Around an ongoing barn conversion project, this website draws together advice, information and references to aid all would-be and current barn and non-residential building converters and renovators.

Our approach takes on board 'healthy house', sustainable, ecological & environmental concepts to as great a degree as timescales and budgets allow.

That's a bit of a 'how long is a piece of string' question miss dee ennis and obviously depends on location, the approach you take to the project (architect / main contractor / self-managed with sub-contractors etc.

Design Patterns ~ my choices

November 29th, 2007 by mbc

I’ve already written about one of my favourite building design books – ‘A Pattern Language - Towns Buildings Construction’ by Alexander, Ishikawa & Silverstein. I thought it would be worthwhile stating which of the patterns I’ll be paying most attention to in my design. The list is not exhaustive, other patterns will have a bearing, new patterns will come along, chosen patterns will fall by the wayside. But here are my main current choices:

106 Positive outdoor space.
A complex pattern, but generally - give outdoor space a distinct and definite purpose, make spaces entities.

112 Entrance transition.
Provide a graceful transition between the outside and the inside.

125 Stair seats.
Seats on stairs provide a vantage point, but don’t remove the sitter from the action.

126 Something roughly in the middle.
A pattern to apply when designing the outdoor space, especially the yard between the two barns.

128 Indoor sunlight.
Maximise the number and size of windows thereby maximising the indoor sunlight.

133 Staircase as a stage.
A flared bottom step gives the stairs a function that may otherwise be overlooked. See also 125.

142 Sequence of sitting spaces.
Vary sitting opportunities through the range of rooms and spaces in the building.

145 Bulk storage.
Around 15-20% of the volume of the building should be given over to bulk storage. This can sensibly be designed with reference to pattern 162 North Face.

161 Sunny place.
Maximise the use of the space to the south of the building in the angle between the wall and the ground.

163 Outdoor room.
Build an enclosed outdoor room with trellis’s, hedges, columns and trees, that is open to the sky.

168 Connection to the earth.
Make the interface between the building and the earth as ambiguous as possible through clever design of steps, paths and terraces.

170 Fruit trees.
Applicable in various places, but again especially the yard between the two barns.

171 Tree places.
Plant trees to form distinct places, ensure empathy between the trees and the surrounding buildings.

175 Green house.

176 Garden seat.

178 Compost.

180 Window place.
Provide seating to sit in or before windows.

181 The fire.
The true heart of any home.

182 Eating atmosphere.
Have a large table in a pool of light.

185 Sitting circle.
Create a sitting place where the inhabitants can face each other and that is not cut through by a corridor. Provide plenty of comfortable seating.

204 Secret place.
Every home needs a secret place!

Construction Patterns
As the base structure of the building is already established, I am employing a minimal number of construction patterns.

229 Duct space.
Cables and wiring are always a pain – best to preplan for them and keep them out of the way and out of sight wherever possible.

230 Radiant heat.

232 Roof caps.
Ornament the roofline.

237 Solid doors with glass.

238 Filtered light.
Light that passes through leaves or stained glass is magical…

241 Seat spots.
Choose seating spots carefully for sunlight or shade and the view.

242 Front door bench.

245 Raised flowers.
Use raised beds to protect flowers from heavy feet and bring flowers closer to their admirers.

246 Climbing plants.
Blend the building and the plants.

We have stalactites in our walls! on December 23rd, 2007
Rather strangely, I've we've discovered stalactites in our walls.

Big Metal Shed on July 16th, 2007
I've been at the barn for a few days, digging holes, hitting things with hammers & lugging things around with a wheelbarrow - my builder competency level is somewhere around that of navvy.

Rest and Recuperation on September 25th, 2007
Firstly, I must apologise for the infrequency of my recent posting.

Going Green on March 11th, 2007
We never really had any great green aspirations when we started out on this project.

Lime Analysis on May 5th, 2007
Inspired to analyse the composition of my mortar, I improvised and placed a lump of mortar that I'd levered out of my wall in the strongest acid I could lay my hands on - white wine vinegar 8% acidity.

Building Progress ~ November 2007, week 1 and 2

November 22nd, 2007 by mbc

Let the games begin.

exterior excavations
The first phase of building involves excavation of the exterior ground levels all around the building to provide drainage trenches and ensure that exterior floor levels are below the eventual interior floor level.

Internally, the existing flag stone, cobble and concrete floors have been removed and dug out down to the level necessary for the installation of the new floor.
internal barn floor begins

Hardcore has been placed in the main barn and compacted as the beginnings of the new floor.

The wooden first floor in the kitchen end of the barn has been removed.

sewage trench across the yard
sewage system
Trenches have been cut along the back of the building and across the yard, complete with pipework to carry waste to the green clean-water sewage system (of which more shortly) that has been installed in the nearby field.

Rock ‘n’ Roll on April 7th, 2007
Today’s job was clearing our fine collection of rocks to one side of the yard.

Building Progress ~ February 2008, week 1 on February 14th, 2008
The true proportions and dimensions of the final building are now beginning to appear.

Meet the architect on July 19th, 2006
I've always fancied the idea of engaging an architect (if I'm honest, inspired by Kevin Mc of TV fame), so I went to speak to one today.

Gas Pipeline Woes on June 23rd, 2007
A rainbow rose over the pipeline today! I must admit I loathe the thing.

Pointing (is rude?) on April 26th, 2007
I'm going on a course tomorrow to learn the basics of using lime, with a view to working on the pointing of the stonework at the barn myself.

Le Corbusier ~ The function of a house

November 18th, 2007 by mbc

The functions of a house, setting aside all other ‘romantic cobwebs’ are to provide:


1. A shelter against heat, cold, rain, thieves and the inquisitive.
2. A receptacle for sun and light.
3. A certain number of cells appropriated for cooking, work and personal life.

Le Corbusier … keeping it simple.

Seven Lamps of Architecture on June 20th, 2007
I was recently wandering around the web rooting through building and design related sites and came across a reference to John Ruskin's Seven Lamps of Architecture intrigued by the title, I decided to do some more digging and came across one of the foundations of architecture over the last 150 years.

Green = Mean ?

November 12th, 2007 by mbc

I’ve spent the day practicing my version of precision carpentry cladding openings of my big metal shed. My approach to carpentry is based on one of the many mantra’s of someone of great wisdom who used to work with my father and brother:

Measure twice, cut once.
I have finely tuned this to:
Measure once, cut once. (It’ll […]

I’m certainly no bathroom designer / the strange 1 metre wide space

November 8th, 2007 by mbc

The original plans for the barn had two largish bathrooms one of which contained an airing cupboard that to my mind was a waste of space. Not being a person who knows when to stop meddling, I decided to remove the airing cupboard, add an ante-room to the main bedroom’s en-suite and move one of […]

New Pictures ~ Before

November 6th, 2007 by mbc

I’ve been promising these for a while, but eventually I’ve got there.
I’d added a whole new set of photographs of the barn to the site that I’ll use as my before photo’s. Hopefully, I can use these to demonstrate progress as the conversion goes on. Some of them are similar to other pictures I’ve taken […]

Attention to detail…

November 4th, 2007 by mbc

So, as we have started work, we need to think about all those details that I’ve put to one side until we had a builder.
Not liking getting too formal about such things, it seems like a good idea to make a list so:
Last update [4th November 2007]

Ground or Air Source Heat Pump that is […]
