We are two Polish partners and friends, who have been working in the construction industry for over 20 years. Initially we started as sub-contractors, but clients started recommending us to other family members and friends and our direct work increased very quickly. Finally we decided to start our own company and M&P Dream house Constructions was born. Over the past years, we have worked on over 200 projects – anything from new builds to extensions and kitchen & bathrooms. We handle small and large projects with the same level of detail, professionalism and service. We know, that if our clients are happy then we will be referred and therefore a 100% client satisfaction is key to our business. Over 80% of our work is through referrals and we wish to keep it this way.

Marek and Piotr (M&P Dream House) have just completed an extension project of my garden flat in London. This was a challenging project with complexities due to lack of side access, a big mature tree in the garden (deeper foundations) and shortage of building materials. M&P team overcame all the difficulties almost effortlessly! Everyone on their team had very good work ethic, polite and professional. I would highly recommend them to anyone.
