House Refurbishment Hampstead NW3
House Refurbishment Hampstead  NW3

This Hampstead loft apartment refurbishment completed by Sigma Construction UK was a conversion of a loft space within a single family dwelling. Prior to the conversion, the attic space consisted of a series run-down of rooms with a very dark and steep access via a private secondary staircase, making it impractical and visually unappealing. more info >

St John's Wood Townhouse Renovation NW8 

The renovation of this four-bedroom, three-story house St John’s Wood was undertaken by Sigma, a construction company based in London, for an international investor.

The project necessitated a complete overhaul of this London NW8 property. The client’s vision was of a contemporary, yet luxurious, look with high-quality finishes that would meet the requirements of guests visiting the UK

The use of light colors throughout the house, as recommended by Sigma, added a light, yet substantial feel to the interior. The flooring installed by out London builders team was very contemporary, with the use of engineered oak timber combined with Carrara marble and a white lacquered finish on all the joinery. The fresh colors combined with the clean cut lines on the joinery gave this house renovation a lavish look to meet our client brief.

The kitchen we designed was fashionable and sleek, with subtly contrasting, custom-made units, and a light-grey marble-effect for the splashback and island counter. And in order to add a bit of warmth and ambiance to the kitchen, integral under-cabinet LED lighting was employed. The rest of the lighting was kept simple, with spotlights across the room and two pendant lights above the kitchen island.


To allow as much light into the home as possible, Our London builders installed full–height, floor-to-ceiling windows, which gives any guests using the first-floor bedroom a marvelous view of the newly landscaped garden, with its lush greenery and water feature.

To blend the ground and upper floors, a similar color palette was used throughout, with solid oak on the central staircase and a vertical feature batten wallwhich very effectively divides the space without completely closing it off, but also adds a modern look.

The en suite design in this London NW8 renovation, whilst still using a neutral color palette, offers more contrast. We created this by using darker tiles mixed with light walls and chrome sanitary ware, adding a masculine dimension, yet still in harmony with the rest of the house.


Sigma Construction UK also installed an Arabescato marble vanity unit and combined it with matte-finish, micro-brick porcelain mosaics on the wall and larger brick semi-glazed tiles on the floor. The shower is very simple, with a full-height mirror and a chrome border. The high ceilings and skylights allowed our team to introduce a darker palette here since there is more than enough light coming in to make the bathroom feel very spacious.

The carpets in the upper-bedrooms give them softer look, inside the rooms. The wardrobes have been fitted with illuminated clothing rails, which add a designer accent and glamour to our client's home.
