Single-storey rear extension build
Extension · West View

A small Teesside team. Built proper.

Mark Taylor Builders started because too many builders in the North East were quoting one number and finishing on another. We do things the opposite way.

Every project gets one of our two directors on site from first measure to final handover. Our trades are mostly the same five lads who’ve been with us for the better part of a decade, and we only take on as much work as we can do properly.

Six things, done
properly.

We don’t pretend to do everything. The work below is what we’ve done thousands of hours of, and what we’ll happily put our name on. After something else? Just ask. We’ll tell you straight whether it’s our wheelhouse.

Garden rooms, done in a week.

Got a conservatory that’s freezing in winter and unusable in summer? We turn it into a fully insulated, year-round garden room you’ll actually use.

Conservatory to garden room in just 1 week Most conversions are completed start to finish within five working days, with minimal disruption to the house.

We fit a modern SIP panel conversion system: structural insulated panels that replace the tired old roof and walls with a warm, solid, energy-efficient shell. The result looks and feels like a proper room, not a bolt-on, and keeps its temperature all year round.

We come out, measure up and listen to what you actually want. Free, no pressure, usually an hour. You get an honest read on whether the project is viable.
Stage 02
Quote & Drawings
A line-by-line quote, not a number on the back of a card. Drawings, structural calcs and planning advice arranged through our trusted local partners.
Stage 03
Build Phase
Set up Monday morning, weekly updates with photos, one point of contact throughout. We work to a written programme and tell you straight if something slips.
Stage 04
Handover & Warranty
Full snagging walk-round, building control sign-off, all certificates handed over. Ten-year workmanship warranty on everything we’ve built.

Hartlepool, Teesside and a sensible radius around it.

Most of our jobs are within a 30-minute drive of the yard. We’ll travel a bit further for the right project, but we like being able to pop back if something needs a second look.

They did our two-storey rear extension last summer and we still talk about how easy they made it. Quoted exactly what they finished on, turned up when they said they would, cleaned up properly every night.
