1. St John's Wood,  NW8  - House Refurbishment


A property developer required a complete overhaul of their newly purchased four bedroom, three story townhouse. The ground floor was extended into the existing garage creating a large open plan living area with views out to the garden. New solid European Oak floors were installed throughout the property and a bespoke solid European Oak stair was installed to connect the ground floor to the master suite.


Each bedroom includes a private en-suite shower room whilst the master suite features both a bath and shower with a roof light overhead. The architects demanded open layout, clean lines and crisp contemporary details. Our builders in London interpreted the brief, surpassed the construction challenges and delivered a beautiful contemporary home. 




2. Maida Vale W9 - Flat Refurbishment


This three bedroom apartment in Maida Vale was completely refurbishment over a two month period by a team of our builders in London. The flat was completely gutted, the layout of the rooms were reconfigured to maximise space and create a living area that is both comfortable and functional. Partition walls were knocked down to enlarge the bathroom and kitchen and a new W/C was added.


New central heating was installed throughout with a new high efficiency combi-boiler. The flat was completely rewired with new switches, sockets and light fittings. Antique Oak flooring was laid in the living room and bedrooms. 




3. Chiswick W4 - Side Return Extension


Sigma Construction UK was approached to build a new extension and refurbish the ground floor of this Victorian London mid terrace house. The brief included the demolition of an existing poor quality lean-to extension and the opening up of the living area. The house and extension were externally rendered and painted white by our builders in London (London builders) to visually tie together the old and new.



Timber decking rises up to meet the new glazed opening and connect the house with the lower garden. The interior was finished to a high standard with a calm, neutral material palette, and new floors were laid throughout. 



4. Clapham SW4 - Kitchen Extension


A young professional couple requested a ground floor refurbishment and new build extension to their small Edwardian terraced house. Sigma Construction UK, one of the most sought-after builders in London, introduced a light and airy addition to the house by demolishing the side wall and extending the house full width to the neighboring boundary.


The complete build is project managed by our experienced team who work closely with the relevant statutory bodies and officers to ensure the streamlined delivery of the final product. The design team works closely with the client to develop the layout of their kitchen extension and to specify a material palette in keeping with their personal taste and requirements.  




5. Farringdon, EC1 - Penthouse Renovation


Sigma Construction UK completed the high-end refurbishment of a Central London penthouse for a private overseas client. As builders in London we are well positioned to manage and deliver turnkey projects for international clients. This duplex penthouse provides the client with a unique perspective over London, affording panoramic views over key architectural landmarks from the comfort of a glazed rotunda.


The centrepiece of the apartment is a glazed circular kitchen and living space that is linked by a spiral staircase in a double height atrium. Above the stairs, a bespoke light installation cascades through space against a dramatic urban backdrop. Both bedrooms have lavish en-suite bathrooms with bespoke cabinetry and designer fittings.
