I reached out to Ascania Architects as I had a complex planning permission situation, with little to no hope of acquiring permission due to a mishandled application by a previous architect. However, Rodney from Ascania engaged proactively on the topic, clearly explaining how we can refute the reasons for the refusal, being honest in his opinion and how we can approach a new permission. This has been massively helpful and I would recommend Rodney for the great communication and expertise.

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.

Vlad was brilliant to work with. He did feasibility studies for few properties that we were planing to buy. He delivered detailed reports and explained to us pros and cons for each property and what was achievable in therms of planning and renovation. Excellent communication, prompt to complete the work and the work was to a very high quality - exactly what I required. Highly recommend Vlad.
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.
