Two storey extension- Bradley Stoke


The owners of this house in Bradley Stoke wanted to extend their existing bedroom spaces, but opportunity was tight because of the number of existing constraints.  As there was an existing conservatory to the rear, along with a sloping rear garden, and drainage limitations,  a side extension was required.  The area was relatively narrow- too narrow to create an entirely separate room, so the option to extend an existing bedroom was pursued. The existing single garage was set back substantially from the house, so we designed a new two storey extension which created additional garage space on the ground floor, while leaving enough driveway parking to satisfy the planning department. The existing third bedroom was extended out over this new space, and a new steel beam incorporated to create a larger bedroom space, with a generous en suite to the front.

ACHD designed and sought planning permission, Wessex Water consent and building regulations approvals. If you have a similar project in mind, get in touch!


Single Storey extension in South Glos

I’ve been looking forward to seeing this completed project, in South Glos. The project was for a single storey rear extension, which would open up the cramped kitchen and dining space into one big, spacious, comfortable kitchen, dining and family space. One of the owners runs her own business ( https://www.facebook.com/pg/Danderoar-Designs-296512510385430/about/?ref=page_internal) creating original, one off, hand painted keepsakes, and I knew her fantastic artistic eye and attention to detail would be put to use decorating and styling the extension… and I wasn’t disappointed!


The extension stretches across the back of the house, and enlarged a relatively small and cramped kitchen, and an under used dining room, into one large space. An existing conservatory was removed, so this new extension has not resulted in the loss of any garden space.

A large island in the kitchen creates a focal and social point to the house, and helps zone the large space.


Large bi folds open the room into the garden, and brings in light, as do three sizeable rooflights.

An existing recess has provided a comfortable snug space, with a perfectly sized corner sofa to fit it! The owners have used feature furniture and accessories to give personality and pops of colour, and large scale mirrors and artwork suit the large expanses of wall available.

ACHD designed and sought planning and building control permissions, and the extension was built to a high standard by local builder Edd Buckland, who has built three other extensions I have designed.

Garden room near a protected tree

img_6787.jpegThis extension, in Emersons Green, was designed to create a family garden room, adjoining the existing kitchen, and adjacent to the garage. The house itself is only a few years old, and was built near some protected trees. TPOs (tree protection orders) are applied to notable or historic trees, or where a tree or group of trees helps create or maintain the character of an area. Removing trees, doing work to trees, or building within the protection zone of a TPO means seeking additional consents from the council, and can be prohibitive.


Before- the TPO’d trees can be seen on the right hand side

The proposed location of this extension fell within the tree protection area of a TPO, and so the involvement of an Arboriculturalist was required. Our initial bid for planning permission was rejected, but a second attempt was successful. Key to this success was the involvement of the Arboriculturalist, a structural engineer and ACHD, to come up with, and negotiate a way of constructing the foundations of the extension so as to create minimal disturbance to the root system of the tree. The careful design involved building a ring beam from which to build the extension, avoiding the standard method of a deeper trench foundation. Investigations on site confirmed that this could be done without disturbing ground which had not been previously dug. South Glos planning approved the scheme, and building work commenced soon after!

The garden room is a gabled ended addition, fitting neatly to the existing garage roof. With large french doors, narrow slot feature windows in the side return give great views of the large garden, and along with rooflights, the space is light filled. Its proximity to the kitchen and dining area makes it the perfect play space, or area to relax.


Family room and Utility extension in Bromley Heath

I recently photographed a completed extension in Bromley Heath, for a family who wanted to extend their existing kitchen/diner to create a family space. The existing house had a small lean to, which was original, which housed an awkward utility space.




The roof line of the existing lean to was raised, and the remaining space infilled, and this gave space for a nicely proportioned seating/play space and a more practical utility space. A small WC was also incorporated. Large skylights help make it a bright space, even on a dark day


This project was built under permitted development, avoiding the need for a planning application, ACHD sought Building Control and Wessex Water consents, and the owners did much of the work themselves, which helped reduce the costs.


The neighbouring house also engaged me to design a very similar extension (which can be seen in the photo above), which I’m hoping to return to photograph soon!

Double Storey extension in North Somerset


The newly extended house

It’s been a while since I posted anything, it’s been a busy six months- but I’m hoping to catch up with several older projects to share here more frequently.

The first is a single and double storey extension in North Somerset. The owners had previously tried to get permission for a larger first floor extension, but this had been rejected by the planning department, twice, and once under appeal. The planning department objected to the proximity of the first floor extension to a neighbouring property, and the owners asked me to have a look a look at it and see what might be possible.



Through careful design and analysis of the limitations of the site, I was able to propose a large single storey ‘wrap around’ rear, side and front extension, creating a larger kitchen, diner and living space, along with a study/gym space, and a larger porch/entrance.

To the first floor, a double storey rear extension was designed to create a large master bedroom, and a modest side extension gave enough room for the owner’s to create an ensuite, which gave them everything they’d wanted from their original scheme, but in a format that would satisfy the planning department.

Kitchen in new side and rear extensions

The application sailed through planning, and I also sought Wessex Water and Building Control approvals. As you can see from the photos the house was in a very delipidated condition when the owners bought it, and they have worked tirelessly to renovate it into the modern, light, home it is now.

Bath Extension

I was invited to see a completed project in Bathwick, Bath, a couple of weeks ago and it was a delight to catch up with the owner and see the finished work. The house is a mid terrace Victorian property with a typical L shaped footprint, leaving a narrow gap between the kitchen and the boundary line.



I was tasked with designing an extension to fill in this gap, joining an existing adjacent extension and removing the existing small lean to extension to the rear, replacing it with a large lean to.

The extension has created a large open plan kitchen, dining and family space. The ceiling is high and plenty of roof lights flood the rear spaces with light. The structure which holds up the existing first floor helps zone the space, before large custom designed french doors spill out onto the garden space.

In addition to this room, the area previously used as a dining space has been reinstated to create a study/guest room. The window that once looked out onto the narrow side return has been retained, and a special glazed roof infill lets light down through.

The owners sourced a beautiful solid wooden kitchen from British Standard, and accessorised with great lighting, leather topped stools and an engineered oak floor.

Under the stairs we managed to squeeze in a shower room and WC, ensuring the extension is as practical as possible.


Kitchen Extension, Redland


ACHD designed and sought permissions for this single storey side extension in Bristol in 2015. The work has extended the existing small kitchen and also provided a ground floor WC and generous utility space.

New skylights add plenty of natural light, and a new rear access door for the kitchen and side access door for utility ensure the rooms are convenient. Using the existing wide side return area meant that this extension could be built without losing any usable garden space.
