Breathing new uses into redundant structures is an important part of ensuring they remain for future generations.

We restored this listed barn and transformed it into additional accommodation for our clients. Key elements of the historic fabric were retained, with new fenestration to replace inappropriate modern glazing, with a new vertical emphasis more in keeping with the barns character.

Getting the proportions of a room feeling comfortable sometimes requires lateral thinking.

This extension to a Grade II* listed country house had a low roof, but the size of the room demanded a high ceiling to feel proportionally correct. A large cover and floating central ceiling section add interest and height but disguise the hidden structure behind.

Continuing our look back at 25 years of Alex Oliver Associates, we look back today to, perhaps, one of our favourite barn conversions.

By keeping as much of the historic fabric as possible, the converted building still looks and feels like the original, but transformed into comfortable family accommodation.

Long views through a house can draw your view through the building creating a long vista and making a home feel bigger than it really is. This architectural move is called enfilade.

Enfilade has been a device in architecture since the Baroque period and has been employed in a wide range of buildings from the Palace of Versailles to the Sainsbury Wing of the National Gallery to this restored farmhouse in Wiltshire.

The first impression of a home should be one of generosity of space, regardless of the size of the house.

If the entrance hall feels spacious and welcoming, even a small house will feel more comfortable as a result. The entrance space of this country house we restored in Wiltshire feels generous as a result of being able to take statement pieces of furniture and by opening into and adjoining space to make it feel bigger than it is.

In 2025 we are 25 years old, so over the year we are going to pick out 25 of our favourite projects from the archive to share with you.

Some are already well known, some less so, but all are special to us for different reasons and we hope you will enjoy this look into the first 25 years of our practice.

Kicking things off is our first ever project. This charming farmhouse was carefully designed to break down its visual mass with the main building formed from rubble stone being supplemented by a rear wing, a rendered service wing and a timber clad garage block.

Details make a building and we particularly enjoy the thinking that goes into each and every move we make as part of the design process.

A good example is the window above the porch of this country house we recently remodelled in a Gothic style. The window is divided by a transom to keep the rhythm of the fenestration, but the window itself sits behind, maximising the amount of glazing the window has.

Converting existing buildings is a balancing act of the proposed use with the character of the building.

Introducing new glazing can be particularly tricky, but sometimes the building itself will give you the answer. The large dormer window on this barn conversion in Wiltshire proved the inspiration for two further dormers, greatly increasing the light into the building, without appearing alien in character.

This Grade II* listed building dates back to the early 1700s and we never tire of visiting site as part of our ongoing design works for the owners of this Queen Anne beauty.

We’ve recently revisited a housing development we designed in Wiltshire, which included a courtyard of new build houses and a bungalow, but also two historic buildings dating back to the 1800s which were outbuildings to a long ago demolished mansion house.

These new homes are restored to the latest standards of insulation and services, but with the character of a bygone age that only an historic building can give.

Our conservation work sees us cross many thresholds, from the humble to the not so humble.

But the great thing about our projects is we get to look round some really interesting listed buildings, from a chocolate box thatched cottage to a castle. These two projects are examples of where we’ve provided strategic early stage advice to potential owners, helping them shape their future plans.

We do love a hand drawing here and we’ve been looking back through the archives recently to find our favourites.

This is one of Alex’s favourites. This elegant pair of gate lodges we designed for a country estate in Hampshire are, at the same time, both subservient to the main house, but still give the impression of what it will be like. The Georgians used gate lodges to signify the gravitas of their country houses, but still always remembered the fact that they were service buildings. A tricky balance, but one we are delighted to have struck here.

We like a wide range of architectural languages and which language we use for a project can be decided by a number of factors.

Chiefly though, when working with an existing building, the building itself will give us the correct direction. This country house dates back to the 1890s but the original design felt incomplete and unresolved. The language of the existing home suggested that a Gothic language would be the most appropriate direction and here is the finished article.

First impressions count. And nothing makes a good first impression like an well designed entrance hall.

For this project in Wiltshire we restored the entrance hall of this Grade II listed 19th century home, retaining, repairing and cleaning Victorian encaustic floor tiles and providing plenty of space for coats. The spaciousness of the room gives a generosity of feeling to the house from the very first room.

Much of the elements of Georgian architecture are evolved from the Classical principles first seen in the traditions of ancient Greek and Roman architecture.

The evolutions are continual but often reference back to earlier times. The first floor window on this Georgian townhouse includes what is known as a Venetian or Serlian (after Sebastiano Serlio) window. A Venetian window is a three part window with the central part being arched topped and the two symmetrical sidelights being shorter. All three are broken up by pilasters and are topped by an entablature.

You never know what you will discover when working on historic buildings. The rich tapestry of the past can sometimes throw up some unexpected discoveries.

Sometimes however the discoveries can merely be the result of a simple clean. This building in Wiltshire which we designed an apartment conversion scheme for sits right on the main road. Years of dirt and road grime has built up, obscuring to all but the most eagle eyed the phrase over the door. All it took was a bucket of warm soapy water!

The important thing when converting a barn is to use the fabric of the building to lead the design. That way the resulting property still looks and feels like a barn.

This can throw up some issues with low head heights, strange window positions and unusual corners, but this Grade II listed barn in Hampshire is a good example of the beauty that can be created by being led by what is there. As you can see from the before and after photos it has clearly been converted with softwood shiplap cladding being replaced by a return to traditional feather edged boarding, but is definitely still the same building and still a barn.

When working on old buildings a straight line is a rarity. Historic structures wobble, are out of plumb and are curved by the hands that made them.

The trick, when undertaking conservation work is to not fight this. Going with the fact the building is out of square keeps your intervention to a minimum and makes for a more authentic result. We took this approach for this Grade II listed Devonshire Linhay we worked on a few years ago and these pencil drawings we produced as part of the design process show how wonky some parts of the building were. All part of the charm.

We are lucky to see some very unusual buildings in the course of our conservation work.

You wouldn’t normally expect to find an industrial chimney in the back garden of a mid-1800s country house, but our research discovered an interesting story as to why. The settlement where the house is, was a built for the workers of a lumber mill which was originally steam powered. After three catastrophic fires as a result of embers catching sawdust alight, the chimney was moved further from the engines and into the garden of the mill owner’s house where it remains to this day, now under our watchful eye.

A lot of the pleasure of traditional architecture is the aesthetic pleasure that symmetry and balance of the elevations can bring to the eye. Where buildings are joined to others as part of the same composition, differing ownerships and approaches to maintenance can lead to this balance being upset.

The careful restoration of our Grade II* listed Georgian town house project brought harmony and symmetry back to the building by treating the elevation as a whole piece rather than two separate halves. Elegance is restored.
