Design & Build Projects

Client : Mr and Mrs J

Location : Woking, Surrey

Description : Ground floor rear kitchen extension. 


To take down and removed the existing rear conservatory and to design and build a modern kitchen / dining room extension. Our build program for the work was extended from 8 weeks to 14 weeks when Mr and Mrs J asked us to include changes to the lounge, refit the family bathroom, build a new patio at the rear and re-lawn the front garden. Gas and electric meters were relocated to the front of the property and unfortunately Pitch Fibre pipes were discovered which were removed by a licenced contractor. This caused a minor time delay and an additional unforseeable cost which came out of the customers contingency fund.


Overall design and build cost £90,000

Customer feedback received Dec 2016
Left the feedback a bit late but the advantage is that I can now speak as one who is living with the new extension and loving it.

Andy was very detailed about every point in the design. He tried multiple designs and various combinations to optimise for space, comfort and light. He took care of the whole process of design, getting the design approved and in the end managed the building project as well.

I cannot adequately put to words how pleased I am with the finished product. This has made a great improvement to our lives.

As with all building projects there were many challenges. Getting the electricity and gas boxes moved and coordinated was one major logic effort that comes to mind. Andy took charge of every step in the process. He planned well, stuck to the quoted prices (and constantly kept pushing for better ones). Went well beyond the call of duty on many occasions.

Cannot recommend Room-by-Room (UK) Ltd enough.    Mr & Mrs J.

To take down and removed the existing conservatory and garage by hand rather than machine as part of the party wall agreement. Construct retaining walls first along the boundary before work commenced on the main structure.

After the house extension was water tight the internal fixtures and fittings were installed and the house was completely painted inetrnally and externally. The extended driveway was treformed and Tegular block paving laid to fall into new channel gullies draining into two new purpose builkt soak-aways.
