What makes us different

We are trusted professionals

Over two decades is a long time to be converting lofts – not to toot our own horn, but we think we’ve gotten pretty good at it! Our smooth-running team is made up of professional experts in all stages of loft conversion, who are there for you every step of the journey. We ensure that our customers always have the right person to talk to when needed: you will have a dedicated loft conversion project manager in our office, and a contracts manager who will regularly visit the site to check that everything is progressing according to plan. Your home is in safe hands with Build Mulder Ltd.

We have an outstanding reputation

We have transformed homes across Surrey, Hampshire, Berkshire and South London, and we are proud to say that our reputation attests to that. Our clients’ testimonials and reviews can give you a flavour of the impact our work has had on their lives, from adding space and light to increasing property values in many cases.

 

Our work is on time and in budget

Before starting a project, we always establish a clear timeframe and budget with our client – and we stick to it. Loft conversions take between 8-to-10 weeks, and our pricing is reasonable for an excellent job. Our projects are always finished on time, and on budget.

 

Professional Design Consultation

At the start of your project, we will send a surveyor to assess your property; our RIBA qualified architects will then draw up a set of plans in direct consultation with you. Once you are completely happy with your plans, we will complete your structural calculations and send your plans to the council if necessary – making everything as streamlined as possible for you.

10 Year Comprehensive Guarantee

We take great pride in our work, and hold every project to the highest standard. But we don’t want there to be the slightest concern in the minds of our customers, so we provide a ten year structural guarantee for your new loft conversion.

 

We take care of everything for you

The vision and comfort of our customers is our highest priority. From start to finish, we work with your needs to make things as simple and hassle-free for you as possible. Our ethos is to always go the extra mile for our customers.
