DesignBuild4U Middlesex

Bespoke home extension or conversion designs have traditionally been the preserve of larger and more expensive homes. However, DesignBuild4U in Middlesex are now offering a complete one stop shop beginning with our design team and ending with your complete home.

We are able to do this after many years of designing extensions, new homes, and conversions in the Middlesex area, which means we can take an off-the-shelf idea and modify it quickly and easily to suit your property type. Without fuss!

What we can do for your home

Using one of our own designs, customised to your home’s unique features, an extension will look amazing as it is matched to the existing exterior brickwork, and is guaranteed to be cost-effective.


Areas we cover in Middlesex
EdgwareEnfield – Feltham – Hanworth – Harrow – Hayes – Hounslow
Northwood – Perivale – Ruislip – Ruislip Manor – Southall – Twickenham

In London’s West End, many homes just can’t be extended outwards, but may be extended upwards into the roof space. Loft or attic conversions take advantage of the existing space up to the apex of the roof to create a new room, or space permitting, two rooms.

When combined with a roof replacement, we might even increase the average ceiling height for the conversion. In older homes a roof inspection is always advisable anyway, especially if work in the house could disturb roof trusses.

Garages and other outbuildings inside the property boundary are an easy conversion into a new guest room or home office, and if they are close to the original building could even be connected using one of our conservatory or sunroom ideas.

If you have a plot of land available to build your dream home, regardless of area or obstructions, our design team are able to create the perfect plans for your new build house.

Our complete one-stop-shop experience

DesignBuild4U will satisfactorily project manage any building work, something our customers tell us they love a lot. Rather than forcing the homeowner to manage distinct tradespeople, council permissions, materials supply, road closures, or scaffolding, we can do it all.

When required, we are also happy to provide design only services where the customer arranges the work themselves, or build only services where we work to a plan created by your architect. This option may not be suitable for everyone, though, so please ask us about our combined design and build experiences.

Regardless of the approach you take, DesignBuild4U will strive to produce the most cost-beneficial solution for your needs. In a competitive market we stand by our great prices for one-stop-shop project management.

All of the work carried out by DesignBuild4U in Middlesex will be performed to the highest standards, best quality materials and fixtures, and on time as per our contract. You really can trust us as most of our customers will attest, so ask to view our testimonials and previous home design project photos.

Our office hours are Monday to Saturday and we’d be delighted to talk about your home renovation. Complete the callback form and our representative will contact you soon.
