lean to roof with roof lights brings light and height to the space.

A small WC has been added, and the original window into the second reception room opened up to leave a free flowing home.

The owners have also built lovely wide, shallow steps, leading from the bifolding doors down into the garden level.

Single storey extension- Bath


This single storey, Bath stone rear and side extension replaced an old garage, and small flat roofed extension, creating a beautifully finished kitchen/diner, new attached garage and shower room.




The extension is finished in Bath stone, matching the original detailing, but with a modern flat roof, allowing for brilliant ceiling height throughout. A rooflight floods the extension with light.

Internally a lovely U shaped kitchen has been created, with a peninsula and a high bank of storage, which leads to a dining/seating space. The prefab detached garage has been replaced with a new attached store, and in addition the owners now have a small ground floor WC and showeroom.

Merry Christmas!

Merry Christmas and Happy New Year to all my customers, past and present!

And to any future customers- If your Christmas dinner table is going to be as tightly packed as this tomorrow, maybe its time to consider an extension…!



My house


While I’ve helped hundreds of people design extensions to their homes, I’ve never designed one for myself. We might not have created the biggest extension, but I can now join my customers in having lived through the mess, noise and dust!



With a terraced house, on a hill, our options for development weren’t huge- but we really wanted to stay in a home we like, have put lots of work into, and feel very comfortable in.  While the usual place to add space is to the rear, because we lacked rear access, have a terraced garden, and a well loved and used patio accessed directly from the living room and dining space, we’ve never been keen on this option. We wanted to add space where it was most needed. Our kitchen was proportionately large, we had a comfortable dining space and we already had a small spare bedroom, but our hallway was very tight, and the living room area lacked enough seating for larger family gatherings.

An idea to add a porch developed into a shallow single storey extension across the whole frontage, replacing an ‘of its time’ cast concrete flat roofed canopy, and also providing a large store for our home appliances.


Extending the front of a house isn’t always the easiest, but the planning application was granted, and work commenced in the early spring… with a few pauses for the arctic march we experienced!


The extension is a lean to, with a gable fronted section over the front door, and the vaulted ceiling inside adds height and drama to a hallway which has trebled in size. Making a bigger hall isn’t everyone’s top priority, but a hallway needs to be practical and flowing- there’s nothing worse than trying to usher small children, bags, coats and prams etc through a front door, when the weather is terrible outside, into a tiny and tight hall. The house works much better with this increased circulation space.

The living room has also benefited from the increase in size, with enough room for an additional sofa. The corner windows are a lovely feature and capture light from two aspects. Somehow the extended living room is more than the sum of its parts- everyone comments how much larger it feels. Built in cupboards and shelving have also helped make this space feel less cluttered, and provide plenty of storage for media devices, DVDs, books and other items. Our carpentry was carried out by Jamie at JH Carpentry  (who also fitted our kitchen several years ago) and he did a fantastic job, making the bookcase in the angled roof profile quite a feature of the room.

In addition, the original patio doors were removed, the opening widened, and new bifold doors added- just in time for the long hot summer we enjoyed. Our garden is well loved and while it’s a cliche, in the summer the patio is an extra room, having a bigger, better view of it, and a more natural flow into it, has been a great asset.

In addition, the hall, stairs and landing were re-plastered, redecorated, and Jamie created a lovely window seat into an unused area. The living/dining space was fully redecorated, and the front garden remodelled, with indian sandstone patio, rendered walls and feature lighting.

Its not always easy living through an extension project, from day one we had to access the house through the works, and at one stage accessed the front door via a step ladder (which my 7 yr old thought the greatest fun!), widening two openings, and removing a solid concrete canopy generated A LOT of dust. In total we only added 10 sqm of new space, but it has made a huge difference to how the house feels, and how we live in it. I am a big fan of adding well functioning, efficient, spaces, where you need them!

Horfield kitchen/diner extension

This single storey extension replaced an existing coal shed and outside WC, and an ageing overhanging roof structure, and involved removing the wall between the original, small, kitchen and dining rooms, to create one larger open plan kitchen and dining space.


The bifold doors and large flat roof window flood the room with light, and the owners have installed a beautiful herringbone timber floor, modern kitchen, and also created a seating space. A small utility and ground floor WC complete the development, and turn a tired and old fashioned 1930’s layout into a bright and open space for a modern family.

ACHD worked with the owners to design the extension, and sought planning and building control approvals.

Single Storey extension- South Glos

DSC02027This lovely single storey extension in Downend is one of a matching pair- I designed the neighbouring extension a few months prior to this . I went back to see it completed today, the owners have created a light filled seating space, adjoining their existing kitchen/diner, looking out onto their garden. The extensions look super smart together, with matching detailing and materials. It’s interesting to compare the layouts- the neighbouring extension created a large open plan kitchen/diner and family space, along with a WC and utility, also knocking their original dining room into the space, while this extension has retained a separate, adjoining, reception room, and created an L shaped kitchen- diner and seating area, showing just two of the options there are, for a relatively modest sized extension.
