Sawing to new heights


For a complete overall of the back of this 1930’s property, a ‘SAW TOOTH’ pitch roof was used to exploit the stepped terrace of Algiers road to allow one side to be higher than the other and creating a double height feel inside.

This was combined with a significant pergola built from steel and charred cladding with a cast concrete chimney and an external fire sitting as the centre piece on the decking.

The theme was continued inside with polished concrete floors and chimney breast which mirrors the concrete fireplace outside.

Nominated as one of London’s best extensions in the “Don’t move, improve” Awards it received exposure and praise from the The Times and Evening standard papers.

Mixing Traditional and Contemporary at a Brockley house


This is a generously proportioned Victorian house in the Brockley conservation area. We part renovated this property including all of its bathrooms, heating, and the main downstairs, double height extension. Traditional materials and style were mixed with contemporary ideas to produce a lovely extension which flows seamlessly into the original Victorian building. The main feature of the double height ceiling adds the level of grandeur expected for such a sizeable property.


A Classic Victorian Make-Over


This south London project was a full interior & exterior renovation and extension. The property was taken back to the brickwork throughout, before extending it to provide a spacious kitchen/dining room. Original features were re-instated including cornice, panelling, fireplaces, parquet flooring and built in cupboards. Bricks saved from removing one of the original chimneys were upcycled into the new extension giving it character and a link to the Victorian house.



Dulwich Extension & Refurbishment


Designed by the architects Gruff Ltd, this Dulwich house was given a generous, contemporary extension for the growing family to expand into. The clever, cantilevered bay allows for a more functional use of space over the statement window while the bespoke carpentry in the corridor provides integrated storage and seating. Clad in anthracite, grey panels, the sleek exterior blends with the original Victorian building whilst remaining discreet. 


 2 becomes 3 in this Central London Renovation


Our client, an interior designer, benefitted from an outstanding location, but little space. We therefore re-configured the internal rooms to create a third bedroom, by moving the kitchen into the study.  We refurbished the rest of the flat at the same time, creating an innovative breakfast bar from reclaimed oak and built in wardrobes in the bedrooms. This was all achieved whilst keeping the original features in this listed building. 




A Georgian town house gets a new look


This house needed space and light breathed into it. By removing the wall between the kitchen and living room and then offsetting the kitchen units into the large hallway the ground floor was given the feeling of space it needed.  Upstairs the ensuite was transformed into a wet room with a new window into the bedroom which allowed light through but obscured glass below head height still gave privacy. A heated mirror was used in place of a tile to allow the customer to shave in the shower without a foggy mirror!



A fresh design for tired Victorian Flat


In this property we were briefed to bring the 'sunshine' to Brixton. The bathroom was based on a classic Moroccan theme and the small extension was given a Greecian feel with its exposed painted beams and plastered shelving units. Modern building techniques were used to bring light in to the space with bi-fold doors, flush roof light and patent glazing, which was cleverly offset with a rattan ceiling given the whole extension an exotic feel. A window seat was created to give the customer an area to read in, which also folded out as a bed to give the one flat more flexibility.
