Two storey rear extension, internal re-design and front of house re-profiling.


I would thoroughly recommend Penco Builders. They were fantastic from start to finish. Greg is very professional, experienced and skilled. He took the time to understand what we were trying to achieve while making sensible suggestions about how we could improve our ideas and save costs. He was extremely responsive and dealt patiently with all of our questions both before and during the project. He was clear and honest about costs, timing and issues. That was really helpful to us, as we had not completed a major building project before. He was also knowledgeable about planning and building regs issues and guided us through the process smoothly. Greg and his team were really hard workers. They arrived at 07:30 without fail every day and worked very hard all day before leaving each evening, having first tidied up after themselves. There was not a single instance of the team ever being late or not showing up. They were completely reliable and dependable. Greg and his team were a pleasure to have around the site while the work was being carried out. They were unfailingly polite, courteous and friendly. Our kids loved having them on site. They were also very considerate - they even timed their breaks to fit in with our toddler's naps so that they would minimise the noise then. We lived in the house throughout and the Penco team tried hard to keep the disruption to our lives to a minimum (eg Greg kindly constructed a temporary kitchen for us). The project was scheduled to take 4 months. They started on time and actually finished a week earlier than planned. Greg kept me up to date as the project progressed so that we knew what was happening at all times. Greg scheduled a weekly meeting on-site to discuss progress and next steps. Greg was clear in advance about the costs and he provided an unbelievably detailed quote. He was happy to revise the estimate a few times while we made changes to the plan before the work commenced.

Conservatory removed and an extension built in its place


We are so happy with the work carried out by Penco Builders. The service they provided was exceptional. They were friendly, reliable, trustworthy and knowledgeable and were able to assist us with some other repairs to our home. We will definitely be using them for future projects and will be recommending their services to others.

Single storey extension to the rear and front of the property. Partial garage conversion to create utility room and cloakroom.


We have been delighted by the work done by Penco Builders Ltd to extend and improve our home. We admired the work they had done for a neighbour and followed their recommendation. The Project started with the concept and planning stage. Greg has a good eye for design and practicality. He listened to our ideas and suggested improvements to maximise the benefits to us. His design took account of our council's restrictions and was quickly approved by the council's officers. We agreed on a work programme, which was designed around us. The team arrived punctually and left the site in good order each day. Work which impacted directly on us was scheduled for days when we could be absent. Each phase of the project was delivered to time despite a lot of different weather conditions The quality of work was very high; weak lintels were identified and replaced, allowing modern windows, sympathetic to the house to be installed. The interior finishing (woodworking, flooring, painting) has been meticulous. Greg both worked with, and supervised his team closely. Greg invited our views at all times, offered us options on designs and constantly checked that we were satisfied. When the possibility of variation came up, Greg again was open to our thoughts, was open about estimates, and honoured his quotations. We look forward to working with Penco on other projects in our home soon.

Existing upstairs floor reconfiguration


I have heaps of praise for this fabulous company! The work these chaps have done on our cottage is second to none. A very professional team! The work carried out by these guys is excellent and to detail. Greg offers great advice on what you would need and preplans the jobs required to a timetable. A truly amazing team.



We hired Penco Builders to construct a two storey side extension for us. The work created an extra bedroom with ensuite and a number of internal alterations were also conducted and we are very happy with the result. We chose Penco for three reasons. Firstly they were recommended to us by a friend who had recently worked with them and we could see their build had been completed to a high standard. Secondly, when we first met with Greg he understood our requirements and we got the feeling we could work well together. Finally where other builders would only give ballpark quotes at an early stage, Greg produced a very accurate quote which enabled us to budget and was very helpful. Once work had started on the build progress was rapid and Greg’s friendly team worked hard to keep the build on schedule. Of course with any large project a couple of issues did arise but Greg met with us ASAP, often at short notice and solutions were found quickly. As we were living in the house during the build, Greg was mindful of this at all times and ensured minimal disruption for our family. We also added a few extra jobs during the build and Greg was happy to accommodate these. Any snags found post completion have also been rectified swiftly. The end result both inside and out is excellent. We’ve had many comments from both friends and neighbours at how well the extension matches the existing house due to the materials used and design, "it looks like it’s always been there" is a frequent comment.

Case Studies


Extension and Internal Reconfiguration


We have designed this extension, which involved reconfiguring the ground floor to create a fantastic upstairs space. Having established the client’s expectations, we produced a layout that addressed all their concerns, while keeping in mind the constraints of the planning permission. For this extension and refurbishment, we removed the part of the existing roof and built a full-width first-floor extension. This added a master bedroom with dressing room and luxurious wet room en-suite and  two bedrooms with a new family bathroom


 We had to remove the existing stairs and move the stairs to the new location fitting a beautiful oak staircase with glass balustrade. Glass stairways offer a spectacular finish and provide the extra dimension of more light and a greater sense of space. This property now has a fantastic new look.


Single storey extension and garage conversion.


We designed an L-shaped extension that wraps around two sides of the house. The project has 2 elements – an extension to the front of the house to create an open plan kitchen, living and dining area and the other being replacement of the garage to create a utility room and storage area. For both elements, materials have been carefully chosen to complement the existing house. The house was rendered with a light cream finish and the windows and doors were replaced with new double glazed UPVC units.


Double storey rear extension, internal re-design and front of the house re-profiling.


We were involved in this project from its conception and helped with initial designs, feasibility and also project management to support the clients during the work. The client’s main objectives were to create a larger open kitchen dining room and a master bedroom with En-Suite . The client wished the house to be modern in design while also fitting in sympathetically with the surrounding buildings. We were able to help and advise them on the potential design options and provide budget costs to help them with the decision process.


Transforming A Conservatory To An Extension


The initial plan was to convert the conservatory into a room and put a solid, insulated flat roof. Following a site inspection, consultation with building control and structural engineer it came to light that the existing foundation was not strong enough to support the extended walls and the flat roof. We have therefore prepared a new set of drawings and submitted the planning application on behalf of the client. The new proposal to build a timber frame single storey has been approved by the local authority and the project was successfully completed within a few weeks.  


Kitchen Extension


Penco Builders are excited to share with you our recently completed kitchen extension project in SO32 area. This project was designed to create a stunning open plan living space. The work involved excavation, block work, flat roof and lantern, knocking through into the existing kitchen, fitting a new kitchen, a new tiled floor extending into an existing house, plumbing, electrics, Bi-fold door, laying of a patio, new windows and door.
