Can’t recommend 2SS highly enough. They finished our large ICF extension project on time and on budget. Other builders told us it would take over a year but Svajunas and his team completed the work in 7 months. They have a huge team of people and arrived everyday around 7am! They often worked well into the evening sometimes leaving after 6pm. They are an absolute hidden gem of a building company-Svajunas and his wife Svajuna were project managers and gave us daily updates. They were honest and transparent with their pricing. They are a company that understand the building trade intimately, quoting a price they were able to stand behind and were very clear on the validity of that price. They are clearly very experienced builders. Our building project was a complex undertaking with some intricate carpentry due it being a very old building. 2SS has the full suite of skills to complete every aspect of the build. They never subcontracted so we only had to deal with Svajunas which made the project run extremely smoothly. We are so happy to have found this company. We will be calling on them again for phase 2 of our project.

James, Boyd and his team were brilliant. The work was carried out to a high standard and they were able to resolve any problems that occurred during the building work and kitchen installation. They tidied up at the end of each day making sure any equipment was not in the way. They were friendly, respectful and nothing seemed too much trouble. They were amenable and it was a pleasure to have them in the house. I would thoroughly recommend them to anybody in the future.

I can’t thank these guys enough for all they have done for me. I purchased my first property and it needed quite a bit of tlc before moving in. They were super helpful at times when I couldn’t make my mind up and were always more than willing to help and answer the millions of questions I asked. I honestly couldn’t have asked for more.

I am a project manager specialising in high-end refurbishment works, extensions and loft conversions. I needed a team to help me complete a project that was a 'back to brick' development and enlisted the services of Built-To-Last Construction. From the start of the project the can do attitude of the workers and their excellent work ethic, meant that the project was in good hands. From the point of starting work, to completion was exactly three months (Refurbishment, Renovate whole house, Loft conversion and Extension completed together) and the guys even worked through some of the most difficult weather conditions imaginable. Having worked with many construction companies in the past, I can confirm that Built-To-Last Construction is amongst the best of construction services available in the UK.

Mark Laws
We have completed two major projects with Gosch and the quality of design and finished result has helped us fully realise what we had hoped to achieve.
Simon’s superpower is to embrace all our ideas and then step them up, adding in real innovation, appreciation of the value of space and light, practical functionality and visual appeal.
There is no doubt we have ended up living in spaces with the ‘wow’ factor and benefitted from increased property value because subsequent buyers have also appreciated the design of the properties.
I recommend that anyone contact Gosch and get their ideas included in any project.

Extensions can take many forms: from single or multi-storey extensions, to conservatories and sunrooms, each extension is different. Even if you’re extending a house that is identical to one you have worked on before, the customer’s criteria are probably not going to be the same. One customer may want French doors while another may want bi-folding, so the challenge is always new with each extension. However, the majority of property extensions involve flooring, bricklaying, door and window installation, electrical work, and decorating. For bathroom and kitchen extensions, plumbing is also a key factor.
Pretty much any part of your home can be extended. As such, you can include additional features to your extension that would benefit that particular space or room. You may want to include a skylight in your kitchen extension. Or, you may need to include advanced ventilation in a basement conversion. Perhaps you need extra insulation for a rear extension that receives little sunlight. Whatever extras you may need, be sure to discuss these with your builder before any building work begins.
I have a core construction team of eight builders and a wider network of trusted tradespeople, such as electricians, carpenters, and plumbers. I also regularly work with several architects and construction engineers who are able to assist in extension designs and building plans. In my three decades in the construction industry, I have been fortunate enough to build a great team of builders around me, as well as take on five apprentices. While we have the necessary industry qualifications, experience really is the most important thing in the construction industry. I’m proud to say that hundreds of professional extensions and satisfied customers can testify to our ability and craftsmanship.
