Space on One Level
A single-storey extension adds ground-floor space for a kitchen, dining area or family room. Cooksey Renovation coordinates the build around the agreed design, site conditions and approval requirements, with Lance as your main contact through to completion.
01
Create space to cook, eat or relax, with the new room and its connection to the house planned around daily life.
02
Consider the garden, boundaries, access and existing house before deciding where the room goes.
03
Lance coordinates the building work and trades, from the shell through to fitting and making good.
Agreed Scope
Your quote defines the shell, roof, connection and interior work included, based on the proposed room and required design information.
Plan a rear kitchen extension, dining area or family room around how you will use it. The opening into the existing house, routes through the space and any making good are considered together, with structural design where required.
The foundations and drainage are planned for the plot and proposed design. Ground conditions, existing drains and access shape the work. The agreed scope covers the foundations, walls and connection to the existing building.
A flat or pitched roof needs to suit the house and proposed design. Rooflights and glazed doors are considered alongside insulation, ventilation and solar heat. Roof covering and rainwater drainage form part of the agreed shell work.
Once the shell is weatherproof, the agreed services and interior work follow. A kitchen may need different plumbing and electrical provision from a family room. Heating, plastering, fitting and flooring are specified in the quotation.
At the visit, we look at the house, garden and access, then discuss the room you want to add. The proposed design, approval requirements and building scope guide the next steps and quotation.
Before We Start
Single-storey extension cost and timing depend on the size, ground conditions, roof design, connection to the house and interior specification.
The quote considers size, foundations, drainage, roof and access. The opening into the house, glazing, services and chosen interior finishes also shape the agreed price.
Timing follows the required design and approvals, shell construction and fit-out. Ground conditions, weather, access and product lead times help shape the build programme.
Welsh planning requirements depend on the house, previous additions and proposed work. Building regulations are a separate check, covering structure, insulation, drainage and more.
Renovation Examples
The gallery shows examples of Cooksey’s renovation work, including kitchen fitting and room preparation. Use these finishes as a starting point when discussing the inside of your extension.
Our Process
Lance starts with a site visit to understand the house, garden, access and room you want to add. The proposed design and approval requirements inform a written quote for the agreed scope. Foundations, drainage, walls and roofing are coordinated before the interior fit-out. Any structural opening follows the required design. Lance remains your main contact as the trades complete services, fitting and making good.
Helpful Answers
These answers cover room choices, roofs and approval requirements to help you plan a practical single-storey addition around your home, available plot and existing property layout.
A kitchen and a family room can use a similar shell, but their services and finishes differ. Kitchen plumbing, drainage, electrics and extraction are planned around the proposed layout.
Some extensions fall within Welsh permitted development limits and conditions. Planning and building regulations are separate checks; most extensions need building regulations approval. Read how construction work on a home is managed before a start date is set.
The choice affects the appearance, structure and planning considerations. It depends on the house and proposed design, including roof height, drainage, rooflights and the connection to the existing roof.
It may do, depending on the plot and space beside the house. We consider the garden, access, boundaries and connection to existing rooms when discussing a rear or side addition.

From initial consultation to finished job the Cooksey were brilliant. Always looking on time, worked a full day, cleaned up after themselves and made sure we were completely happy with the work. Very friendly and professional. Covered every aspect of the installation of a new bathroom from liasing with suppliers to the electrics , plastering and tiling. Highly recommendedPosted on Google![]()

We cannot recommend Lance and the team enough. From beginning to end him and the team were professional, knowledgeable and communicative. Lance did multiple visits to us before starting work to ensure the best end result, our bathroom was a difficult refurbishment to say the least, but the final result is a testament to Lance and the teams skill and determination. When the work was being completed they were clean and tidy, often worked incredibly long days and kept me informed on any changes or challenges. He worked with us to keep to our budget updated us on any additional material charges. My neighbour even commented on how friendly and polite they all were. I have already recommended Lance to multiple people but will also have them back for any other renovation we need completing in the future. I wouldn't go with anyone else now.Posted on Google![]()

Recently had our Bathroom renovated by Cooksey Renovation; they did a fantastic job throughout and transformed our bathroom! The quality of their work is to a very high standard. They arrived on the agreed date to commence the renovation, were on time every morning, cleaned up after them every evening, and were pleasant and communicative throughout. I can’t recommend this company highly enough and would certainly use them again or recommend them to friends and family.Posted on Google![]()

Cooksey renovations and the team did an amazing job with our new kitchen and flooring. The job needed blocking up doors, windows and a fair bit of plastering. They were all really tidy and cleaned up after each day before they left. I'm so happy with the work they have done. Thank you!Posted on Google![]()

I cannot recommend Lance and his team enough! They have renovated both my bathroom and en-suite as well as repairing and replastering my living room ceiling following existing water damage. When I moved into my house, I knew there was gonna be a lot of work to do following previous leaks in the en suite and previous bad workmanship. All the team were professional, trustworthy and skilled in how they transformed my house. They kept everything clean and tidy (I even caught them hoovering my doorstep at one stage!) and made the house useable in between their working days. I had a very specific vision and they were able to make my dreams come to life and I’m so pleased with the end result. They ripped out my old suites, replaced rotten floor boards, rebuilt damaged walls and install all new paperwork. Nothing was too much trouble and they were also the most competitive quote I received. I have a kitchen and artexed ceilings to be renovated in the new year and there is no one else I would consider using. Thanks guys! I really love what you’ve done!Posted on Google![]()
