A rear kitchen extension on a sloping garden plot, opening the back of the house into one bright kitchen, dining and living space, completed through to building control sign off.

Project Overview

This project involved a single storey rendered extension across the rear of a detached family home on Hillside Avenue, with the old rear wall opened up on structural steel to create a full-width kitchen, dining and living space. The garden falls away steeply behind the house, so the works included a reduced-level dig, a block and beam floor and, as an agreed extra, a new retaining wall to the garden.

What the family needed

  • A kitchen that connected with the dining and living space rather than sitting in a separate room behind the garage
  • Direct access and views out to the garden and the fields beyond
  • A separate utility, with the garage kept for storage
  • Plenty of daylight in a deep plan, achieved with rooflights
  • A finish ready for their own kitchen fitters

Works delivered

  • Construction phase plan, RAMS and building control notification
  • Reduced dig, trench foundations and engineering brick below DPC
  • Block and beam floor with rigid insulation and concrete oversite
  • Cavity blockwork superstructure with structural steel to the new opening
  • Insulated flat roof with EPDM covering, lead flashings, fascias, soffits, guttering and rooflights
  • Render finish to tie in with the existing house
  • First and second fix joinery, plumbing and electrics, NICEIC certified
  • Insulation, drylining and plastering throughoutd
  • Client-supplied windows fitted and coordinated with their supplierd
  • Building control managed throughout to sign offd

Just at the end of a 6 month renovation project with Matt, Dean and team. The quality of work is exceptional, they are honest, reassuring when we couldn’t see an end to it all and met up with us whenever we had any queries. All the lads that came round over the past 6 months have been hard working, polite and very easy to be around. They went the extra mile for us and we highly recommend them.

Newhey have just completed a loft renovation at our property. They have been punctual and polite throughout. Newhey are great at finding solutions and ‘rolling with the punches’ which an old house like ours will always give! Newhey has been very adaptable throughout the project and we are happy with the end result which has given us a much improved living space. Thanks!

We recently used Newhey for our kitchen extension, and Matt, Dean, and the whole team did a fantastic job from start to finish. They bent over backwards to make sure we got exactly what we wanted and worked hard every single day to keep the project moving. As with any building work, especially when you're living without a kitchen for several weeks, there are always challenges along the way. However, the team made the process as smooth and stress-free as possible. They were always willing to come back and resolve any issues quickly and their pricing was really fair. We're delighted with the finished result and wouldn't hesitate to recommend Newhey to anyone considering an extension or building project. Thank you to Matt, Dean and the team for all your hard work!

It's my absolute pleasure to write a review for Newhey following completion of our loft conversion and dormer refurb. From our initial enquiry regarding options and prices through to completion, the customer care from Newhey has been amazing! Matt and his incredible team of friendly, enthusiastic, talented and hardworking lads have transformed our once useless space into a bathroom, bedroom, dressing room and store room. I was informed at each stage with what to expect and timescales. There were no empty promises or wasted days and our project ran like clockwork thanks to all involved. I would recommend Newhey in a heartbeat, and want to thank all the guys who helped transform our loft - you are all absolutely amazing!

We couldn't be happier with the work that Matt, James, the team at Newhey and all of the trades that have helped build and refurbish our home. We planned for a 2 story extension and a house wide upgrade including 3 new bathrooms/ w.c., new kitchen, electrical rewire and new heating system. The work has taken a little under 4 months to complete with only a few minor snags along the way, which Newhey promptly resolved. I would certainly use them again for any future projects and would thoroughly recommend them to anyone else looking to complete a project similar to ours. Thanks to everyone that helped us move into our dream home and the team at Newhey for making it into a reality!

A great experience with Newhey from quote to completion! The team of James, Dean, Levi and Jay were amazing. Always prompt, delivered in the rough time scale I was given, dealt with minor hold ups along the way always left the space they were working in tidy. Highly recommend. See you for phase two!

Couldn’t be happier with our double storey extension, Newhey have been great, along with all the trades they’ve involved along the way. We’ve been kept really well informed by Matt and James, which has really helped to navigate building work around usual family life. Our daughter now has a double bedroom to play in, and we love the space underneath with the addition of a cosy lounge and log burner. We wouldn’t hesitate to recommend Newhey to friends and family, thank you for all your hard work!
